Technical Data Sheet

Issued May 2016

Duresta™ 10GP Glycidyl Ester

 

 

Description

Duresta 10GP acid scavenger is the glycidyl ester of a highly branched monocarboxylic acid with an excellent reactivity towards carboxylic acids:

 Chemical reaction - esterification Duresta  

 

Applications

Duresta 10GP glycidyl ester is used as an acid scavenger to reduce the acid value of esters, polyesters resins and polymers. It is usually dosed to these products at the end of their chemical synthesis when they are still at elevated temperature. The unique reaction characteristics and properties make Duresta 10GP glycidyl ester attractive for a wide variety of applications, particularly those requiring very low acid values such as synthetic lubricants, high performance polyesters and specialty ester based polymers. Typically, the derived products have an improved hydrolytic stability due to their extremely low acid value.

 

Usually, 4.3 to 30 mg/g Duresta 10GP glycidyl ester is used per mg/g KOH of acid value reduction desired. Excess product may be removed by vacuum distillation1

Transportation and Storage

Information on transport, storage, labeling, suitable materials for tank construction, etc, is available from Hexion, via local representative or distributor.

Duresta 10GP glycidyl ester should be stored at ambient temperature (min 5 °C - max 50 °C) in conditions such that moisture is excluded, in the original containers kept tightly closed. Under these conditions, the shelf life should be three years starting from the manufactured date.

1)  In case free Duresta 10GP glycidyl ester level is >1%, the product should be labeled in line with GHS guidelines and in case free Duresta 10GP glycidyl ester  level > 0.1% it should be mentioned in the SDS.

 

 

Handling Precautions

For more detailed information on all aspects relating to Health, Safety and Handling, reference should be made to the Safety Data Sheet of Duresta 10GP glycidyl ester, which is available from your local Hexion representative or distributor. The precautions advised therein should be strictly observed.
