Product Description
Technicure® TDU-20 is an aromatic substituted urea based accelerator [1,1'-(4 methyl-mphenylene) bis(3,3 dimethyl urea)] for use as an accelerator for dicyandiamide (DICY) to produce shelf-stable one-part systems. Technicure TDU-20 is an excellent accelerator for adhesives, powder coatings, prepregs, films and reinforcements. At levels of 3phr, gel times of less than 8 minutes at 120C and less than 5 minutes at 150C when used with approximately 8 phr of DICY and bisphenol A epoxy resin, EEW 190. DSC onset is 122C Tg's approaching 120 are easily obtained.
