Bayhydrol eco UV 2877 is slightly based on renewable resources which helps in closing carbon loops and contribute to circular economy.

Covestro has been reportedly presenting Bayhydrol eco UV2877 at the European Coatings Show 2019 in Germany. Bayhydrol eco UV2877 is fast drying dispersion which offers impressive application flexibility in UV curing. It can be used in pigmented as well as clearcoat formulations and is ideal for primers and topcoats. Reportedly, 35 percent of the product is based on biomass.

According to the press release by Covestro, Bayhydrol eco UV2877 has a multi-curing mechanism by which coatings gain tack-free films with good mechanical properties. It provides resistance from stain before curing or low UV energy dosage. After curing, coatings attain more hardness and chemical resistance.

Dr. Berta Vega Sánchez, Marketing Manager, Furniture coatings and adhesives, Covestro, reportedly stated that the product offers 50 percent faster drying in comparison with any high-performance standard product. This product is highly beneficial for coating formulators and parts manufacturers as the coating does not need additional hardener and attains good properties in shaded areas as well, he added.

For the record, Bayhydrol coating offers design freedom to furniture manufacturers, since high-level quality cannot be attained while coating three-dimensional parts having shaded areas. One-component UV coatings are easy in handling and there is no considerable pot life.

Reportedly, no reactive thinner is required for waterborne coatings and emission of VOCs is also lower in comparison with standard systems, which makes it more suitable for labelling. The real cost advantage is when product has lower dependence on UV quality, which means that either amount of photoinitiator is reduced by coating formulators or UV dosage are reduced by processors, cite trusted sources.

Bayhydrol eco UV 2877 is slightly based on renewable resources which helps in closing carbon loops and contribute to circular economy. In a Life Cycle Assessment, significant improvements in carbon footprints have been found as compared to standard waterborne UV curable dispersions.
