The reaction of thermosetting acrylic resin with amino usually need to proceed in certain baking temperature(usually requires 150℃-180℃),but many light weight plastic substrates in more than 130℃ curing temperature physical deformation will happen, therefore, required to provide a relatively low temperature baking conditions(80-120℃) thermosetting resin, it could provide possibility for these coatings to be used in these plastic and other heat sensitive substrates.
Thermosetting acrylic resin SE3668 is developed to meet this demand.
