Product Details

Hydrophobic Dynasylan® 1146 diaminofunctional silane is used in adhesives and sealants, and in coatings, to improve the adhesion of amino-reactive resins (e.g. RTV-silicones, two-part urethanes, silylated urethanes, MS polymers, and two-part epoxies) to inorganic surfaces, plastic surfaces, and inorganic fillers.
 
Dynasylan® 1146 silane is characterized by randomly distributed linear and cyclic oligosiloxanes and it fulfills 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.

Benefits

  • For SMP’s, RTV-1, 1K Alkoxy / 1K Oxime Silicones
  • Low VOC, low color, improved mechanical properties, water resistance, low yellowing

Typical Applications

Dynasylan® 1146 silane is a versatile product that provides improved product performance and quality. It 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 adhesives and sealants, and in coatings applications. When used as an additive, it 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 silane-crosslinked systems. Additive loading levels of 0.5 to 1.5 wt.% Dynasylan® 1146 silane with regard to the overall formulation are typically recommended.
 
It 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.
