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:
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.
