PENTALYN A synthetic resin, a hard, pale, thermoplastic resin, is the pentaerythritol (PE) ester of refined rosin. Compared with rosin esters derived from glycerol, this PE ester is a larger molecule and has about a 20°C higher softening point and greater heat stability. When adducted to obtain still higher softening point resins, lesser amounts of modifying agents are required to yield a resin of equivalent softening point. Uses for PENTALYN A synthetic resin include protective coating vehicles, adhesives, and printing inks.
Hard, resinous; high refractive index; good stability to heat, light, and moisture; wide solvency; low solution viscosities; excellent gloss; excellent pigment wetting properties.
Compatible in practically useful proportions, with raw, cooked, and blown drying oils; alkyd resins; ester type and hydrocarbon waxes; natural, synthetic, chlorinated rubber and reclaimed rubbers. Limited compatibility with nitrocellulose and ethylcellulose. Incompatible with cellulose acetate.
