UV-Curable Powder Coatings: Benefits and Performance
UCB has developed two UvecoatTM powder coating resins specifically for wood composite substrates such as medium-density fiberboard (MDF). The use of UvecoatTM 1000 as a primer-surfacer can reduce the number of coating layers and, when combined with liquid topcoats, provide an excellent finish. The use of UvecoatTM 1100 in a one-coat textured coating produces an outstanding finish with good surface qualities that has proven to be an attractive method to coat furniture and wall panels.
UCB has also developed the UvecoatTM 2000 series resins for metal applications. Requirements for conventional powder coatings on metal substrates are well known. Evaluations of Uvecoat 2000 series resins have shown that UV-curable powder coatings perform very well on different types of metal substrates. UV-cured powder coatings exhibit good adhesion and film flexibility, and protect properly pre-treated substrates against corrosion. They also exhibit good to excellent weathering resistance when evaluated using accelerated and natural weathering conditions.
