Used as an organic silicon additive for coating resin modification
Organic silicon material usually has some special properties, such as surface smooth, wear resistance, weather resistance, low temperature flexibility, such as performance, through some with reactive functional groups of organic silicone materials as modified additives, can be in the introduction of organic silicone resin system segment, and to introduce the excellent properties of organic silicon coating system, as shown in figure 2. The silicone materials used for resin modification have various functional groups and are usually silicone polymers with reactive groups at both ends. Silicone materials with carbon hydroxyl groups usually have good reaction ability with polyurethane materials, can be used to modify polyester or polyurethane resin; Silicone material with epoxy group can be used to modify epoxy resin; The silicone material with two ends of the acrylate double bond can be used for the modification of light curing resin, and the silicone material with the acrylate double bond can also be used for the synthesis reaction of silicone modified emulsion; Organosilicon materials with amino groups can be used for the synthesis of organosilicon modified polyimide resins for some high-end applications; Organosilicon materials with carboxyl groups can be used as powder coating resin modification and participate in the reaction.
