SINOMER® UVU6600F is a hexafunctional aromatic urethane acrylate oligomer. It exhibits fast curing speed, excellent surface dryness, and forms films with high hardness (up to 3H), outstanding abrasion resistance, and good anti-cracking performance. It is specifically recommended for scratch- and wear-resistant coatings.
