Fortec #4020 Toughened Hi Modulus Epoxy Gel


pdf PRODUCT SPECIFICATIONS: MSDS (Part A) | MSDS (Part B) | Data Sheet


The gel and cure times are affected by ambient temperature and epoxy mass,or glue line thickness. Curing data is based on 72oF (22oC) ambient temperature. Warmer temperatures and a larger mass will increase cure speed,reducing cure time. Cure time is reduced by approximately one half with every 18oF (10oC) increase in temperature. A smaller mass or cooler temperature will reduce the cure speed, increasing cure time. Always dispense adhesive at or above 70oF to assure the proper mix ratio
