This study focuses on developing a polymer that addresses key needs for paint and primer in one exterior coatings, such as dirt pick-up resistance (DPUR), leaching resistance, early rain resistance, gloss retention, grain crack resistance, adhesion, efflorescence resistance, and tannin blocking. The outcome of the study is a polymer that is designed to withstand the exterior elements in formulations featuring <25 g/l volatile organic compounds (VOC).
LUMIFLON® FEVE powder resins have been introduced by AGC Chemicals Americas, Inc. Designed to provide weatherability, corrosion resistance, and environmental benefits when used in exterior architectural coatings applications, the resins do not require a solvent and can be used in formulations to meet AAMA 2605 specifications.

Moisture Barrier Coating
Cortec® has developed EcoShield® Barrier Coating, a waterborne moisture-barrier coating that provides nontoxic, effective, environmentally friendly paper and corrugated-board alternatives to wax and polyethylene papers. By applying the coating onto Kraft or recycled paper or linerboard, manufacturers can produce fully recyclable, repulpable paper and boxes. For more, visit www.cortecvci.com.
