  • Product typeSealing Compound
  • 30-second working time speeds assembly tasks
  • 5/8 inch diameter by 2 inch stick fits standard applicators
  • Melting range 250 to 380 degrees Fahrenheit for reliable bonding
  • Minimum and maximum viscosity 2,650 cps ensures consistent flow
  • FDA 21 CFR 175.105 compliant for indirect food contact

Purpose and User

3M 3797 TC hot melt adhesive is supplied as smooth off‑white sticks measuring 5/8 in diameter by 2 in length. The formulation suits assembly, packaging and general bonding tasks where a fast‑setting, electrically non‑insulating compound is required. It complies with FDA 21 CFR 175.105 for indirect food contact.

Application Window

The adhesive melts between 250 and 380 °F and provides a working time of about 30 seconds before it begins to set. Viscosity is consistent at 2,650 cps, giving predictable flow through standard hot‑melt applicators during normal use.

Sustained Operation

Under continuous dispensing the melt range and fixed viscosity maintain steady bead control without sudden thickening. The 30‑second open time remains the practical limit for repositioning, so extended runs require a workflow that matches that cycle.

Questions about this item

How do I install the 5/8 in diameter stick and what step is often missed?

Insert the stick into a hot-melt gun pre-heated to 250 to 380 degrees F; the step often missed is waiting for the gun to reach temperature before feeding the stick so the adhesive flows at the rated 2 650 cps viscosity.

What maintenance or replacement will the 3797 TC sticks need later?

The sticks are single-use consumables; once a 2 in stick is melted and the 30 second working time expires, it cannot be re-used and must be replaced with a new stick.

What limit appears first during sustained bonding with the 30 second working time?

The 30 second working time is the first limit; after that the adhesive begins to set and bond strength drops, so each joint must be assembled and positioned within that window.
