EPOXY VINYL ESTER RESIN
Product Description
SWANCOR 905-N is a high performance brominated epoxy vinyl ester resin. The advantages combines excellent corrosion resistance, good mechanical strength and flame retardancy. SWANCOR 905-N presents excellent performance at elevated temperature and meanwhile excellent flame retardancy. It is designed to provide superior toughness with excellent fatigue resistance due to high heat distortion temperature.
Applications
• Chemical storage tanks, pipes, flue gas desulfurization systems (FGD), scrubbers, ducts and grating.
• Corrosion resistant flooring while incorporated with aggregates.
• Equipment specified to handle mixture of air, exhaust gases or potentially flammable liquids.
• Military applications such as Kevlar fiber based panels.
Fabrication Methods
• Can be easily applied by hand lay-up laminating, spray-up, pultrusion, resin transfer molding (RTM) and filament winding.
• Can be used in polymer concrete casting.
• Can comply with US FDA regulation CFR 177.2420 if the resin is properly formulated and cured.

Notice in use
1. If SWANCOR 905-N is blended with cobalt-salt promoters, shelf life will be shortened. Promoted SWANCOR 905-N must be used within one week.
2. The gel time of SWANCOR 905-N 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. SWANCOR 905-N contains organic solvent (styrene). Keep away from heat, sparks and flames.
4. SWANCOR 905-N 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.
MATERIAL SAFETY AND HANDLING INFORMATION
SKIN CONTACT:
Thoroughly wash exposed area with soap and water immediately. Remove contaminated clothing. Launder contaminated clothing before re-use.
EYE CONTACT:
Flush with large amount of water immediately and continuously for 20 minutes, lifting upper and lower lids occasionally. Get medical attention.
INGESTION:
Do not induce vomiting. Keep person warm, quiet and get medical attention. Aspiration of material into the lungs can cause chemical pneumonitis which can be fatal.
INHALATION:
If affected, remove individual to fresh air. If breathing is difficult, administer oxygen. If breathing has stopped, give artificial respiration. Keep person warm, quiet, and get medical attention.
PERSONAL PROTECTION:
Do not breathe vapors. High concentration of vapor can be hazardous. Keep out of sewers. Eliminate all sources of ignition in vicinity of spill or released vapor to avoid fire or explosion. For large spills, warn public of downwind explosion hazard. Check area with explosion meter before re-entering area. Ground and bond all containers and handling equipment.
RESIN STORAGE
Keep away from ignition sources; flames, pilot lights, electrical sparks, and sparking tools. NO SMOKING. Do not store in direct sunlight. Store separate from oxidizing materials, peroxides, and metal salts. Keep container closed when not in use. To ensure maximum stability and maintain optimum resin properties, resins should be stored in closed containers at temperatures below 25oC (77oF). Copper or copper containing alloys should be avoided as containers.
SPILLS
Eliminate all ignition sources (flares, flames, including pilot lights electrical sparks). Persons not wearing protective equipment should be exclude from area of spill until clean-up has been completed. Stop spill at source, dike area of spill to prevent spreading, pump liquid to salvage tank. Remaining liquid may be taken up on sand, clay, earth, floor absorbent or other absorbent material and shoveled into containers.
WASTE DISPOSAL
Destroy by liquid incineration in accordance with applicable regulation. Contaminated absorbent should be disposed in accordance to government regulations.
PACKAGE
Standard packing is 200 kg steel drum.
