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.
