     Product Description

Piccolastic A75 hydrocarbon resin is a low molecular weight, light colored, nonpolar, hydrocarbon resin derived from pure styrene monomer. Indicated for use in adhesives, coatings, plastics modification and rubber compounding, particularly as primary plasticizers and softeners. Piccolastic A75 can be used as a modifier for rubber and plastic compounds used in shoe construction and as a binder for xerographic toners. In styrenic block copolymer-based systems Piccolastic A75 associates strongly with the styrene endblocks, reducing melt viscosity and cohesion without greatly affecting tack and adhesion properties. Piccolastic A75 is compatible with EVA grades with up to 20% vinyl acetate and will improve low temperature flexibility and reduce the melt viscosity of the system. Piccolastic A75 complies with many FDA regulations for applications involving direct contact with food. Compliance with a given regulation in a specific situation should be verified prior to use in a food contacting application.
