PU resins
Chemical Formula According to technical sheet
Abstract
In the paint industry, thermoplastic acrylic resins are used for their excellent gloss, transparency, and resistance to yellowing, making them ideal for fast-drying lacquers and varnishes. Hydroxylated acrylic resins, containing reactive –OH groups, are used in two-component polyurethane systems, offering high adhesion, gloss, and chemical, mechanical, and UV resistance. Meanwhile, water-based, low-VOC styrene-acrylic emulsions are widely used in architectural coatings due to their good washability, color retention, and balance between hardness and flexibility.
