Chemical Structure:


Siwin-A210 is an important or essential constituent in many applications. Siwin-A210 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 and for chemical modification

Mineral-filled composites:for pretreatrnent of fillers and pigments or as additive Synthesis of functional sillcones

The most important effects which can be achieved using Siwin-A210 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 behavior, reduction in viscosity,Newtonian behavior Higher degree of filling
