PURPOSE:To obtain a paint compsn. which gives a coating film having excellent initial hardness and tack-freeness after drying at low temp., by blending a room temperature curing alkyd resin with a short-oil alkyd resin or an acrylic resin and an amino resin. CONSTITUTION:A paint compsn. is obtd. by blending 100pts.wt. room temperature curing alkyd resin with 10-100pts.wt. short-oil alkyd resin or acrylic resin and 10-100pts.wt. amino resin or acrylic resin and 1-50pts.wt. amino resin. As the alkyl resin, an oxidative polymn. type modified alkyd resin is generally used and alkyd resins modified with a phenolic resin, an epoxy resin, an acrylic resin or a urethane resin, etc. can also be used. As the amino resin, low- temperature crosslinking melamines such as methylolmelamine are preferred. |
