Study on Physical Property of Melamine-Alkyd Resin Films (Report III)

Effect of the difference between melamine resins and benzoguanamine resins upon physical property

Abstract

Study was made on viscoelastic property of melamine resin or benzoguanamine resin and oil-modified alkyd resin. Benzoguanamine resin-alkyd resin system had a little crosslinking density and formed no plateau part in a high temperature elastic domain, but when a part of benzoguanamine resin was replaced by melamine resin, a plateau part was found in that domain.
From the above, it was found that melamine resin has a larger cross-linking tendency to alkyd resin than benzoguanamine resin, and the resulted system has more densely cross-linked structure.
