Novolac type epoxy vinyl ester resin product description
TC-907 is Novolac epoxy vinyl ester resin. It combines excellent mechanical properties at high temperatures, such as tensile strength, bending strength, excellent chemical mixtures, oxidizing chemicals and solvents for corrosion. TC-907 is widely used for its excellent toughness and fatigue resistance due to its special properties at high temperatures.
Applications
w Chemical storage tanks, pipes, flue gas desulfurization systems (FGD), scrubbers, ducts.
w Corrosion resistant flooring while incorporated with aggregates.
w Equipment specified to handle mixture of air, exhaust gases or potentially flammable liquids.
Fabrication Methods
w Can be easily applied by hand lay-up laminating, spray-up, pultrusion, resin transfer molding (RTM) and filament winding.
w Can be used in polymer concrete casting.
w Can comply with US FDA regulation 21 CFR 177.2420 if the resin is properly formulated and cured.

NOTICE IN USE
1. If TC-907 is blended with cobalt-salt promoters, shelf life will be shortened. Promoted TC-907 must be used within two weeks.
2. The gel time of TC-907 is affected primarily by catalyst concentration and temperature. The variations of cure characteristics may be caused by the variations of catalyst, humidity, pigment, fillers and other additives. It is recommended that the fabricators check the cure characteristics with a small quantity resin before proceeding for bulk production.
3. TC-907 contains organic solvent (styrene). Keep away from heat, sparks and flames.
4. TC-907 is a potentially reactive chemical. Please store it in dark and keep away from heat and direct sunshine.
5. Containers, not completely emptied must be closed immediately after use.
PACKAGE
Standard packing is 200 kg steel drum.
