Bomar Oligomers® BR-952

1 of 88 products in this brand

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

Chemical Family: Urethane Acrylate/Isocyanate

Labeling Claims: Tin-free
