A-171 Silane

A-171 silane, Vinyltrimethoxysilane, is a monomeric silane used to incorporate pendant silane functionality into polymers as an alternative crosslinking mechanism, by radically initiated copolymerisation or polymer-analogous grafting. Being very reactive with water, it is also employed as a water scavenger and crosslinking additive in moisture cure systems, such as RTV silicone, MS polymer, and SPURsm -based sealants.

Typical Physical Properties

Features and Benefits

• Provides moisture-activated cure mechanism after being radically incorporated in resins.
  
• Improves physical and thermal properties of grafted polyethylene after moisture-cure.
  
• Improves physical and adhesion properties of acrylics being incorporated as co-monomer.
  
• Improves shelf life of hybrid sealants(SPURsm, silylated polyether) when used as a water scavenger.

Suitable for use in polymer systems such as:

Acrylic
Polyester
Polyoletin
Silicone
Silylated Polyether
Silylated Polyurethane
