Eastman Cellulose Acetate Butyrate (CAB-551-0.01, Food Contact) has many unique attributes that will serve useful across many different coating application areas. It has the lowest Tg (glass transition temperature) of the CAB portfolio. It also has the second lowest M(n), which enables its compatibility with other coatings components. It is compatible with numerous cross-linking resins and has a lower solution viscosity. In coatings, Eastman CAB-551-0.01 gives clear films, reduces surface tack and mottling, minimizes cratering, improves flow and thermal reflow, and provides inter-coat adhesion and good UV stability. Its good compatibility with a wide range of curing resin systems and its solubility in a wide variety of solvents and solvent combinations make it useful as an additive in numerous coating compositions. Eastman cellulose esters are based on up to sixty percent cellulose, one of the most abundant natural renewable resources. This product is manufactured, stored, handled and transported by Eastman under conditions adhering to current Good Manufacturing Practices for food contact applications. They meet requirements for use in certain food contact applications under regulations of the U.S. Food and Drug Administration (21 CFR), European Commission (Regulation 10/2011) and the Swiss Ordinance on Materials & Articles in Contact with Food (SR 817.023.21).
