BR-952

BR-952: Difunctional Aliphatic Urethane Methacrylate Oligomer

BR-952 is an aliphatic urethane dimethacrylate. The low viscosity allows for ease of use in coating applications for the nail care and 3D printing industries. BR-952 can be used to provide a high gloss, tough coating, or 3D printed part. This material is also used in coatings for construction applications when improved toughness is desired for excellent durability. BR-952 provides an inherently high HDT of 143°C and a Tg of 159°C, and is inherently tin-free.
