COATING COMPOUND FOR ELASTOMER/METAL COMPLEX MEMBER, COATING OF SAID MEMBER AND ELASTOMER/METAL COMPLEX MEMBER COATED WITH SAID COATING COMPOUND

摘要

PURPOSE:To obtain the subject coating compound suitable as a coating film of rubber vibration insulator such as engine mounts, etc. equipped for reducing transfer of vibration of automobile engine, by blending a solution containing polyurethane with a rust preventive capable of forming a chelate with a metal. CONSTITUTION:(A) A solution containing a polyurethane prepared by reacting (i) a polyol with (ii) a polyisocyanate optionally in the presence of a chain extender is blended with (B) (iii) a rust preventive which is shown preferably by the formula and is capable of forming a chelate with a metal and (iv) rust- preventive pigment to give a coating compound for elastomer/metal complex member. Rubber vibration insulator is preferable as the complex member.
