Phosphate monomers were used at a level of 1, 2, and 4% BOTM, respectively, to compare with the control that did not contain any phosphate monomer.
A wet adhesion improvement from 0B to 5B was obtained in the paint with 3% BOTM phosphate monomer on the aluminum substrate and with only 1% BOTM of the same monomer on the zinc phosphate-treated steel substrate.
Up to 4% BOTM of PAM-100 and 10% of PAM-200 were successfully incorporated into the polyol systems without difficulty.
The molecular weight did increase slightly when the phosphate monomers were used but it was not significant, even at 4% BOTM level.
The Japanese group noted it will cover the purchase price with a mix of cash on hand and fully-committed financing from The Bank of Tokyo-Mitsubishi UFJ (BoTM).
According to Reuters' sources, Mizuho Bank and Sumitomo Mitsui Banking Corp have already been approached to possibly refinance BoTM's bridge loan.
