ABSTRACT:
A water-based maskant composition and a chemical milling method using the maskant composition. Said water-based maskant composition comprises 100 parts by weight (as solids) of a latex constituent consisting of (a) 5-60 parts by weight (as solids) of a copolymer latex obtained by emulsion-polymerization of a monomer mixture consisting of 30-70% by weight of an aliphatic conjugated diene compound, 20-70% by weight of an aromatic vinyl compound, 0-10% by weight of an ethylenically unsaturated carboxylic acid and 0-50% by weight of a vinyl compound copolymerizable therewith and (b) 95-40 parts by weight (as solids) of a natural rubber latex; 10-500 parts by weight of a filler; and 0.1-10 parts by weight of a thickener, wherein the vicosity at 25.degree. C. is 500-5,000 cps as measured by BH type rotor at 20 rpm at a solids concentration of 50% by weight, the pH is 7-9 and the tensile strength and elongation of a film obtained from the composition are 50-150 kgf/cm.sup.2 and 100-800%, respectively, as measured according to JIS K 6301.
