Eastman Solus™ 2300 performance additive is a dry, free-flowing powder that is convenient to handle. It is soluble in a wide range of solvents and compatible in most high solids coatings systems. When Solus 2300 is dissolved in appropriate solvents a clear, colorless solution is produced.Eastman Solus 2300 performance additive is based on cellulose, one of the most abundant natural renewable resources, from trees harvested from sustainably managed forests. The calculated approximate bio-content value of 43% for Solus 2300 was determined by using six bio-based carbon atoms per anhyroglucose unit divided by the total number of carbons per anhyroglucose unit. Although the value reported is not specifically measured for bio-carbon, it can be estimated based on typical partition data.
