GENOMER* 4230 is a difunctional aliphatic urethane acrylate for radically-curable inks, coatings and adhesives.
Cured films of GENOMER* 4230 are soft, flexible and non-yellowing.

• high flexibility
• low yellowing

GENOMER* 1116 – THFA; Tetrahydrofurfuryl acrylate
GENOMER* 1117 – CTFA; Cyclic trimethylolpropane formal acrylate

GENOMER* 1116 is a polar, low viscosity, monofunctional, heterocyclic monomer that improves adhesion to various substrates.

• low viscosity
• low shrinkage
• good adhesion
• hardness
• weatherability
• chemical resistance
• heat resistance
• abrasion resistance
• impact strength
• water resistance

GENORAD* 10 is a surface-active additive that enhances flow properties of
inks and coatings. It is silicon free and improves gloss and adhesion. Typically it is used in concentrations from 1 to 10%, depending on the pigment, binders, photoinitiators and their concentration.

Traditional UV-curing equipment, particularly in the graphic arts industry, has relied on medium pressure mercury lamps to provide spectral output at wavelengths consistent with the absorbance profiles of common photoinitiators. In this scenario, photoinitiators can be chosen and mixed/matched to provide good cure response, especially where pigments and fillers interfere with light absorption.

RAHN´s new Lab Report ´Shrinkage of UV Oligomers and Monomers´ is now available. The shrinkage behavior of RAHN oligomers and monomers was determined quantitatively and documented accordingly. Purpose of this report is to address key subject of shrinkage in UV/EB cured formulations.
