AOC delivers color technologies IN EFFORTS to improve performance, aesthetics and processability of cast polymer products AOC has created new Vicast® resin, Vibrin® gel-coat and Chroma-Tek® colorant products. Vicast A540-DHA-15 casting resin is said to offer the combination of improved green strength and reduced colour. It is said to allow a single resin to be used for both cultured marble and onyx end-products. The product can also be used in flat or contoured moulds to make small or large parts. Applications for Vicast A540DHA-15 include bath fixtures, shower pans and walls. Vibrin G425AA clear gelcoat is said to provide cure benefits for the cast polymer
manufacturer and outstanding resistance to moisture. It has a 100% NPG base for moisture resistance. A 48% styrene gelcoat, it is typically sprayapplied to the mould to provide a protective surface to cultured marble and onyx products. AOC expects this product to sell well to manufacturers of sinks, baths, shower components and other products exposed to water. Chroma-Tek CT-10866 pigment dispersion is a more affordable version of the popular white used for automatic casting equipment. The high strength dispersion is also said to offer ease of processing in hand-mixing operations. AOC; tel: +1-901-854-2847; website: www.aoc-resins.com. March 2004
