Organic Silicon Oligomer

Silicone oligomer is a relatively low molecular weight silicone resin , due to its structural characteristics, it plays a great role as a resin monomer, as a modifier of organic resins, as an interface modifier, and is a very unique product.

(1) As a resin monomer

Main features: waterproof, weather resistance, high hardness

Application: Body Coatings, Floor Coatings, Hydrophobicity

(2) as organic resin modifier

Main features: adhesion, weather resistance, water resistance

Applications: substrates, sealing materials, adhesives, adhesives, coatings for building materials

AR type product

AR type oligomer, because it contains in addition to alkoxysilyl groups Reactive functional groups, which can thus function as adhesion aids between the organic resin and the inorganic base material, can be referred to as oligomeric coupling agents.
