Product description

Picco™ A-120 hydrocarbon resin is a low molecular weight, amber colored thermoplastic resin produced from petroleum-derived monomers that is polymerized under conditions that control its softening point within a narrow range. Being non-polar, it is characterized by its excellent resistance to acids, alkalis and moisture and is extremely water repellent. It shows good color stability and, when formulated with elastomers, a good balance of flex, tear, tack and adhesion properties. In addition, Picco A-120 has excellent solvent release, tack and tack retention, wide solubility and compatibility, good resistance to oxygen and UV light, provides excellent pigment wetting and can be used with both reinforcing and non-reinforcing fillers.</br></br></br></br></br> Picco A-120 is a viscous fluid at rubber-milling temperatures, and aids compounding by reducing viscosity and by adding tack while on the rolls. These advantages, combined with improvement in mold flow during cure, are obtained without lowering the cured hardness of the finished product. This resin is particularly indicated as a processing and reinforcing agent in rubber compounds and as a binder in protective coatings. In styrenic block copolymer-based adhesives Picco A-120 preferentially associates with the styrenic end blocks, producing higher cohesion at temperatures up to 70°C without affecting tack and adhesion properties. Picco A-120 is also utilized frequently in EVA-based woodworking adhesives.
