色浆是什么东西？

色浆是什么东西？对于一个外行来说，确实有很多人不知道色浆是何物？
上周，上海彩生创始人虞幸芝在参加一个工业品学习交流活动的时候，一群来自全国各地的企业管理者或公司经理在一起交流。

期间有同学问：“你们是什么行业的？”
虞幸芝回答：“我是上海彩生公司的，我们是一家专业的色浆生产厂家。”
接着这个同学继续问：“色浆是什么？色浆是干什么用的？”

虞幸芝回答：“色浆是一种着色材料，也算是一种工业原料，色浆是由颜料干粉在表面活性剂，乳化剂等化学助剂的作用下，在高速搅拌和研磨的多道工艺下生产而成的液体颜料分散制品。也叫涂料色浆。所以大部分人不是太熟悉！”然后虞幸芝指指一起学习交流的同学身上穿的T恤衫，说“这个T恤广告衫胸前的印花图案就是用水性涂料色浆印花着色的！水性涂料印花色浆和涂料染色色浆就是我们上海彩生的主打色浆产品！”

有其他同学问：“这个衣服上的图案不是油漆印的吗？”
虞幸芝摇头笑着回答说：“这个是水性涂料色浆印花！纺织品印花和纺织品染色的一种成熟印染方法。可能你们觉得液体有颜色的东西就是油漆，但是一般纺织上是不会到油漆的。纺织品多数是直接接触人体皮肤的，要求使用的着色材料是环保安全的，普通油漆无法满足。”

同学继续问：“那色浆就是衣服纺织品用吗？”
虞幸芝回答：“其实色浆的用途很广泛，就纺织品而言，衣服，织物纱，无纺布，家装墙布等等！还有其它领域，比如日用化学品着色，肥皂，洗涤剂等；还有水性涂料或水性漆配色，木材着色，竹制品涂色！还有现在聚氨酯发泡材料着色，玻璃纤维着色，水泥着色！还有其他很多着色领域都会用到色浆！”

大家听了，眼睛睁大大滴，原来色浆使用是这么广泛！
接着虞幸芝还告诉大家：“色浆用途的确广泛，用户可以根据自己的需要，选择合适的色浆产品！而且市场上的色浆产品上千种，不同性能，不同颜料号的色浆比比皆是！价格高低不一，竞争也很激烈！ 但目前国内有客户使用色浆忽略从安全角度出发，一味比较色浆价格，忽略从安全角度选用色浆，导致很多安全隐患！如果大家在选用色浆的时候，一定要重视色浆的安全指标，水性色浆中微量有害物质如芳香胺含量，APEO，甲醛，重金属等。”

上海彩生的所有水性色浆产品均符合欧盟REACH标准,其中CTH系列水性色浆符合OKEO-TEX100成人接触皮肤的安全标准；BBH系列色浆安全升级，满足符合OKEO-TEX100婴幼儿纺织品使用要求！获得ECO-PASSPORT认证证书！

Caison water based pigment paste for coloring natural dry aqueous paint

Today, Manager Li is very happy because of  an order of water based pigment black paste for aqueous metel paint.  This application is new to us ,one cilent was finding the suitable water-based pigment paste for his aqueous paint in order to replace the oil based paint. The aqueous paint will be coated on metal surface, requiring natural conditions dry!

This customer had sent us five oild based paint samples as color reference, these paint would be replaced by water-based paint with the same color. He needed us to provide matched water based pigment paste for aqueous paint. 

Previously, the customer had cooperated with us for some times, he purchased water based pigment paste blue and greem, so he had already recognized the quality and service of Shanghai Caison pigment paste!

We began to make the color matching, the customer's requirement is extinction black, so we had to add a lot of barium, and the adding amount of black pigment paste is more, we recommended him to make stability testing before mass operation.  At last, we put 11.2% of KR-501 black pigment paste in the aqueous paint formula. Then the customer confirmed the color and offered the order, and he will receive the black pigment paste in 2 days. All of these are done in one week!

With the improvement of people's environmental awareness, with the stronger and stronger government's regulation of environmental protection, solvent-based metal paint with serious smell will be replaced by water based paint quickly. No smell and natural dry aqueous paint will be more wide application in the future.  It will greatly improve the operating environment, and reduce the emissions of toxic and harmful volatile solvent !

Self-drying water based metel paint is a good product. Working for matched water based pigment paste for coloring the paint is a major challenge and opportunity of the future development of Shanghai Caison Color.  

Water based black pigment paste for coloring

Carbon black is an important raw material for black pigment paste production. Different kinds of carbon black will bring different color hue pigment black paste, and the funtion will also be different.  Now we share some important information about carbon black and black pigment paste selection.

According to the production process of carbon black, there are furnace carbon black, tank black and so on;

According to the application of carbon black, there are rubber carbon black, ink carbon black and conductive carbon black;

Carbon black is in the form of particles, it needs to be fully moist and dispersed in the water based black pigment paste material formula. Experienced pigment paste engineers all know that carbon black is difficult to be dispersed, it needs to spend more time than other raw materials to be wet, pre-dispersing time is longer.  Oil absorption is an important indicator of carbon black, the carbon black with higher oil absorption will be smaller particle size, its specific surface area will be bigger, and more black. Of course, it is more difficult to be dispersed well.

