Perstorp to present ‘green' PU technologies at Chinacoat 2010

Tolonate used to formulate polyurethane coatings, with exceptional durability, chemical resistance and mechanical properties. This product line includes some fast drying grades, and low viscosity products to provide better productivity of the painting process.Easaqua (previously Rhodocoat) self-emulsifiable polyisocyanates, used as crosslinkers in waterborne polyurethanes that provide effective and "greener" alternatives to solvent-based coatingsCapa polycaprolactones, which reduce the need for solvents thanks to their low viscosity, while giving good flexibility at low temperature and abrasion resistance to polyurethane formulations. Recent tests showed that PUDs using Capa are more durable than the ones based on adipate polyesters, according to Perstorp.Boltorn W3000, a high molecular weight amphiphilic, air-drying resin with good dispersing and surfactant properties. An addition rate of under 2 % of Boltorn W3000 to a solvent-based alkyd paint formulation allows up to approximately 15 % of water to be added to it, enabling a reduction in VOC content and reducing the environmental impact of the formulation as well as its cost.The company's plans also include a capacity expansion for isocyanates, with the first additional volumes available in 2012, and the doubling of the production capacity of its caprolactone range.
