Eastman Cellulose Esters, a family of polymers, offers performance-enhancing properties for coatings. They are supplied as free-flowing powders that can be dissolved in various solvents.
Nitrocellulose is a commonly used cellulose derivative in wood coatings for its good compatibility. However, the chemistry is facing challenges for its hazardous profile and performance limitations.
Wood coatings manufacturers are currently working on developing their formulations to avoid such concerns. Cellulose Esters from Eastman can help you achieve the market demanded quality while complying with rising regulations.
Eastman Cellulose Esters functions as a main film former in lacquers. They can also be used as an additive to improve certain properties or enhance the quality of wood coatings.
Eastman Cellulose Acetate Butyrate (CABs) are highly efficient resins widely used in high-quality 2K acrylic urethanes, thermoplastics, acid curable coatings, and radiation curable systems. A variety of grades are available from Eastman. They are specifically engineered to provide or improve key attributes of the formulation. Three main variables in CAB determine the best grade for a given application: Butyryl content - Hydroxyl content - Viscosity.
Eastman Solus™ 2100 is designed with significantly lower solvent demand than nitrocellulose formulations. Nitrocellulose binders also undergoes excessive yellowing under UV light even higher than alkyd oils and isocyanates co-binders. Eastman Solus™ 2100 provides improved compatibility to alkyd resins where yellowing resistance is required. It provides faster drying time, improved gloss and excellent chemical resistance then Nitrocellulose binders.
