3-Aminopropyl-methyl-diethoxysilane Usage And Synthesis
Uses    3-Aminopropyl-methyl-diethoxysilane acts as an adhesion promoter between inorganic materials and organic polymers, as a surface modifier and for material changes to chemical substances.
3-Aminopropyl-methyl-diethoxysilane is an important or even essential constituent in many applications. 3-Aminopropyl-methyl-diethoxysilane 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 3-AMINOPROPYL-METHYL-DIETHOXYSILANE 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.
