Chemical structure:

Properties

USi-402, 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 USi-402 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 USi-402, 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 USi-402. As a result, these

coatings demonstrate markedly greater

scratch resistance and resistance to chemicals.
