Product Details

Dynasylan® SIVO 203 is a new multifunctional aminosilane adhesion promoter that can be used for a wide variety of applications. Dynasylan® SIVO 203 is mainly dedicated for use 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. In addition, Dynasylan® SIVO 203 can lead to fast sealant curing and high-crosslinked products and it imparts both additional flexibility and hydrophobicity.

Benefits

Dynasylan® SIVO 203 exhibits excellent wetting on substrates and it forms weather- and moisture-resistant bonds to substrates which are typically difficult to adhere. The main benefits of Dynasylan® SIVO 203 in silylated polyurethane or MS polymer adhesives and sealants are:
  • Improved adhesion to Al
  • Improved adhesion to plastics such as PC and PET
  • Improved in elongation and modulus
  • Reduced yellowing and reduced staining of transparentend products

Typical Applications

Dynasylan® SIVO 203 is a versatile product that provides improved product performance and quality. Dynasylan® SIVO 203 is soluble in alcohols, aliphatic and aromatic hydrocarbons, butit can undergo reactions with ketones or ester solvents. Dynasylan® SIVO 203 may also be used as an additive or as a primer in coatings and as a primer in adhesives and sealants applications.

When used as an additive, Dynasylan® SIVO 203 can eliminate the need for special primers in numerous bonding applications. Specific systems that demonstrate improved adhesion when Dynasylan® SIVO 203 is used include RTV silicones and hybridsilane-crosslinkable systems. Loading levels of 0,5 to 2,0 wt. % of Dynasylan® SIVO 203 as an additive - calculated on the overall formulation - are typically recommended. Dynasylan® SIVO 203 can also be utilized to treat mineral fillers. The special functionalities may result in unique functional filler properties when Dynasylan® SIVO 203 treated minerals are incorporated into polymers.
