BayerMaterialScience LLC says it has developed a new generation of waterborne polyurethane coatings for bridge structures that offer the performance of traditional solvent-bornes.
The new formulations were introduced in October at the North American Coatings Show in a presentation called presented “Environmentally Friendly Graffiti Resistant Coatings: Waterborne Polyurethane Coatings for Bridge Structures that Actually Work.”
The coatings are suitable for concrete beams, columns and abutments and can also protect glass or plastic windbreaks, transit structures or support structures, according to BayerMaterialScience.
Performance and Features
The company says the two-component (2K) waterborne resin systems have no odor and provide durability and graffiti, abrasion and chemical resistance in a near-zero VOC formulation.
Gloss levels can be adjusted, from high gloss to matte, without using flattening agents, and the coating can be used as a topcoat for other primers and midcoats, the company says.
“These coatings demonstrate that applicators can choose a more sustainable coating option without having to sacrifice performance and durability,” said Steven Reinstadtler, the company’s market development manager - Construction and Green Building Initiative.
A company spokeswoman was unable to say Monday (Nov. 8) which companies are manufacturing the coatings.
Bayer MaterialScience LLC, a producer of polymers and high-performance plastics in North America, is part of the global Bayer MaterialScience business with approximately 14,300 employees at 30 production sites around the world.
