Easaqua X L 600 is the latest development to the company's Easaqua range of water-dispersible aliphatic polyisocyanates for waterborne PU coatings. According to Perstorp, the new polyisocyanate adds the advantage of higher moisture resistance to the range's benefits of easy dispersibility, fast drying, low environmental impact and broad compatibility. Perstorp says, with the best-in-class balance between low viscosity and high NCO content, Easaqua X L 600 helps meet the markets need for low VOC systems. Easaqua X L 600 is a modified polyisocyanate that offers advantages to waterborne PU coatings producers as well as the end products that their finished coatings protect. It ensures a very narrow particle size distribution after emulsification into waterborne media. Easaqua X L 600 has one of the lowest viscosities of all the products in the Easaqua range. This reduces the need for solvent in formulation and it can even be used without any solvent. As a result, Easaqua X L 600 achieves the best balance between low viscosity and functionality in the product range. In addition to its good durability, a further advantage of Easaqua X L 600 is its improvement of coating adhesion onto a wide range of substrates. Thus, it is particularly suitable for direct-to-metal (DTM) applications, coatings for automotive, transportation, plastics, flooring and general industries, says Perstorp. "What's unique about this new product is that we have been able to reduce its hydrophilicity, which in turn provides higher resistance to moisture and offers greater protection to the substrate to which the final coating is applied, says Philippe Barbeau, Innovation and Application Director of the Coatings & Adhesives markets. "We have been able to combine this high humidity resistance with the easy dispersibility and low environmental impact that our Easaqua range is known for.
