Dynasylan® 1146

Dynasylan® 1146 diaminofunctional silane may be used in coatings, adhesives, and sealants to improve the adhesion of amino­reactive resins. These are resins such as silicones (RTV), two­part urethanes, silylated urethanes, MS polymers, and two­part epoxies to inorganic surfaces, plastic surfaces, and inorganic fillers. Dynasylan® 1146 silane is characterized by randomly­distributed linear and cyclic oligosiloxanes and fullfills the OECD polymer definition. Its low volatility and viscosity make compounding easy. Dynasylan® 1146 silane produces significantly less by- product (VOC) and has a correspondingly low odor level during application.

Product Benefits
  • Because of its unique oligomeric structure, Dynasylan® 1146 silane exhibits excellent wetting on substrates and forms weather­ and moisture­resistant bonds to substrates with difficult adhesion properties.
  • The diamino functionality provides a reactive site for amino­reactive resins, whereas the alkyl functionality imparts hydrophobicity. Use of in silylated urethane or MS polymer adhesives and sealants results in: superior wet adhesion to inorganic (e.g. concrete, aluminum) and organic substrates (e.g. PVC) improvements in elongation and modulus, allowing the formulation of highly elastic products negligible yellowing and staining

Product Applications
  • Dynasylan® 1146 silane is a versatile product that provides improved product performance and quality.
  • Dynasylan® 1146 silane is soluble in common organic solvents (e. g. MeOH, EtOH, MEK).
  • Dynasylan® 1146 silane may be used as an additive or as a primer in coatings, adhesives, and sealants applications.
  • When used as an additive, Dynasylan® 1146 silane can eliminate the need for special primers in numerous bonding applications.
  • Specific systems that demonstrate improved adhesion when Dynasylan® 1146 silane is used include RTV silicones and hybrid silane­crosslinked systems.
  • Additive loading levels of 0.5 to 1.5wt.% Dynasylan® 1146 silane with regard to the overall formulation are typically recommended.
  • Dynasylan® 1146 silane can also be utilized as a mineral filler treatment.
  • The diamino and alkyl functionalities result in unique functional filler properties when Dynasylan® 1146 treated minerals are incorporated into polymers.
