2 Storage UNIPLEX 280CG should be kept in its tightly sealed original container in a dry place. If stored properly, the product is at least stable for one year. The product has the tendency to agglomerate. This does not affect the product quality. Soluble in all common solvents; the solubility in cold water is low. Packaging Drums Solubility General properties UNIPLEX 280 CG is a stable, clear, odourless, and non-crystalline brittle solid with a reasonably sharp softening range starting at around 93 C. It has excellent ultraviolet light stability. UNIPLEX 280CG is compatible with a broad range of resins, plasticizers, and solvents, and insoluble in water and aliphatic hydrocarbons. The UNIPLEX 280CG is specifically designed for the coating and ink industry. However, this product may also be used in numerous applications areas as indicated by the listing of compatibilities attached. In addition to usage in the formulation of clear coatings for wood, paper and metal, and in formulation of ink systems, the properties of Sucrose Benzoate indicate that it should be of interest in metallic and pigmented coatings, and heat seal coatings. UNIPLEX 280CG may be used to particular advantage in UV coating and inks. UNIPLEX 280CG improves the UV systems stability and allows easier processing. In addition, it imparts good film hardness, excellent gloss, and depth of gloss. UNIPLEX 280CG is an outstanding modifier for clear lacquers. It provides exceptional clarity with high gloss, excellent resistance to ultraviolet light, high film hardness combined with good flexibility, and excellent resistance to water and alcohol.

6 Stability 1. Ultraviolet Light Supported films of Sucrose Benzoate were prepared from toluene solution. Exposure was made using an Atlas Fade-O-Meter at approximately 60 C.Exposure time: 3000 hours. Appearance: No color change or evidence of degradation. 2. Hydrolytic Sucrose Benzoate was held in contact at 100 C with solutions shown below. Change in acidity of aqueous layer was used to determine degree of hydrolysis. Table 8: Hydrolysis Solution Hydrolyzed in 24 hours Hydrolyzed in 96 hours Water Nil Nil 5% solution HCl Nil 0.6% 5% solution Na CO % 2.3% 3. Heat Prolonged heating of Sucrose Benzoate at elevated temperatures causes darkening and increases in acidity. For example, heating for 4 hours in oven at 175 C in aluminium dishes causes gradual colour development from 60 APHA to about 3 Gardner - and 8 hours heating results in Gardner range of This 8 hour heating also causes an increase in acid number from around 0.05 to around 0.35 mg KOH/g. Temperatures below 150 C cause the Sucrose Benzoate to reach a 4 Gardner colour in less than 2 hours. Addition of small amounts of oxirane oxygen containing compounds including epoxy soybean oil, epoxy esters, liquid epoxy resins, and glycidyl phenyl ether imparts improved heat stability to Sucrose Benzoate.
