London - Polyurethane coatings, adhesives and composite materials are among the products that Dow Automotive and BASF will feature on their stands at this year's JEC Composites Show in Paris, 24-26 March.
Dow Automotive will focus on its polyurethane-based adhesives and PU-based and epoxy composites portfolio, together with its engineering capabilities.
The Dow Chemical Co. unit says it will present "a new milestone in joining composite materials" introducing its new two-component PU based adhesive, Betamate 2580. According to Dow, this adhesive "overcomes the limited temperature resistance of traditional PU adhesives due to a high glass transition temperature." The bonding agent is of interest in commercial transport where bonding composite materials is a major aspect, Dow Automotive said.
For BASF, one speciality for the composites business it will emphasise at the JEC show is its Relius coating systems for reconditioning wind turbines (see picture). BASF claims to be "one of the world's leading suppliers of rotor blade coatings for wind turbines," with products which offer economies, high weather resistance and excellent elongation at break.
The company is introducing an innovative elastic repair system that it says in many cases will avoid a costly exchange of blades. New, too, are its WindCoat Finish and WindCoat Protector SA coatings. BASF says the the WindCoat Protector spray coating, based on polyurethane, adheres well without use of solvents. It provides excellent adhesion to epoxy laminates and PUR Gelcoats, according to BASF.
For years the Relius Rotor Blade System has given durable protection for wind turbines, BASF said. Relius products especially suited for the glass fibre surfaces of rotor blades include gelcoat protective coatings, fillers, edge protection and top coats. The two-component coatings based on polyurethane are low in solvents or solvent-free and conform to current guidelines on VOC (volatile organic compound) content, BASF added.
