The two binders SILRES® M 51 E and SILRES® IC 900 by WACKER allow to formulate coatings that can withstand up to 600° C.
The Munich-based chemical company WACKER has presented SILRES® M 51 E and SILRES® IC 900, two new silicone resin binders specifically developed for manufacturing industrial coatings that can withstand high temperatures – up to 600° C – and adhere well to metallic materials such as steel or aluminium.
SILRES M 51 E is a functional methyl silicone resin finely dispersed as tiny droplets in an aqueous medium. It has been designed for formulating water-based coatings that possess exceptional chemical and mechanical strength and show excellent colour and gloss retention even after thermal stress. The resulting surface is tack-free in just fifteen minutes after application.
In addition, coatings based on SILRES M 51 E produce significantly less smoke when first heated, allowing manufacturers to formulate products that release far lower quantities of volatile organic compounds than their solvent-based counterparts. The application fields include vehicle exhaust systems, ovens and stoves, range hoods, fireplaces, pots and pans, as well as pipes and plant components for the petrochemicals industry.
SILRES IC 900, on the other hand, has been specifically designed as a binder for solvent-based paints and coatings. The product, which consists of an alkoxy-functionalised methyl phenyl silicone resin, is delivered as a pure and undiluted active ingredient. Its low viscosity also enables the development of high-solids (over 80%) coatings.
The methyl phenyl silicone resin is characterised by a molecular structure which, when crosslinked, results in a close-meshed flexible network, preventing cracks and permitting dry-film thicknesses of over 100 micrometres. The coatings based on SILRES IC 900 can be formulated as either one- or two-component products. Upon curing, they are highly resistant to chemicals and corrosion, while maintain colour stability.
