If you have a liquid or vapor chemical hazard, try searching the Chemical Resistance Database. This database will show you permeation data for all of the fabrics tested against a given hazard. Once you are able to determine a suitable fabric, you will have the flexibility of selecting a suitable garment design and seam construction yourself. With regard to chemical resistance, a good quality Bis-A epoxy can resist 70% sulfuric acid but a Bis-F Novolac epoxy can comfortably survive 98% sulfuric acid. Hardener (“Part B”) Chemistry: The addition of a hardener to the “Part A” resin initiates a chemical reaction in which the epoxide groups in epoxy resin react with the curing ...
HAND PROTECTION: Wear chemical-resistant gloves such as: Nitrile, neoprene, butyl. SKIN AND BODY PROTECTION: Wear long sleeve shirts/long pants and other clothing as required to minimize contact. RESPIRATORY PROTECTION: Do not breath e gas/fumes/vapour/ or spray. Epoxy adhesives are better in heat and chemical resistance than other common adhesives. In general, epoxy adhesives cured with heat will be more heat- and chemical-resistant than those cured at room temperature. The strength of epoxy adhesives is degraded at temperatures above 350 °F (177 °C).ECO - Epichlorohydrin Rubber. Epichlorohydrin rubber (ECO) has properties similar to nitrile rubber but with better heat, oil and petrol resistance. Has low gas permeability and better low temperature flexibility than NBR. Its resistance to acids, alkalis and ozone is excellent.CHEMICAL COMPATIBILITY 5-5 Form No. 314-790 Rev. AA Chemical Compatibility Guide Trade Name Reference Trade Names, their manufacturers and abbreviations for plastics elastomers and thermoplastic elastomers are shown in Table 1. This list should not be considered to be complete; the intent is only to show representative materials for each of the ...
There are differences between types of Viton in terms of chemical resistance and mechanical properties. Whether your application is automotive, chemical processing or any number of other industrial applications, there is a particular type of Viton that best meets your specific performance requirements.Atlantic Gasket Corporation stocks both sponge and foam materials, which exhibit different mechanical and physical properties. Each is available in several densities, and polymer variations that make them suitable for diverse applications from gaskets, seals, spacers and cabinet bumpers to adhesive backed tapes just to mention a few of the most common uses.Epoxy resins have displayed widespread effectiveness in various applications such as composites, adhesives, paints and coatings, construction material and others, owing to their chemical and physical properties such as excellent chemical resistance, low curing time, high flexibility and strength.
Epichlorohydrin combines low gas and solvent permeability with high resistance to hydrocarbon oils and fuels. Epichlorohydrin is very resistant to weathering and ozone due to complete saturation within the polymer chain. Epichlorohydrin also remains stable during low to high temperature cycling.
