Bitochem - M

Chemical Resisting Bitumen Mastic

Bitochem - M is acid alkali resisting mastic for use as a protective  impervious  layer  for concrete , brick  work  steel  etc . Bitochem - M  mastic  have  good  resistance  to  large number of mildly  corrosive  conditions . The  floor  system in  most factories comprises a structural   load  carrying  floor , usually  with  a  screed  and with a wearing finish. The structural floor and screed  together with , for convenience be called a sub - floor and are assumed to be  constructed from  normal or  rapid hardening Portland  cement ,  and  therefore  concrete  made  from  it are attacked by acids and chemicals.

The risk of corrosion of steel reinforcement must also be considered . If acids , salts, or chemical can reach the steel it will  inevitably  corroded . It  should  be  particularly  noted  that  solution  or common salt , which  do  not  attack  concrete , may  reach  steel   reinforcement   and   produce corrosion , and as such liquid-tight protection is therefore required.

Bitochem-M mastic is an invaluable material for use as a preventive coating concrete , brick work  wood , iron , etc. where  corrosion  has  to  be  considered . Its  adhesion  to concrete surface is excellent . It is applied over rough concrete surface previously  primed  with  Bitochem - P primer. For wear and tear as a floor cover, we recommend 15 to 20mm thick layer of  Bitochem , mastic compound and for general cover work such as for walls or vertical surface we  recommend 12 to 15mm thick layer.

Concrete surface must be cleaned and rough. No primer should be applied over smooth, polished and wet surface. After  cleaning  the  concrete surface one coat of Bitochem - P primer  shall  be applied  with  brush  and  allowed  to  dry  thoroughly .  The  drying  time  will  depend   upon  the temperature .

Bitochem - M  mastic  shall be broken  into  small  pieces and put into heating vessel then heated . The surface on which  it  is  to  be  applied  should  be  primed  with  Bitochem - P  primer . It is applied with trowel or straight edged piece of wood . The surface shall be put under service after 24 hours of application of mastic . Bitochem - M mastic is not suitable where , there is excessive heat or solvent , mineral oils and greases are anticipated .

Bitochem - M primer contains volatile and  slightly toxic solvent , keep away from spark and open flames at working area
