- Chemical Family:Acrylics & Acrylates
Viscoat #155 (CHA) has a simple structure. Cycloalkyl structure induces weatherability with low viscosity, good compatibility and lower shrinkage. As compared with isobornyl acrylate, its viscosity is very low. CHA has relatively higher Tg than other acrylic monomers. Sometimes CHA is used for photoresist because it is easy to hydrolysis because cyclohexanol is secondary alcohol.
