COATING PROCESS FOR FLAT SURFACES WITH CURABLE (METH)ACRYLIC ACID ESTER GROUPS CONTAINING ORGANOPOLYSILOXANES

The process for coating planar substrates involves applying curable organopolysiloxanes which have been modified by means of (meth)acrylate groups to the surface of the substrates and curing the modified organopolysiloxanes by exposure to polymerising high-energy irradiation, where polysiloxanes con...

Zusammenfassung:The process for coating planar substrates involves applying curable organopolysiloxanes which have been modified by means of (meth)acrylate groups to the surface of the substrates and curing the modified organopolysiloxanes by exposure to polymerising high-energy irradiation, where polysiloxanes containing hydroxy-functional groups are reacted with, based on the hydroxyl groups, from 0.4 to 0.9 molar (meth)acrylic acid and up to 0.6 molar amounts of monocarboxylic acid containing no double bonds (sum of the acids
