AEROPOXY Laminating Materials
PR2032 is a medium viscosity, unfilled, light amber laminating resin that is designed for structural production applications. When used with the five hardeners listed here, the combinations provide excellent wet-out of fiberglass, carbon and aramid fibers. Special additives have been incorporated into these products to promote chemical adhesion to fabrics made with these fibers. Typical applications include aircraft and sailplane skins and structural components, auto bodies, radomes and prototype parts.
Hardeners PH3660, PH3663 and PH3665 are the standard production hardeners for fabricating composite parts. PH3660 has a one hour working time, PH3663 a 90 minute working time, and PH3665, with two hours working time provides more time for construction. The 4 hour working time of PH3670 provides sufficient time for very large and/or more complicated laminates when needed. PH3630 is a faster setting hardener that can be used for patching and repairs, and smaller laminates. All five of these hardeners provide similar mixed viscosities, so handling will be basically the same, except for the different working times.
These products can be considered low toxicity materials that have minimum hazard potential when used properly and in a clean and responsible manner. PR2032 does not contain any hazardous diluents or extenders. Hardeners PH3630, PH3663, PH3660, PH3665 and PH3670 do not contain methylene dianiline ( MDA), or other potentially harmful aniline derivatives. Neither the resin nor the hardeners will crystallize in normal shipping and storage conditions, including refrigerated storage. All components have excellent moisture resistance, for minimal problems in high humidity environments.
