Polyurethane materials are a general term for a class of macromolecular compounds that have urethane structures in their molecular structure. They are usually prepared by the polyaddition reaction of diisocyanates and polyols. Polyurethane polymers possess both polar functional groups that allow for physical cross-linking and non-polar and flexible chain segments. When used properly, these po...

Let's learn about the characteristics of water-based acrylic emulsion! 1. Excellent Adhesion The polymer structure of water-based acrylic emulsion facilitates the flow and wetting of molecular chains on the substrate surface, resulting in close contact between the coating and the substrate molecules, achieving high adhesion. 2. High Pigment and Filler Loading Capacity, Significantly Reducing ...

Sometimes, a slight ammonia smell is detected in water-based acrylic emulsions, which confuses many people: is this normal or is there a problem? First, we need to clarify that acrylic emulsions themselves do not produce an ammonia smell. However, during their production, ammonia-containing additives may be added to adjust their performance or improve their stability. These additives gra...
