Zusammenfassung: | PURPOSE:A latex composition suitable for an adhesive for carpet backing, having a little change of viscosity with time, improved blister resistance and adhesiveness, obtained by synthetic rubber latex with a specific amount of an organic polysiloxane compound having a specified cloud point. CONSTITUTION:100pts.wt. solid content of synthetic rubber latex (e.g., copolymer emulsion comprising styrene butadiene, etc., as a main component) or blended with (A) 0.01-5pts.wt., preferably 0.1-2pts.wt. organic polysiloxane compound having 55-80 deg.C cloud point and (B) 0.1-5pts.wt. aromatic sulfonic acid formalin condensate salt (e.g., salt of flrmalin condensate of naphthalenesulfonic acid, etc.,). |
