Advantages
  • improved product performance and quality
  • excellent wetting on substrates
  • weather and moisture resistant bonds to substrates which are typically difficult to adhere
  • improves the adhesion to plastics such as PC, PET and AI
  • improved in elongation and modulus
  • reduced yellowing and reduced staining of transparent end products
  • fast sealant curing
  • high cross linked products
  • both additional flexibility as well as hydrophobicity
Other Applications

in adhesives & sealants to improve the adhesion of hybrid products (e.g.silylated polyurethanes, MS Polymers), RTV silicones, two part polyurethanes and two part epoxies to inorganic surfaces and some difficult plastic surfaces

Handling

It is soluble in alcohols, aliphatic and aromatic hydrocarbons, but it can undergo reactions with ketones or ester solvents.
Dynasylan® SIVO 203 is listed on EINECS/ELINCS TSCA IECSC ECL.
