Säkaline KTW

Solvent Free Two-Pack Epoxy-based Lining for use in contact with Potable Water approved. Satin, Black Finish.

SÄKAPHEN SÄKALINE KTW is a two-pack high-quality hydrophobic epoxy based lining, resistant to varying media ranging from weakly acidic to alkaline as well as all types of water including brackish, river, sea water and deionized water with nanoparticle filling. SÄKALINE KTW is formulated and developed to be self-priming for direct to metal application.

SÄKALINE KTW holds German Potable Water Approval for contact with drinking water (KTW Zulassung) for both Cold Water and Warm Water (60°C). The KTW symbolizes plastics in contact with potable water. Further the lining is certified as per DVGW W270 (hygienic harmlessness concerning migration of chemical substances and the growth of microorganism).

SÄKALINE KTW is solvent free and upon polymerization is fully machinable. The lining can be applied on site.

 

Suitable for the lining of Potable Water Tanks, Pipework, Industrial Water Tanks, Sewage Gas Containers in the paper and pulp industry and Boilers and other Hot Water Tanks. Can be applied on site.
