APTES(Crosile-550) Applications

Crosile-550 contains two different functional groups - amino and oxethyl in its molecule.
It is able to form bonds between organic polymer and inorganic fillers to improve their,bonding and upgrade mechanical, electrical, water resistance of the polymer based composite.
It is suitable for polymers such as epoxy resin, phenolic resin, cyanuramide, PVC, polyacrylate,polyurethane etc and inorganics such as glass fiber, glass cloth, glass bead, white carbon black, French white, clays, pottery clay etc.
The product is also used in the synthesis of amino silicon oil and its emulsion
