It’s Spring and our monomer product line is growing. These new products were selected for their low odor, low viscosity and low shrink characteristics, which makes them well suited for many applications including ink jet and 3D imaging.
GENOMER* 1120 (TMCHA) also offers very low surface tension (26 dynes/cm), shrinkage of 8.5%, shore hardness of D65, and good flexibility, which makes it a good choice for coatings for plastics.

GENOMER* 1231 (TCDDA) is a good choice where high Tg is required. It offers fast cure, excellent shore hardness of D90, shrinkage of 7.4%, and very good chemical resistance. GENOMER* 1231 also offers a relatively high refractive index (1.503) and can be used to increase this property in clear coatings.
