Reactivity:

VANABIO® PC1120 is a bifunctional organic compound in which the silicon-functional OC2H5 -groups hydrolyze in the presence of water to give ethanol and the corresponding reactive silanols, which can be bonded to an inorganic substrate; the organophilic amino group can interact with a suitable polymer.


The hydrolysis of VANABIO® PC1120 takes place autocatalytically in a short time of about 5-10 minutes. Hydrolysates having a concentration of < 5% are stable for more than 72 hours. The pH is about 11.


Examples of suitable inorganic substrates are glass, glass fibres, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica; also suitable are aluminium hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.


Examples of suitable polymers are epoxy resins, polyurethanes, phenolic resins, furane resins, melamine resins, PA, PBT, PC, PEK, PE, EVA, PP, PVB, PVAC, PVC, acrylates and silicone.


VANABIO® PC1120 can undergo reactions with ketones or esters as solvents. Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates resp. carbamates. Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (for example isocyanates, epoxides, etc.) or by co-condensation with polysiloxanes.


Application


  • VANABIO® PC1120 silane coupling agent is an important or even essential constituent in many applications. VANABIO® 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 silicone 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


Packing and Storage


  • VANABIO® PC1120 is supplied in 180Kg steel drum or 900Kg IBC container.


  • In the unopened original container VANABIO® PC1120 has a shelf life of one year in a dry and cool place.
