Abstract

The effect of a low molecular weight additive in acrylic-melamine resin on its curing behaviour was studied by Dynamic Spring Analysis. Dioctyl Phthalate (DOP) was selected as an additive and its content in acrylic-melamine resin was varied.
The following results were obtained.
1) The curing behaviour of resin varied as a function of DOP content. The maximum curing velocity was obtained at most suitable DOP content.
2) DOP was considered not to effect the curing mechanism but to decrease the viscosity of resin. This indicates that the probability of collision of functional-groups increased and the curing velocity was promoted by the addition of DOP.
