SiSiB® PC1120 is an important or even essential constituent in many applications. SiSiB® PC1120 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 PC1120 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
