3M Polygun AE and AE LT hot melt glue guns

3M Polygun AE and AE LT Overview

The Scotch-Weld AE II is the perfect gun for light industrial work and is definitely a step above the average craft grade glue gun. This gun is the only one in the 3M glue gun range that uses a very standard glue stick size, 1/2" X 12", allowing you to use competitors' glue sticks in this gun.

The Scotch Weld AE II comes in both standard and low temp versions but cannot be changed. The standard temp is better for every day jobs where the low temp version, the AE II LT, will work better with sensitive substrates like foam or fabric. You can tell the difference between standard and low temp guns by the color, orange being standard temp and blue representing the lower temp LT version.

Be sure to use low temperature hot melt with the LT version and standard temperature hot melt with the standard AE II gun.

3M Polygun LT low temp glue gun

3M Polygun LT Overview

The 3M Polygun LT is a step up from the AE II glue gun and has caused a little confusion for customers in the past due to it's unusal stick size.

This low temp gun uses the 3M TC LT glue sticks, which are 5/8" X 2" and meant for low temperature dispensing. The most popular glue stick for this gun is the 3M 3798LM Gummy Glue.

One feature that we aren't totally thrilled about its the fact that sticks are fed through by manually pushing the stick through the gun with your thumb. It isn't difficult but we still prefer a trigger system.
