Abstract
PURPOSE: To prevent the water absorption of foamed polystyrene which results in the loss of heat insulation thereof, by coating the surface of a foamed polystyrene with a coating composition composed of a specific paraffin wax and an ethylene- venyl acetate copolymer.
CONSTITUTION: A foamed polystyrene molded article is coated with a coating composition composed of 70W85% of a paraffin wax containing ≤80% of n-paraffins, and having a melting point of≥65°C, and 30W15% of an ethylene-vinyl acetate copolymer having a molecular weight of 15000W16000. the coating is carried out by melting the composition at 100W130°C and applying to the surface by brushing, dipping or spraying.
