The low molecular weight liquor polyamide resin is a good flexibilizer and curing agent of epoxy resin. For its excellent behavior, it can be used in epoxy coating, epoxy adhesive, epoxy casting seal and epoxy varnish. It can be widely used. First. Performance characteristic l Low toxicity, flexibility, corrosion inhibiting, fire-resistant. l Easy to proportion with epoxy. l During the produce, some kinds of soluble assistant such as flexibilizer, reinforcer, thinner, accelerant, coupler and so on can be added into the resin. l Some kinds of filler can also be added such as cement fine grit, quartz sand, silicon fine powder, aluminum cream, calcite powder and some light filler like calcium carbonate and aerosil. Second. Performance index and basic formula Type Performance index Basic formula Amine value mgKOH/g Viscosity mPa.s/40℃ Color Fe-Co 100 epoxy (E-44、51) 650 22020 10000~60000 ≤8 50~100 651 40020 1000~6000 ≤8 30~70 Note: With the increase in the amount of weight of curing agent, flexibility increases, fire-resistant decreases, curing speed accelerates, anti-impact ability enhances and adhesion improves. With the decrease of the curing agent, fire-resistant increases, anti-corrosion ability improves and fragility increases. Third. Packaging, Reserve and Transportation There are 15Kg and 180 Kg two kinds of package with one barrel. It must be kept in dry and cool place. The storage life is about one year.
