SÄKAFLAKE 900 Black 3K
Plural-component, Novolac Vinyl Ester-based Conductive and Abrasion Resistant Lining / Coating for Highly Acidic to High Alkali Media. Matt, Black Finish.
SÄKAPHEN SÄKAFLAKE 900 Black 3K is a plural-component Novolac Vinyl Ester resin enhanced further by the addition of graphite and glass flakes to provide an electrically conductive (statically dissipative), abrasion resistant lining / coating, offering protection against water vapor diffusion (ΔT 85°C). ). Further, offering chemical resistance against aggressive substances such as acids, salt solvents, flue gases and all types of water including brackish, river, sea water and deionized water.
SÄKAFLAKE 900 Black 3K is specifically formulated and designed to be self-priming for direct to metal application and can be applied on site and on concrete. Upon polymerization the lining is fully machinable and delivers exceptional quality when used for complex structures and fabrications such as Columns where the diameter may be reduced by use of internal baffles or support rings. Bespoke formulation allows for efficient application, even in extreme environmental conditions and has excellent sag resistance allowing for wet on wet application up to 3mm (3000 microns).
SÄKAFLAKE 900 Black 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.
Suitable for the lining or coating of Ancillary Heat Exchanger equipment such as Water Boxes, Channel and Covers, Blowers, Fans, Wash Towers, Process and Storage Tanks, Vessels, Tank Containers, Compressor Casings, assorted Flue Gas Desulfurization equipment including Flue Gas Funnels and Channels. In particular, for equipment requiring water vapor diffusion resistance with high temperature gradients.
