Sealing fiber reinforced plastics. |
摘要 |
<p>High solids thermosetting organic solvent solution coating compositions are disclosed which are particularly useful for sealing the pores in fiber reinforced plastics. These compositions contain a mixture of resins comprising (1) from 30% to 70% of one or more hydroxy functional resins having a number average molecular weight of at least about 700, a Gardner bubble viscosity less than about Z<Sub>4</Sub> measured in methyl ethyl ketone at 90% solids at 25'C., and at least 5% of the hydroxy groups thereof being primary hydroxy groups, (2) from 10% to 70% of low molecular weight epoxy ester made by esterifying one or more resinous polyepoxides having a 1,2-epoxy equivalency of at least 1.2 with an approximately stoichiometric proportion of monocarboxylic fatty acid to provide an essentially epoxy-free ester having a Gardner bubble viscosity less than Z<Sub>4</Sub> at 75% solids in xylol at 25°C., and (3) the balance of the mixture, but not less than 15% thereof, being a curing agent having a plurality of groups reactive with the hydroxy groups in the hydroxy resin and in the epoxy ester</p> |
