Properties

AC-251, as a co-monomer in polymers, can much improved wet scrub resistance and abrasion resistance thanks to crosslinking and better adhesion to the substrate. Silane- modified thermoplastics obtained by grafting with AC-251 can be processed further using standard techniques. On exposure to moisture, the silyl groups condense and function as crosslinking or adhesion points. By treating fillers with AC-251, mineral filled polymers can be obtained which exhibit improved mechanical and electrical properties. In addition, the particles are rendered strongly  water repellent, which results in improved filler dispersibility and thus facilitates processing. Organic surface coatings will adhere more strongly to inorganic substrates that have been treated with AC-251. As a result, these coatings demonstrate markedly greater scratch resistance and resistance to chemicals.

Applications

Silane AC-251 is an essential ingredient in many industries as below:

In the production of silane modified:  As binders in paints and adhesives

In the manufacture of pipes and cables: Made of silane crosslinked polyethylene

As an adhesion promoter:  In primers and coatings

In the production of organically modified fillers:   For cable insulation

Dip-treating glass fiber and inorganic siliceous filler
