Acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers), as a surface modifier and for chemical modification of substances. Is a colorless to yellowish liquid with an amine-like odour. Used in paints and coatings as additive and primer for improving adhesion to the substrate, and as metal primers. DYNASYLAN 1126 contains primary and secondary aminoalkylethoxysilanes Examples of suitable inorganic substrates are glass, glass fibres, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminium hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals. Examples of suitable polymers are epoxy resins, polyurethanes, phenolic resins, furane resins, melamine resins, PA, PBT, PC, PEK, PE, EVA, PP, PVB, PVAC, PVC, acrylates and silicones. The secondary amino group in DYNASYLAN 1126 provides high basicity at somewhat lower reactivity compared to the primary amino groups. This is of major advantage in e.g. adhesives and sealants where the silane is added to the polymer matrix: Homogeneous distribution and bonding/networking of DYNASYLAN 1126 to the inorganic filler can commence unless bonding to organic materials (e.g. polymers) will proceed. Excellent crosslinking properties make DYNASYLAN 1126 a preferred component in the silylation of inorganic filler surfaces and in corrosion-resistant primer systems for metal pretreatment. Moreover, DYNASYLAN 1126 can be used as a component in aqueous PA- and PU-sizes for glass fibers. The most important effects which can be achieved using DYNASYLAN 1126 are improvement in product properties, such as adhesion, mechanical properties, for example flexural strength, tensile strength, impact strength and modulus of elasticity moisture and corrosion resistance electrical properties, for example dielectric constant, volume resistivity and improvements in processing properties, such as better filler dispersion rheological behaviour: reduction in viscosity, Newtonian behaviour higher degree of filling. Aminofunctional silane. Used in paints and coatings as additive and primer for improving adhesion to the substrate, and as metal primers. Acts as an adhesion promoter, as a surface modifier or a crosslinking agent. Improves mechanical and electrical properties, moisture and corrosion resistance. Offers better filler dispersion and rheological behaviour.
