dcsimg Coatings and Adhesives Raw Materials Based on Renewable Resource

Bio-based innovation

High performance enabled by nature

From automobiles to footwear, consumers are shifting to a more environmentally conscious mindset and desire more sustainable qualities in the products they use. To meet this growing demand, Covestro has developed more sustainable polyurethane coating raw materials based on renewable resources that improve the carbon footprint of manufacturers and users.

Desmodur® eco N 7300 is a new curing agent from Covestro for polyurethane coatings and made partially from biomass. Its foundation is pentamethylene diisocyanate, a revolutionary innovation in polyurethane chemistry as it is the first diisocyanate in 30 years to be fully developed and scaled-up.

With 70 percent carbon content derived from non-fossil-based inputs, Desmodur® eco N 7300 aliphatic isocyanate is the first polyurethane crosslinker to feature significant renewable content. It is on par with conventional curing agents for coatings and adhesives, and for some properties even surpasses it. Paints and adhesives formulated with Desmodur® eco N 7300 can be used in diverse applications – automotive, furniture, consumer electronics – potentially wherever HDI trimers are used.

The Impranil® eco portfolio is another new offering, this one targeted at textiles. This series of bio-based waterborne polyurethane dispersions has renewable content that reaches as high as 65 percent. With Impranil® eco it is now possible to produce coated fabrics with lower amounts of fossil-based raw materials in each layer and a better sustainability profile.

Desmodur® eco N 7300 and Impranil® eco are bio-based solutions that offer the same high performance standards of conventional products and need little reformulation efforts. The bio sources are derived from non-fossil-based inputs and do not compete directly with the food chain.
