BERCHEM® 4842

BERCHEM® 4842 is a low molecular weight, high value-added sodium polyacrylate-based dispersant specially designed for pigmented paper coating formulations. BERCHEM® 4842 has the added value of not giving significant-high viscosities at higher dosages as compared to the competitive products. Proper coating dispersion is essential to achieving good coater runability and can significantly improve or eliminate issues such as scratching, weeping, and whiskering.
