Applications

High purity GP-221-HP dihydrophenylpyridine (PDHP), is an amine-aldehyde accelerator for adhesives and sealants. The high assay of GP-221-HP dihydrophenylpyridine (PDHP) (87 to 92 percent pure) gives the following benefits:
• Much higher and consistent bond strengths;
• Very low odor;
• Very low color, leading to colorless bond lines;
• High stability in monomers, thus allowing the formulation of stable two-part systems;
• Non-slip systems – does not contain oily impurities, which cause the adhesive to slip or “skate” across the surface of the activator;
• Very low residual aniline content (less than 0.05 percent), which allows it to meet strict new European safety directives.

Packaging

55 gallon Blue Poly Drum, net weight: 200 Kg.

Storage and handling guidelines

Keep container tightly closed in a dry and well-ventilated place, store at ambient Temperature. Shelf-life: 2 years.
