摘要:
The present invention provides fast-drying aqueous compositions that lower the cost of making roadway markings without impairing the quality or appearance of the markings made therewith. The aqueous compositions comprise one or more hollow core binder having an average particle size of from 200 to 500 nanometers (nm), preferably from 300 to 470 nm, and made of a first polymer having a glass transition temperature (Tg) of 50° C. or more and containing one or more void, the first polymer being substantially encapsulated by one or more second polymer having a Tg of −30° C. or more, preferably, −20° C. or more. Fast-drying aqueous compositions may be one component or two component compositions. One component compositions comprise one or more volatile base, one or more polyfunctional amine, and one or more hollow core binder with a second polymer chosen from, for example, an anionically stabilized emulsion polymer, a polyamine functional polymer, a polymer having strong pendant cationic groups containing and mixtures thereof. The polyfunctional amine can be part of the hollow core binder. Two component compositions comprise one or more aqueous hollow core binder and an absorber component. The present invention also provides coatings and roadway markings made from the fast-drying aqueous compositions.
摘要:
A method for improving the dirt pick-up resistance and the retention of gloss on exposure to light of a dried coating formed from a coalescent-free aqueous coating composition is provided. The coalescent-free composition composition contains an aqueous emulsion-polymerized polymeric binder having a glass transition temperature from about −35 C. to about +25 C. with from about 2% to about 20%, by weight based on the weight of the polymeric binder, of at least one copolymerized ethylenically-unsaturated active methylene monomer.

摘要:
An aqueous traffic paint including hard-soft polymer particles, polyfunctional amine, and volatile base is provided. The hard-soft polymer particles, which contain soft polymer and hard polymer, have a hydrophobicity characterized by a Hansch parameter of at least 3. Also provided is a method of producing a traffic marking on a road surface using the aqueous paint. The aqueous traffic paint is suitable for application to road surfaces, including oily road surfaces, and may be applied at temperatures below 15° C.

摘要:
The present invention provides fast dry binder compositions comprising one or more anionically stabilized emulsion polymer having a weight average particle size of from 100 to 165 nm, one or more polyamine, one or more volatile base and one or more filler, extender and/or pigment in a composition having a % PVC of from 63 to 80. The invention provides surprisingly stable fast dry binder compositions for such a high extender or filler loading and the compositions dry far faster than binders made with waterborne polymers having a larger particle size. The invention provides high performance traffic paints at a reduced cost in use and coated substrates, such as traffic markings or exterior insulation finishes (EIFS).
