AQUEOUS COATING POWDER SUSPENSIONS, PREPARATION AND USE

摘要

Aqueous powder suspensions for thermoset coatings are prepared by intimately blending a mixture of (a) an epoxy resin/amine adduct having terminal amino groups, (b) a curing agent (phenolic resin, aminoplast resin, non-acidic polyester+transesterification catalyst), and, optionally, (c) a solid epoxy resin, said blend having a softening point of at least 70 DEG C., and milling down in water to a particle size of less than 20 micrometers.
