Varcum® 29358

Varcum® 29358 by Sumitomo Bakelite is a higher viscosity, general purpose, one-step liquid phenolic resin. Soluble in ketones, lower alcohols & esters with limited solubility in water. Shows good compatibility with furfural. Provides optimum and uniform wetting of the abrasive grain and powdered resin components. Varcum® 29358 is designed to be used as a wetting agent for the production of abrasive mixes for grinding wheel manufacture. The higher non-volatile content of this resin reduces the problems of wheel distortion due to the evolution of volatiles during the baking cycle.
