Chemical Structure

Introduction

SiSiB® PC1200 (equal to A-1120, GF 91, KBM603) is a clear, colorless, strongly alkaline liquid with smell being very sensitive to hydrolysis. The chloride content ranges in the lower ppm-level.

SiSiB® PC1200 is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or silicone-polymers or as crosslinker (moisture crosslinking of polymers). The application as "coupling agent" leads in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.

Solubility: SiSiB® PC1200 is unlimited miscible with water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir PC1200 into water. With alcohols miscibility is, in general, possible with self-catalyzed exchange of the alkoxy-groups. In aliphatic and aromatic hydrocarbons and (moisture-free!) ethers or esters SiSiB® PC1200 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates PC1200 shows typical amine function. Some nonferrous metals can discolor upon contact.

Applications

SiSiB® PC1200 may be used as an effective coupling agent for clay reinforced elastomers such as natural and nitrile rubber, to improve physical and dynamic properties.

SiSiB® PC1200 may be used as an effective coupling agent for mineral reinforced nylon 6, nylon 6/6 and polybutyleneterephthalate, to increase the flexural and tensile strength of the thermoplastic composite.

SiSiB® PC1200 may be used as a fiberglass finish or a resinous additive for fiberglass reinforced phenolic, melamine and expoxy thermoset composites.

SiSiB® PC1200 may be used as a mineral binders in in foundry and abrasive composite applications, to improve adhesion, increase composite strength.

SiSiB® PC1200 may be used as a glass and metal primer, to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces.

SiSiB® PC1200 may be used as an adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two part urethane and epoxy adhesives and sealants.
