Urethane Acrylates are oligomers or polymers that contain a polyurethane backbone with acrylates as an end group. Polyurethane backbones are generally derived from reacting various diols with an excess of mono, di, or tri isocyanates in presence of catalysts. Acrylates are further end-capped using various hydroxy-functional acrylates. Diols used in the backbone can be polyether, polyester, polycarbonate, polycaprolactone, polybutadiene diols. Isocyanates used in the backbone are generally aliphatic or aromatic diisocyanates. Urethane acrylates are either monofunctional, di or polyfunctional molecules. Generally, these are in liquid form with viscosities ranging from < 100 cPs to > 200,000 cPs at 25oC.

Key application areas of urethane acrylates are in light curing coatings, adhesives, and encapsulants industries. Urethane acrylates are used in optical fiber coatings, as photopolymer, in self-cleaning coating formulations and more.
