Date:2016-05-16 16:25

SIPRO-771 Two-component  Silicone Structural Sealant is a two component room temperature curing neutral, high flexibility, high modulus silicone sealant. It has good adhesion and resistance to weathering performance, adjustable curing time.

Neutral fast curing, was sticky surface that is non-corrosive to most building materials without primer has good adhesion.

Structure assembly is mainly used for building hidden box walls can also be used to install automobile, shipbuilding and other pressure-resistant glass, sealed
