Frequently Asked Questions
What are pigment concentrates used for?
Pigment concentrates are used to add high-strength colour to coatings and related systems during manufacturing.
What is the role of dispersing agents in pigment concentrates?
Dispersing agents help break down and distribute pigment particles during mixing and grinding.
Why is foam control important in pigment concentrates?
Foam can affect mixing and application, so defoamers are used to keep the coating process stable.
What are floating and flooding defects in coatings?
Floating and flooding occur when pigments separate during drying, leading to an uneven appearance on the surface.
How are surface defects controlled in pigment concentrates?
Specific additives are used to manage pigment movement and improve surface behaviour during drying.
