Versatile Product Could Make Stained and Yellowed Concrete Coatings a Thing of the Past
October 28, 2004 Lehigh Valley, Pa.
Epoxy coating formulators preferring a low color, stain resistant top coat with good handling properties need to search no further than AnquawhiteTM 100 curing agent, Air Products' (NYSE: APD) latest waterborne epoxy curing agent. Anquawhite 100 curing agent, a polymeric amine dispersion in water, is being introduced to the North American market this week at the International Coatings Expo being held October 27-29 at McCormick Place North in Chicago, Ill.
"This novel product is really flexible in terms of formulation capability," said Dave Dubowik, principal application chemist for Air Products. "It is very attractive to customers because of its fast dry, long working life, high stain resistance and resistance to yellowing."
Anquawhite 100 curing agent is a novel waterborne curing agent dispersion designed for use in ambient or heat cure two part epoxy systems. The epoxy curing agent market applications include wall and floor coatings, metals coatings for bulk tanks and railcars, and also institutional or heavy duty maintenance coatings. Anquawhite 100 curing agent can be formulated with a variety of epoxy resins and waterborne epoxy dispersions while maintaining VOC (volatile organic compound) levels <100 g/l. Anquawhite 100 curing agent, due to its dispersion nature, can be formulated to high solids while maintaining low viscosity and fast dry.
Anquawhite 100 curing agent has been benchmarked for chemical spot and stain resistance against established water-based epoxy technology. In these studies Anquawhite 100 curing agent offered marked improvements in acid and food stain resistance. Anquawhite 100 based coatingsremained intact upon sulphuric acid or acetic acid exposure, whereas other water-based systems showed severe failures. Anquawhite 100 curing agent based coatings also exhibited very high resistance to common food stains such as coffee and mustard while typical water-based epoxies were badly stained.
"Customers will be very pleased with its ease of handling and application. It can be applied in high traffic areas or heavily used areas without area shutdown because it is waterborne with low odor. This product is a great choice for 'institutional' or 'housing' environments for its ability to be used with clear or pigmented topcoats, and longer-term, it has very good water resistance, and acid and food staining resistance," Dubowik said.
Performance advantages for Anquawhite 100 curing agent include its formulating versatility, long pot life, fast dry and low VOC, high gloss, stain resistance, yellowing resistance, hot tire pick up resistance, and freeze, thaw stability.
