Applications & Uses

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.
