Silicone auxiliaries - pollution resistant auxiliaries
Organosilicon auxiliaries used as dirt resistant auxiliaries
In some special fields (such as 3C) application of coating systems, usually have surface stain resistance requirements. Pollution resistant additives are mostly a variety of special structure of silicone additives, as shown in Formula (5), they usually contain some silicone group R can react with the system, and have some silicone chain segments can be extended on the surface, it is these extended silicone chain segments provide excellent pollution resistance. When R is hydroxyl, it can be used in polyurethane system and amino baking paint system. When the hydroxyl content is low, it is suitable for solvent based system. When the hydroxyl content is high, it is suitable for water based system. When R is a double bond of acrylate, it can be used in uv curing system. When the R group is epoxy, it can be used in epoxy systems.
