The dual nature of its reactivity allows DYNASYLAN® 1189 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics and elastomers) thus functioning as an adhesion promoter or as a surface modifier. DYNASYLAN® 1189 is a colorless liquid with a slight amine-like odor which soluble in alcohols, and aliphatic or aromatic hydrocarbons. DYNASYLAN® 1189 may be used with such polymers as epoxy, polyurethanes, PA, PBT, EVA, modified PP and silicones. It is used as a primer and additive for improving the adhesion of paints and coatings to the substrate. The most important product effects that can be achieved using DYNASYLAN® 1189 include improved adhesion, improved mechanical properties, e.g. flexural strength, tensile strength, impact strength and modulus of elasticity, improved moisture and corrosion resistance. DYNASYLAN® 1189 can also provide improvements in processing properties, such as rheological behavior: reduction in viscosity, Newtonian behavior. Bifunctional silane. Used in paints and coatings. Offers improved adhesion and improved mechanical properties, e.g. flexural strength, tensile strength. Provides impact strength and modulus of elasticity. Exhibits improved moisture and corrosion resistance.
