Wacker Silres® H44 Silicone Resin
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Product description: SILRES® H44 is a powdered silicone resin with excellent solubility in various organic solvents and good compatibility with organic resins. Special features: solvent-free, solid phenylmethyl polysiloxane resin high solubility in organic solvents fast curing in the presence of catalysts excellent heat stability Application: SILRES® H44 is preferably used as binder for the socket cement of high-temperature incandescent lamps. Due to its short curing time, SILRES® H44 is highly suitable for automated production lines. SILRES® H44 can also be added to socket cements based on organic binders in order to enhance their moisture resistance. A quantity of about 5% is usually enough to considerably reduce the level of water absorbed by such cements. Information provided by Wacker Chemie AG.
