Super fast curing silver mirror back top coating

The invention relates to a primer base for the back of ultra fast curing glasses, the components of which by weight percentages are respectively: 35 percent to 50 percent of propyl modified resin mixed solution, 8 percent to 15 percent of crosslinking resin, 17 percent to 20 percent of pigment, 2 percent to 5 percent of promoter and 15 percent to 17 percent of solvents. The materials are mixed and stirred evenly, thus obtaining the finished product of the primer base for the back of the glasses. The primer base for the back of the glasses prepared by the invention takes the propyl modified resin as a basic film forming substance and adopts part of methyl-etherified formaldehyde resin as the crosslinking resin and the extender pigment, the pigment, the promoter and the various mixed solvents are added, so that the primer base after film forming has level and smooth surface, good adhesion, proper degree of hardness and brittleness, improved water and chemical resistance, excellent moisture and heat resistance and salt-mist resistance and especially obviously improved xylene wiping resistance and CASS resistance. During the process of application, curtain coating is stable, does not branch off and is totally dried during 6 minutes to 10 minutes of curing process at the temperature of 130 DEG C to 140 DEG C.
