• VE-3013 may be an excellent candidate for use as a binder in precision investment casting, it also may can be used as a second backup casting coating. It cures faster than colloidal silica systems.

• In manufacture of electronics and computer components, VE-3013 can be used as a source of silicon dioxide in films deposited on silicon substrates.

• In corrosion-resistant paints, VE-3013 can be used as component in Zinc-based primer coatings.

• For manufacture of silicone sealant, VE-3013 can be used as a cross-linking age. It is also useful as a raw material in sol-gel systems.

• VE-3013 is a raw material for hard-coat with scratch-resistant character of glass or plastic lens.

• VE-3013 is used in the production of pipes and cables made of silane-crosslinked polyethylene, as a water scavenger during the production of silane-crosslinking adhesive and sealant formulations, and as co-monomers in the production of silane-modified binders for surface coatings.
