Why Using Dynasylan® Silanes
in Adhesives & Sealants ?
Seite 3
Dynasylan® is the Leader in
“Silanes4Adhesives” !
� Small amounts – huge effects
� dosage of only 0.1 - 2.5 wt.-% silanes is sufficient
� Dynasylan® Silanes can link, bind & protect
� crosslinking of polymers� improve bonding between inorg. fillers & organic polymers� protect sensitive products against water
� Properties can be adjusted to the customers needs
� low or high reactivity � monomeric or oligomeric� solvent or water based silanes� compatible with different polymer types / recipes…
• Aminosilanes (prim./sec.)

Dynasylan® 1189 will Speed Up the
Production of NCO-Polymers (Hybrids) …
Dynasylan® 1189 speeds up the production of silane endcapped hybrid adhesives
(Polyurethanes …) and it blocks toxic NCO-functions:
• Fast reaction with free NCO-groups, and without undesired side reactions
• Colorless and low-viscosity urethane prepolymers achievable
• High conversion of PU-end-capping
• Gains additional benefit as a “high-elastic” adhesion promoter
