SÄKAFLAKE 900 Topcoat 3K

Plural-component, Novolac Vinyl Ester-based Lining / Coating for Highly Acidic to High Alkali Media. Satin, Green Finish.

SÄKAPHEN SÄKAFLAKE 900 Topcoat 3K is a plural-component Novolac Vinyl Ester resin enhanced with micro glass flakes to provide an abrasion resistant lining / coating. SÄKAFLAKE 900 Topcoat 3K offers chemical resistance against aggressive substances such as acids, bases, salt solutions and all types of water, including brackish, river and sea water as well as deionized water.

Once developed as smooth surface topcoat for the SÄKAFLAKE range of products, SÄKAFLAKE 900 Topcoat 3K nowadays is a standalone product offering the superior chemical resistance of a Novolac Vinyl Ester based product with the reinforcement of microfine glass flakes at a lower dry film thickness.

SÄKAFLAKE 900 Topcoat 3K is specifically formulated and designed to be self-priming for direct to metal application. Upon polymerization the lining is fully machinable. The lining can be applied on concrete as well. SÄKAFLAKE 900 Topcoat 3K is an ultra-high solid / low solvent product with a volume of solid (wt%) of plus 95%. The lining is resistant to temperature fluctuations.

 

For the purpose of lining / coating sealing faces of items which have been lined or coated with SÄKAFLAKE 900 or SÄKAFLAKE 957 or alternatively lining or coating items such as Process Vessels, Pipelines and various other equipment susceptible to chemical exposure where a Novolac Vinyl Ester system is required. Can be applied on site.
