Product Identity

3M 3747 Hot Melt Adhesive is a tan, 100-percent-solids thermoplastic stick formulated for bonding ceramic, glass, metal, plastic and wood. It suits assembly, repair and fabrication tasks where a quick-setting, electrically non-insulating adhesive is required.

Build Integration

Each stick measures 1 in diameter by 3 in length and fits standard hot-melt applicators that accept this format. The 45-second work life lets you position parts before the adhesive begins to harden at 145 degrees F, freeing you from clamps or extended fixturing.

Sustained Load Behaviour

Under continuous stress the bond delivers a shear strength of 430 psi and maintains a consistent viscosity of 4,100 cps. It complies with FDA 21 CFR 175.105 but is not UV-resistant, so prolonged outdoor exposure or electrical insulation needs are not supported.

What is the melting temperature and does the adhesive produce noticeable fumes during extended use?

It melts at 145 degrees F and the manufacturer notes that the product is not low-odour, so some smell can be expected when it is heated continuously.
