Nitrocellulose's high flammability caused some of the worst industrial accidents in history. It also exhibits high solvent demand, especially in wood coatings. The high solvent demand translates to a high VOC level putting your products subject to rising restrictions on VOC emission.
Nitrocellulose in wood coatings exhibits a high tendency to yellowing and weathering issues, especially in outdoor applications. Nitrocellulose lacquers have limited viscosity control and poor ability to form thinner film thickness. The chemistry also allows plasticizer migration.
Eastman Solus™ performance additives are the newest Cellulose Esters designed for high-solids solvent-borne systems to meet lower VOC levels with lower solvent demand. Eastman Solus™ grades are engineered with improved compatibility towards alkyd resins commonly used in wood coating formulations. They outperform nitrocellulose in providing excellent yellowing and weathering resistance under UV light. They also provide excellent gloss, hardness development and significantly improved dry-to touch time.
