Abstract
A two-component aqueous composition for thick horizontal markings on roads or other traffic areas is disclosed. One component includes a drying-accelerated binder, pigments, pulverulent fillers and additives, while the other component includes coarse fillers. The composition is very high solids and fast drying without the cracking, smearing, and dirt adhesion typical of thick film traffic markings.
Claims14
An aqueous marking composition, comprising:
- (1) 40 to 60% by weight, based on the total weight of said marking composition,
- (a) drying-accelerated binder;
- (b) color pigments;
- (c) pulverulent fillers;
- and
- (d) additives;
- and
- (2) 60 to 40% by weight, based on the total weight of said marking composition, of coarse fillers whose particle diameter is at least 100 m, wherein said drying-accelerated binder comprises:
- (a) an anionically stabilized emulsion polymer;
- (b) a polyfunctional amine;
- and
- (c) a volatile amine,
- and wherein said aqueous marking composition has a solids content of 87 to 93% by weight, based on the total weight of said aqueous marking composition.
