Radiation-hardenable diluents for radiation-hardenable compositions

摘要

Radiation-crosslinkable diluents for radiation-hardenable compositions (binders) consisting of a mixture of triacrylates of a reaction product of trimethylol propane and ethylene oxide with an average degree of ethoxylation of from 2.5 to 4, the ethoxylated trimethylol propane being substantially free from trimethylol propane and having the following distribution: 4 to 5% by weight of monoethoxylation product 14 to 16% by weight of diethoxylation product 20 to 30% by weight of triethoxylation product 20 to 30% by weight of tetraethoxylation product 16 to 18% by weight of pentaethoxylation product. 6 to 8% by weight of hexaethoxylation product. The diluents effectively reduce the viscosity of radiation-hardenable compositions and do not have any adverse effect upon their reactivity or upon the properties of the resulting hardened products.
