Bermocoll E 230 X cellulose ether

Bermocoll

BERMOCOLL E 230 X is a non-ionic, water soluble cellulose ether. It improves the consistency, the stability, and the water retention of water based products.

 

Specifications

BERMOCOLL E 230 X is low viscosity grade of ethyl hydroxyethyl cellulose.

Applications

BERMOCOLL E 230 X is used for thickening and stabilizing effects in mortars and other building glues.

BERMOCOLL E 230 X is also used as a dispersing, binding and stabilizing agent for powder

materials dispersed in water.

The simultaneous viscosity increase is moderate. Normal dosage is 0.4 - 0.8 % calculated on the dry mortar weight.

BERMOCOLL E 230 X is also used in gypsum based crack fillers. For this application, a suitable concentration is about 1 %.

BERMOCOLL E 230 X is intended for dry mixing with other powder materials and should not be used for direct dissolving in water.

 

Packaging and Storage

BERMOCOLL E 230 X is packed in multiply paper bags with an inner polyethylene bag. Net weight 20 kg (approx. 44 lbs). We recommend emptying the bags from the bottom. The empty bags can be recycled or burned. In unopened bags, BERMOCOLL E 230 X can be stored for several years. In opened bags, the moisture content of BERMOCOLL E 230 X will be influenced by the air humidity.

 

At the temperatures above 250°C (480°F), charring of BERMOCOLL E 230 X will occur. At high temperatures and in contact with an open flame, BERMOCOLL E 230 X will burn slowly with the characteristics of cellulose.
