AEROPOXY PH3663 HARDENER

Description

Hardener PH3663 is the standard production hardener for fabricating composite parts. PH3663 has a 90 minute working time which provides more time for construction. This hardener provides similar mixed viscosities, so handling will be basically the same, except for the different working times.

This product can be considered low toxicity material that has minimum hazard potential when used properly and in a clean and responsible manner. Hardener PH3663 does 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.
