3M 3797 PG Epoxy Adhesive Applicator

The 3M 3797 PG is a clear epoxy adhesive applicator designed for fast bonding tasks. It suits technicians and assemblers who need a short working window and immediate handling strength. The product delivers a smooth stick format that feeds cleanly into compatible dispensing equipment. It is not intended for projects requiring extended open time or repositioning flexibility.

Capacity and Working Time

Each stick measures 1 in diameter by 3 in length and begins to harden after 30 sec of working time. This brief window handles small joints, tacking operations and rapid assembly steps comfortably. Larger bond lines or complex alignments will exceed the available open time before the adhesive sets. The fixed 30 sec limit means the applicator cannot accommodate slow, multi-step positioning.

Melting Range and Viscosity Limits

The adhesive melts between 250 Degrees and 380 Degrees F and maintains a consistent viscosity of 2, 650 cps throughout that range. This narrow viscosity band ensures predictable flow but offers no adjustment for gap-filling or vertical sag control. Electrically insulating properties are absent, so the material cannot serve as a dielectric barrier. FDA compliance under 21 CFR 175.105 covers indirect food contact only.

Questions about this item

Will the 30-second working time bond to surfaces that have old adhesive residue?

The 30-second working time allows quick positioning; clean surfaces thoroughly first to ensure the epoxy adheres properly rather than sticking to old residue.

How can I confirm the 3797 series epoxy is curing at the correct rate after application?

The adhesive begins to harden within 30 seconds at room temperature; a firm, tack-free surface after that window indicates normal curing.

Does the package include the 1-inch diameter by 3-inch length sticks only, or is a dispensing gun also supplied?

The box contains the smooth-stick epoxy cartridges; a compatible hot-melt applicator gun must be purchased separately.
