UNIPLEX 280 CG

SUCROSE BENZOATE

CAS NO.  12738-64-6

 

UNIPLEX 280 CG is a stable, clear, odorless, and non-crystalline brittle solid with a reasonably sharp softening range starting at around 200°F.  It has excellent ultraviolet light stability.  Uniplex 280 is compatible with a broad range of resins, plasticizers, and solvents, and insoluble in water and aliphatic hydrocarbons.

 

The UNIPLEX 280 CG is specifically designed for the coating and ink industry.  However, this remarkably clean, clear product may also be used in numerous applications areas as indicated by the listing of compatibilities attached.

 

UNIPLEX 280 CG 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.

 

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 280 CG may be used to particular advantage in UV coating and inks.  The Uniplex 280 CG improves the UV systems stability and allows easier processing.  In addition, it imparts good film hardness, excellent gloss, and depth of gloss.

The following table shows film compatibility of Uniplex 280 CG with various polymers commonly used in processing, formulating, and compounding operations.

 

Sucrose Benzoate and each of the various materials under test were dissolved in a suitable solvent system to permit spreading a wet film 3 or 4 mils thick on a glass plate. After drying and aging at least 48 hours, compatibility was estimated by visual inspection. In certain cases, the Sward film hardness was measured. The abbreviations used in these tables to describe film compatibility are:

 

C	Compatible	Film had glass-like clarity.
CH	Compatible	Film had some haze.
I	Incompatible	Film was translucent or opaque.

 

NOTE: When Sward hardness of film was determined, it is indicated in parentheses following compatibility abbreviation.

 

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 140°F.Exposure time: 3000 hours. Appearance: No color change or evidence of degradation.

 

2. Hydrolytic

Sucrose Benzoate was held in contact with solutions shown below at 100°C. Change in acidity of aqueous layer was used to determine degree of hydrolysis.

 

Solution	Hydrolyzed in 24 hours	Hydrolyzed in 96 hours
Water	Nil	Nil
5% solution HCl	Nil	0.6%
5% solution Na2CO3	1.9%	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 (347°F) in aluminum dishes causes gradual color development from 60 APHA to about 3 Gardner - and 8 hours heating results in Gardner range of 5-10. This 8 hour heating also causes an increase in acid number from around 0.05 to around 0.35 mg. KOH/gram.  Temperatures below 150°C (302°F) cause the Sucrose Benzoate to reach a 4 Gardner color 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.

 

TOXICITY

 

Sucrose Benzoate LD₅₀ orally in rats is greater than 5g. / kg. All rats tested (12) survived forced-feeding 50% suspension in olive oil at level of 5 grams Sucrose Benzoate per kilogram body weight. This was the maximum amount which could be administered using this technique.

Sucrose Benzoate is not a primary skin irritant, nor an eye irritant, based on tests with rabbits using terms and procedures outlined in the Federal Hazardous Substance Labeling Act.

Until further data are obtained, it is recommended that Sucrose Benzoate be handled with the usual precautions for organic chemicals.
