Reichhold (Research Triangle Park, N.C.) has introduced POLYLITE 32245, a new line of low-viscosity, low-styrene (less than 35 percent) casting resins formulated as alternatives to orthophthalic-based resins used in engineered marble applications, such as integral bowl vanities, wall panels, shower pans and bathtubs.

Reichhold (Research Triangle Park, N.C.) has introduced POLYLITE 32245, a new line of low-viscosity, low-styrene (less than 35 percent) casting resins formulated as alternatives to orthophthalic-based resins used in engineered marble applications, such as integral bowl vanities, wall panels, shower pans and bathtubs. This medium-reactivity resin line’s low viscosity reportedly allows higher filler loadings than conventional casting resins, thus reducing part material costs, and is formulated for use with lightweight fillers and carbonates. The resins are prepromoted for room temperature cure, using methyl ethyl ketone peroxide (MEKP). According to the manufacturer, initial tests have demonstrated 2 to 3 percent resin savings, independent of filler type.
