MHEC Powder : M70
BERMOCOLL M 70 is a non – ionic, water soluble cellulose ether intended as a water retaining and consistency improving additive to cement based mortars. BERMOCOLL M 70 contains methyl, ethyl and hydroxyethyl substitution giving a unique balance between workability and strength.
BERMOCOLL M 70 is used in cement – based tile fix, adhesives and plasters for improvement of workability, consistency, water retention and adhesion.
Normal dosage in mortars is 0.2 – 0.4 % calculated on the dry mortar weight.
BERMOCOLL M 70 is inten ded for dry mixing with other powder materials and should not be used for direct dissolving in water
Safety instructions, Packaging and Storage
Like many industrial processed materials powdery materials, cellulose ether dusts are combustible and can ca use dust explosions. Dust formation must be avoided or kept to a minimum. Care should be taken to prevent ignition from heat, spark,open flames or hot surface.
BERMOCOLL M 70 is packed in a polyethylene bag. Net weight 15 kg. We recommend emptying the bag s from the bottom. The empty bags can be recycled or burned. In unopened bags, BERMOCOLL M 70 can be stored for several years. In opened bags, the moisture content of BERMOCOLL M 70 will be influenced by the air humidity.
At the temperatures above 250°C ( 480°F), charring of BERMOCOLL M 70 will occur. At high temperatures and in contact with an open flame, BERMOCOLL M 70 will burn slowly with the characteristics of cellulose.
