3M 3762 LM Hot Melt Glue (Low Temperature)

Q: What does "LM" stand for in 3M 3762LM?

A: "LM" stands for Low Melt. It indicates that the glue is formulated to melt and dispense at a lower temperature ($250^\circ\text{F}$) compared to standard hot melt adhesives ($350^\circ\text{F} - 385^\circ\text{F}$).

Q: Can I use 3M 3762LM in a standard high-temperature glue gun?

A: No. 3762LM must be used with a low-temperature 3M applicator (such as the 3M Hot Melt Applicator LT or Polygun LT series). Standard high-temp applicators will overheat the adhesive, causing runny viscosity, degradation, or charring.

Q: What stick formats and sizes are available for 3762LM?

A: 3M 3762LM is produced in several stick drive formats, including Q ($5/8\text{ in} \times 8\text{ in}$ ridged), TC ($5/8\text{ in} \times 2\text{ in}$ smooth), PG ($1\text{ in} \times 3\text{ in}$ slotted), and AE ($1/2\text{ in} \times 12\text{ in}$).

Q: How much coverage does one pound of 3762LM glue sticks provide?

A: One pound yields approximately 430 linear feet when extruded as a continuous $1/8\text{-inch}$ semi-circular bead.

Q: Is 3M 3762LM safe for food packaging?

A: Yes, it complies with FDA regulation 21 CFR 175.105 for indirect food contact, making it suitable for outer food packaging and shipping cartons.
