Room Temperature Curing
Magna-Tac M666 is an easy to handle, equal mix by volume, 100% reactive, two part, formulated epoxy adhesive which produces high strength bonds between a wide variety of materials. Coated parts may be mated without delay to cure at room temperature and do not require pressure other then that necessary to keep components in intimate contact during cure.
Fully cured bonds exhibit minimal shrinkage, are electrical insulators and provide excellent resistance to weather, galvanic action and most chemical, acids and alkalis.
It is especially designed for:
NOTE: Fully cured panels consisting of degreased steel or etched aluminum skins and foamed glass cores produced with this adhesive pass PFL Test Cycles (ASTM Test D1037-55T0) also given in ASTM C481, Cycle A).
Fully Cured metal to metal bonds, tested at room temperature using MMM-A-132 procedures, yield up to 3500 psi. Bonds involving expanded styrene foam withstand 175F to 200 hours without cell attack.
All bonding surfaces must be thoroughly cleaned, degreased and dried. For plastic surfaces, remove mold release if any.
Preparation of adhesive
At room temperature, assemblies can be handled in approximately 8-14 hours. MagnaTac M666 develops 85% of its maximum strength in 24-48 hours.
NOTE: The bond continues to advance in strength for approximately one week.
If a faster cure is required, the following cycles may be used:
Bonds will continue to improve in strength at room temperature until optimum is reached, usually within 3-4 days.
Typical lap shear values obtained when Magna-Tac 666 is used to bond 0.064" etched 2024T3 aluminum alloy to itself in a 1/2 overlap are as follows:
