Phthalamide → Hexanediamide

Participants

Reaction Steps

A series of films were prepared using these above four bisamides at an equivalent molar replacement, that is, normalizing to the molecular weights of 396.5, 432.6 and 376.5 for the phthalamide, sebacamide and adipamide replacements of 390.5 m.w. hexamethoxymethyl-melamine. Removal of 1.5 g melamine from a nominal ten g solids formulation therefore resulted in replacement by 1.52 g iso- or terephthalamide, 1.66 g sebacamide and 1.43 g adipamide. Removal of drawn films after curing for 20 minutes at 300° F. as described above allowed the following dynamic mechanical analysis of crosslinking as described in Journal of Coatings Technology, 46, no. 808, 29-42 (1992) by L. W. Hill in the article `Structure/Property Relationships of Thermoset Coatings.
