CoatOSil® 1770 silane provides an improved combination of performance, appearance and handling characteristics in waterborne coatings. CoatOSil 1770 silane is shelf stable and provides the flexibility to formulate one-pack and two-pack systems. When properly formulated, crosslinking can occur under both room temperature and elevated temperature conditions.

Features & Benefits

CoatOSil 1770 silane gives waterborne coating formulation excellent properties in terms of appearance, weathering and durability:

• Improved solvent, impact and mar resistance
• Superior wet and dry adhesion
• Improved stain resistance in wood and automotive plastic coatings
• No negative effect on clarity or color of the cured film
• Excellent gloss retention upon aging

CoatOSil 1770 silane provides a range of handling characteristics that are necessary for shelf stability:

• Stability over 18 months in a fully formulated coating (one pack system)
• Stability of over 12 months for a 40% emulsion (for a two pack system)
• Stability superior to crosslinkers such as polyaziridines, melamines, isocyanates
