Highly abrasion and impact resistant. For use on pipes, tank linings, hopper cars, concrete and surfaces that need chemical resistance. High hydrocarbon resistance. Also available as BIO-CHEM 330HHA for application onto hot surfaces up to 220°F.
HIGH PERFORMANCE, 100% SOLIDS EPOXY COATING FOR AGGRESSIVE CHEMICAL EXPOSURES
BIO-CHEM™ 330 is a Novolac® resin based coating designed for applications where resistance to aggressive chemical exposure is of paramount importance. The sophisticated resin formula has excellent resistance to acids, acid fumes and a wide variety of solvents.
BIO-CHEM™ 330 cures to a very tough, abrasion and impact resistant film. Use as a hopper car lining exposed to impact, abrasion and chemical fumes is particularly recommended.
The high heat resistance of BIO-CHEM™ 330 makes it very attractive for down-hole applications exposed to high ambient temperatures and hydrocarbons.
Application is by heated plural 1/1 airless spray with easy touch up by brush or roller.
DOWN-HOLE TUBULAR COATING:
ID and OD coating, especially suitable for “Ruffcoat” OD treatment.
High hydrocarbon chemical resistance and early return to service make BIO-CHEM™ 330 an ideal high build tank lining.
HOPPER CAR LINING:
Excellent physical and chemical resistance properties.
Excellent adhesion to concrete and chemical resistance

Surface must be free of oil, grease, dirt etc. For steel in atmospheric service an SSPC-SP-6 Commercial blast is the minimum acceptable standard of surface preparation.
For steel in immersion service an SSPC-SP-5 “white metal” blast standard is required. An angular surface profile of 2 – 3 mils, (50 – 75 microns), is recommended. Substrate temperature should be 40’F or above with RH below 85%.
Concrete is best prepared by brush blasting at a reduced pressure in order to yield a “medium sandpaper” texture free of gross surface deposits or contamination.
BIO-CHEM™ 330 is supplied in 10 gallon kits of two 5-gallon containers of epoxy base and curing agent respectively. When applied premixed the components must be intimately mixed before application taking special care to incorporate components from the walls and base of the mixing vessels, Note: unmixed components will never cure.

CURING BEFORE SERVICE:
Allow 72 hours curing at 77’F before immersion service in hydrocarbon service – check with TFT before scheduling return to service.
