Covestro boosts furniture coating efficiency
Rapid UV curing even in shaded areas
The furniture market is growing worldwide. In light of the intense competition, manufacturers are facing increasing pressure to react more flexibly and shorten lead times. This is also true for industrial furniture and parquet coating, where there is a constant need to balance speed and quality.
At the 2017 European Coatings Show, Covestro is presenting Bayhydrol® UV 2877, a new, fast-curing dispersion offering great flexibility when used in UV curing, one- and two-component coating systems. It can be used in both pigmented and clearcoat formulations, and is equally suitable for both topcoats and primers.
Significantly higher productivity
“Drying is up to 50 percent faster than with a high-performance standard product,” said Dr. Berta Vega Sánchez, marketing manager for furniture coatings and adhesives at Covestro. “The coating achieves good properties even in shaded areas without the need to add an additional hardener, which is equally beneficial to coating formulators and parts manufacturers.”
Furniture manufacturers gain design freedom, since three-dimensional parts with shaded areas can be coated to a high level of quality. One-component UV coatings are easy to handle, there is no pot life to consider and there is less waste than with standard systems.
The waterborne coatings require no reactive thinner and emit lower amounts of volatile organic compounds (VOC) than standard systems, allowing for more favorable labeling. The lower dependence on UV quality means that either processors can reduce the UV dosage or coatings formulators can reduce the amount of photo initiator, which is a real cost advantage.
Coating formulations with Bayhydrol® UV 2877 have a dual curing mechanism: In the first step, self-crosslinking occurs while the coating releases water. This results in tack-free coating films with good mechanical properties and stain resistance even before UV curing. Subsequent curing with UV radiation gives the coatings their chemical resistance and hardness.
