RESIN COMPOSITION FOR SEALER AND ITS PRODUCTION

Japanese Patent JP3550217

B2

PURPOSE: To obtain a resin composition for a sealer excellent in impregnating property to a substrate, adhesiveness, water resistance, etc., useful for surface treatment for inorganic ceramic building materials and hardly causing environmental pollution by dispersing a specific acrylic-modified epoxy resin into water.
CONSTITUTION: This resin composition is obtained by dispersing an acrylic- modified epoxy resin obtained by reacting (A) 5-90 pts.wt. acrylic resin obtained by copolymerizing (i) an aminoalkyl acrylate-based monomer of formula I [R1 is H, a halogen or a 1-5C alkyl; R2 is H or a 1-6C alkyl; R3 is H or a 1-6C alkyl; (m) is 1-6] and/or an N-aminoalkylacrylamide-based monomer of formula II [R4 is H, a halogen or a 1-5C alkyl; R5 is H or a 1-6C alkyl; R6 is H or a 1-6C alkyl; (n) is 1-6] with (ii) a polymerizable vinyl monomer with (B) 95-10 pts.wt. epoxy resin, preferably in an organic solvent at 30-120°C for 10min to 5hr and adding an acidic compound to the reaction product so that pH of at least one of amino group contained in the reaction product becomes 3-8 into water.
