Session 7: Radiation Curing
Coatings industry is making progress in green technology by using bio based pigments in low VOC colorants. Water based coatings using such colorants have already made strong foothold in the architectural applications. Then there are dissolver dispersible pigments requiring minimal energy to achieve optimum color. Progress has been slow in the industrial and other areas. Now that low VOC colorants that are UV curable offer another option to reduce solvent emissions, and quick curing process reducing energy consumption. This is especially true in wood coatings market which has been slow in this change due to unavailability of colorants that meet durability and technical requirements. These new colorants are suitable for a variety of resin systems, offer advantages over UV cured water & solvent types. The film formation is quick with excellent gloss, and pigment chemistries offer exterior performance. Formulators, with this gamut of 16 colorants, now have options to match many shades to satisfy their customer needs. In addition, these colorants have excellent shelf stability, a major improvement over the previous technology which was a hindrance to popularity of such products.
