3-Aminopropyl-methyl-diethoxysilane / 3-Aminopropylmethyldiethoxysilane

Countertype of Dynasylan 1505, DowCorning Z-6015, DP-A210, KH-902

Chemical Structure

Introduction

gamma-Aminopropylmethyldiethoxysilane acts as an adhesion promoter between inorganic materials and organic polymers, as a surface modifier and for material changes to chemical substances.

Typical Physical Properties

Applications

gamma-Aminopropylmethyldiethoxysilane is an important or even essential constituent in many applications. It is particularly important as an additive to cold-curing phenolic and furan foundry resins to improve the flexural strength of sand/resin elements with very long shelf life of the resins.

Further examples are:
Glass fiber/glass fabric composites: as size constituent or finish
Glass and metal primers
Abrasives: as additive to phenolic resin binders
Sealants and adhesives: as primer or additive and for chemical modification
Mineral-filled composites: for pretreatment of fillers and pigments or as additive
Synthesis of functional silicones

The most important effects which can be achieved using KH-902 are improvements 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 behavior: reduction in viscosity, Newtonian behaviour;
Higher degree of filling.