So the black pigment paste is more black, the price is more expensive!  As the particle size of black pigment paste is fine, when the light through the black coloring layer, scattering effect of short-wave blue light will be stronger than long-wave red light. The figure is that spraying effect  on bicycle metal parts by water-based black paint, the right one is colored by CAISON 8 series water based pigment paste 8501 Black; the left one is colored by black pigment paste from another pigment paste supplier. Obviously, the right one is more black.

CTH-5000 Black pigment paste is a special black pigment paste produced by us, it is the super high blackness  in the black pigment paste market. It is often praised by users from the home and abroad!

Why should we spend more pigment paste for coloring paint to dark color?

Currently, many people like new ideas in their lives. They hope to color some dark interior wall or exterior wall, but they would find it is hard to prepare the dark color paint with white latex paint and water based pigment paste.

It is because that there are a lot of filled plastid pigments and titanium dioxide in latex paint. Generally, if titanium dioxide is less than 5% in coatings formulation, the coatings has poor hiding power. High quality titanium dioxide has high hiding power and white brightness. Every coatings engineer would know it.

After some testings, Shanghai Caison color engineers learned that even if adding up to 10% of caison brand high concentrated pigment paste to any brand white latex paint in the market, the client could not get paint with black enough, only be dark gray latex paint.

We will find following solution is right way to solve this question:

1. Coloring the paint by pigment powder, this just meets the low quality paint and useful;

2. To buy the latex paint without titanium dioxide base materials, this kind of latex paint has higher resin content;

3. Adding more pigment paste to prepare more dark color paint. But pigment paste has no resin, it will impact the fastness, smoothness and film-forming of latex paint. Because the surfactant in pigment paste would be destroyed by base materials of latex paint, and cause the accumulation of pigment particles in pigment paste, this maybe result the loss.So here we remind consumers that the adding amount of pigment paste is no more than 10% in paint. 

Solutions in future :

We will launch good latex paint to be suitable for dark interior coloring. At present, the new product is still in the evaluation and testing.

How about the fineness of water-based pigment paste?

The fineness of water-based pigment paste is an important technical index to measure the pigment paste quality.  Pigment paste fineness inculdes two parts: one is the size of pigment paste particles; another one is the uniformity of particles.

Through the role of dispersant, wetting agent, emulsifier and other agents, pigment particles in pigment paste slowly forms the small suspended particles after strong shear force of grinding machines in water based system. At last, pigment paste is produced.

According to the experience of coatings engineers, the smaller of pigment paste particles, the better of fineness, and the pigment paste coloring strength is higher. However, the finer of pigment paste fineness, the higher request to dispersion equipment, dispersion medium and the dispersion time. Pigment paste manufacturers should pay more costs for the production of pigment paste.  Also the uniformity of pigment paste fineness is very improtant quality indicator.  So how to detect the pigment paste fineness by us?

1. To observe the fineness of water-based color paste with a microscope, is the most commonly method to detect the fineness of aqueous pigment colorpaste. Usually, the inspectors of pigment paste manufacturers use a magnification of 640 times the biological microscope, eyepiece contains one tenth of the micrometer. The fineness of the pigment paste is observed with the micrometer.

2. Observe the pigment paste fineness  with advanced particle size analyzer.It is more easy.

3. Direct comparison in the application. Prepare a paint formula of 5% pigment paste added amount, another formula is inculding 0.02% pigment paste adding amount. Then scrapes on the substrate. To compare the color strength, the better coloring strength, the better pigment paste fineness.

The pigment paste grinding technology and equipment of Shanghai Caison Color company is leading in the industry, so the fineness of pigment paste is very fine and uniform, the average particle size would be reach 1 micron.

Pigment paste naming and classification

Pigment paste, is originally used as a coloring raw materials for coatings. Now it is widely used for coloring in different areas, and the names of pigment paste are more and more.

Many pigment color paste users like to look for pigment paste according to their application areas;

Many pigment paste factories name the pigment color paste based on the raw materials and system performance;

Scientific research people would like to rename the color paste depending on the suitable paint binders.

The development and application of pigment color paste is going to more industries, pigment paste has much more names in these years. As we know, the following five naming methods are more prominent:

First, pigment paste is classified based on raw materials property: pigment color paste, inorganic pigment paste, organic pigment paste, water-based pigment paste, oil based pigment paste, carbon black pigment paste, titanium white color paste, iron red pigment paste and etc.

Second, it is classified according to the characteristics: generic pigment paste, liquid pigment paste, high concentrated pigment paste, super concentrated color paste, high gloss pigment paste, thermochromic pigment paste, transparent color paste, high covering pigment paste, nano pigment paste,red color paste, black color paste and etc.

Third, it is named accoording to the functions,is also the most extensive way of naming pigment color dispersion: pigment paste, interior or exterior wall pigment paste, building color paste, ink pigment paste , epoxy pigment color paste, machine pigment paste, UV pigment paste, acrylic pigment paste, PVC coloring paste, silica gel color paste, unsaturated resin pigment dispersion and etc.

Fourth, pigment dispersion is classified based on the procurement channels or product brand name, is also more common, such as: imported pigment paste, domestic pigment dispersion, Shiming pigment paste, Casion pigment paste, Silian pigment color paste and etc;

Fifty, according to the environmental features, they can named as: eco-friendly pigment paste, halogen-free color paste, zero formaldehyde pigment paste and etc.

Pigment paste is a pre-dispersion pigment preparation which can be used for multi-industry. Due to the developing of coloring requirement and downstream indusrtry, the pigment paste types will increase more and more. It is an opportunity and is also a challenge to us.
