USE & PERFORMANCE
Outstanding properties: Provides very light color, along with excellent oxidative stability. Color
stability and excellent peel and tack properties. Low odor and volatility. Improved strength and
water resistance. Heat resistance, and wide compatibility and solubility. Excellent balance of tack
and adhesive and cohesive properties. Excellent balance of shear strength and adhesive and cohe-
sive properties. Tack retention. UV stability. Excellent resistance to acids, alkalis, and moisture.
Recommended for polymers: styrene phase of SBCs, EVAs blended with other rosin esters or AMS
phenolics, paraffin, microcrystalline, FT and PE wax, natural and synthetic rubbers, low vinyl-ace-
tate concentration EVA copolymers, SIS block copolymers, amorphous poly-alpha olefins, paraf-
fin, microcrystalline waxes, amorphous PP, SBS, APO rubber, terpene resins, rosin and modified
rosins, rosin esters, paraffin and microcrystalline waxes, coumarone-indene resins, linseed, soy-
bean and mineral oils, the polystyrene portions of styrenic block copolymers, acrylic, polyester,
epoxy resins, and chlorinated rubber, medium and long drying oils. Not compatible with all grades
of these polymers at all ratios.
Recommended for products: adhesives for packaging, bookbinding, nonwovens, and assembly
applications, woodworking, PSAs for tapes and labels, building and construction, automotive
refinish, laminating, sealants, caulks, footwear and leather, graphic arts, printing inks, paint and
varnish, lithographic (cold set) inks, and concrete curing compounds
