It is a low molecular weight, nonpolar, ambercolored thermoplastic resin produced from petroleum derived monomer.Characterized by its excellent resistance to acids, alkalis, good initial colorand color stability, and a good balance of flex, tear, tack, and adhesionproperties. Possesses excellent solvent release, tack, and tack retention, widesolubility and compatibility, and good resistance to oxygen and UV light.Compatible in useful proportions with styrene-butadiene rubber (SBR), rosin,modified rosins and esters, alkyds and drying oils, polar elastomers, epoxyresins, chlorinated rubber, and chlorinated paraffin.
