Applications and Fabrication Techniques • • • • • • • • DERAKANE* 8084 Resin is the resin of choice as a primer resin to prepare a substrate surface (steel or concrete) for application of a corrosion resistant lining. DERAKANE 8084 Resin can be use for RTM, hand-lay, spray-up, filament winding and other industrial FRP applications. For applications requiring even higher elasticity and impact resistance, DERAKANE 8090 Resin can be used. Benefits DERAKANE 8084 Resin has exhibited chemical resistance across a broad range of acids, bases and organic chemicals. Resin of choice as a primer to prepare a substrate surface for application of a corrosion resistant lining. It exhibits outstanding adhesive strength on different types of steel, aluminum and concrete. Superior elongation and toughness provides FRP equipment with better impact resistance and less cracking due to cyclic temperature, pressure fluctuations, and mechanical shocks providing a safety factor against damage during process upsets or during shipping and installation. Has exhibited superior property retention under dynamic fatigue conditions. Approved for use in the manufacture of ships under a DNV (Det Norske Veritas) certificate.

Gel times may vary due to the reactive nature of these products. Always test a small quantity before formulating large quantities. (4) phr = parts per hundred resin (5) Materials: Norac Norox MEKP-925H Methylethylketone peroxide (MEKP) or equivalent low hydrogen peroxide content MEKP, Cobalt Naphthenate-6% (CoNap6%), Dimethylaniline (DMA), and 2,4- Pentanedione (2,4-P). Use of other MEKP or other additives may result in different gel time results. (6) Use of cobalt octoate, especially in combination with 2,4-P, can result in 20 to 30 % slower gel times.

The MSDS should be read and utilized to help users meet their own handling needs and those required by OSHA or other government agencies. The following comments pertain to all DERAKANE and DERAKANE MOMENTUM Resin products and are general guidelines only. Personnel Protection: When using DERAKANE Resins, minimize human contact with resins, initiators, and other modifiers. Appropriate eye and skin/body protection should be worn to avoid contact as detailed in the MSDS. Use sufficient ventilation to control styrene monomer vapors below the applicable government regulated levels. For exposures above the regulated levels, air purifying respirators or self-contained breathing apparatus should be worn. DERAKANE Resins that are completely cured are considered to be toxicologically inert and to present no handling hazards. The finished parts may represent a health hazard from dust inhalation due grinding or machining, especially if they contain glass, silica or metal oxide powders and therefore appropriate respiratory protection should be used. Spills: Trained personnel, properly protected from skin and eye contact and breathing vapors, should perform cleanup tasks. Prior to any cleanup, any possible sources of ignition should be removed. For smaller spills apply sand or other absorbent material onto the resin and shovel the mixture into a container. Larger spills should be contained with a dike and the excess resin collected in containers. Any residue resin should be removed from the floor with hot, soapy water. CAUTION: The use of solvents in the final cleanup can pose unnecessary hazards from breathing vapors and possible ignition. Fires: DERAKANE Resins are classified as flammable materials under NFPA 30, so they must be stored and handled properly to prevent ignition. Fires can be extinguished by conventional means, including foam, dry chemical, and carbon dioxide but water is not normally effective. NFPA Rating: Health=2 ; Flammability=3 ; Reactivity=1 Disposal: Any disposal practice must be in compliance with all federal, state/provincial, and local laws and regulations. State / provincial and local requirements for waste disposal may be more restrictive or different from federal laws and regulations. The preferred waste management option for unused, uncontaminated, unformulated, unaltered DERAKANE Resins is to send them to a licensed or permitted recycler, reclaimer, or incinerator. The same waste management options are recommended for used or contaminated material, although additional evaluation is required. DERAKANE Resins that are fully polymerized are considered to be toxicologically and ecologically inert and should be disposed of properly. Resin Storage: DERAKANE Resins are stable for the shelf-life period stated on the label when stored in original, unopened containers at temperatures between 10-25 °C (50-75 °F) and in a dry place out of direct sunlight. Resins should be used within the shelf life stated on the drum label. Dow cannot honor any claims for credit on resin that has been stored beyond its stated shelf life or outside the recommended storage guidelines.
