ONE-COMPONENT SYSTEM BASED ON COREACTIVE LATICES AND CAPABLE OF FORMING COATING MATERIAL CROSSLINKABLE AT ROOM TEMPERATURE AND USE THEREOF IN COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a one-component system which has a good storage stability and can form a low-temp.-crosslinkable coating material and to provide the use thereof. ;SOLUTION: This system is based on a water-base dispersion which contains 10-30 wt.% at least two coreactive polymers comprising 2-98 wt.% polymer (A) having optionally masked aldehyde groups, 2-98 wt.% polymer (B) having acetoacetoxyethyl groups, and 0-50 wt.% polymer (C) which is nonreactive with both polymers A and B and is prepd. by the free-radical polymn. of at least one neutral monomer selected from among (meth)acrylates, vinyl monomers, styrene, and derivs. thereof in water-base emulsion.;COPYRIGHT: (C)1998,JPO
