Reilly™ PDHP Adhesive Accelerator

Reilly™ PDHP Adhesive Accelerator

High purity PDHP (dihydrophenylpyridine), is an accelerator for second generation acrylic adhesives (SGA’s), also known as reactive acrylics or tough acrylics.

Second generation acrylic adhesives are excellent at bonding unprepared or oily metals with fixture times of one to several minutes. They are exceptionally tough, with high impact and peel strengths. SGA’s are formed by toughening a methyl methacrylate based adhesive using a chlorosulfonated polyethylene rubber. The rubber is dissolved in methacrylate monomer along with a peroxide or hydroperoxide initiator, and then cured with an activator containing a dihydropyridine.

Reilly PDHP Adhesive Activator is a purified form containing over 80% of the active dihydropyridine, which offers significant improvements in cure times and coloration versus other crude mixtures with lower purity.
