Product Features

Dynasylan® SIVO 202 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 202 in silylated polyurethane or MS polymer adhesives and sealants are:

  • Improved adhesion to plastics such as PC and PVC
  • Improved mechanical properties

Product Applications

Dynasylan® SIVO 202 is a versatile product that provides improved product performance and quality. Dynasylan® SIVO 202 is soluble in alcohols, aliphatic and aromatic hydrocarbons, but it can undergo reactions with ketones or ester solvents. Dynasylan® SIVO 202 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 202 can eliminate the need for special primers in numerous bonding applications. Specific systems that demonstrate improved adhesion when Dynasylan® SIVO 202 is used include RTV silicones and hybrid silane-crosslinkable systems. Loading levels of 0,5 to 2,0 wt. % of Dynasylan® SIVO 202 as an additive - calculated on the overall formulation - are typically recommended. Dynasylan® SIVO 202 can also be utilized to treat mineral fillers. The special functionalities may result in unique functional filler properties when Dynasylan® SIVO 202 treated minerals are incorporated into polymers.

Product Applications

Dynasylan® SIVO 202 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 202 can lead to fast sealant curing and high-crosslinked products and it imparts both additional flexibility and hydrophobicity.
