ACURE™ 550-105

1 of 14 products in this brand
ACURE™ 550-105, an acid-free tetra-functional polyester acrylate, acts as an acceptor in ACURE™ chemistry, contributing to exceptional coating properties. Notable for its light color, low irritancy, and overall excellence, ACURE™ 550-105 imparts high cross-link density, good gloss, early hardness development, and robust chemical and mechanical resistance to formulations. The resulting cured film is resilient, avoiding brittleness. Additionally, it meets labeling claims of being VOC-free, isocyanates-free, and having a low carbon footprint (PCF), offering an eco-friendly choice for solvent-borne coatings.
