MOSCOW (MRC) -- Solvay launched today Reactsurf 2490, a new APE-free polymerizable surfactant designed as a primary emulsifier for acrylic, vinyl-acrylic and styrene-acrylic latex systems, said Coatingworld.
Reactsurf 2490 improves emulsion performance to deliver superior functional and aesthetic benefits in exterior coatings and pressure sensitive adhesives (PSAs), compared to conventional surfactants, even at high temperatures.
In addition to exterior coatings and pressure sensitive adhesives, other common uses of Reactsurf® 2490 include paint binders, adhesives & sealants, textile & nonwoven binders, paper coatings, and building & construction applications.
“Exterior coatings and pressure sensitive adhesives are both prone to surfactant leaching,” explains Janice Ng, Coatings Asia Pacific Business Development Manager. “In exterior coatings exposed to harsh environmental conditions, leaching leads to dirt pick-up and water marks, while it leads to water whitening in PSAs. Reactsurf® 2490 prevents surfactant migration, which improves water-whitening resistance for PSAs and dirt pick-up resistance for exterior coatings. This means clear label products retain their original appearance, and exterior surfaces remain clean and dirt free."
We remind, Solvay and Orbia recently announced their entry into a joint venture framework agreement to create a partnership for the production of suspension-grade polyvinylidene fluoride (PVDF), creating the largest capacity in North Americam said the company. As it is further stated in a press release, the joint venture will create the largest PVDF production facility for battery materials in the region. The total investment is estimated around 850 million USD, partially funded by a grant to Solvay from the U.S. Department of Energy for a total of 178 million USD.
