3 Hot Melt Adhesive 3750LM 3750 Technical Data July, 2016 Product Description 3M Hot Melt Adhesives are heat applied, 100% solids adhesives. They are fast setting thermoplastic adhesives with good hot tack and low to medium viscosity. 3M Hot Melt Adhesives bond to a wide variety of substrates such as corrugated, beadboard, repacking chipboard, recouperage, wood and many other lightweight materials. 3M Hot Melt 3750 Tan Low viscosity adhesive for high flow rate and increased production rate. Ideal for high volume packaging. Use with AE II applicator only. 3M Hot Melt 3750 Clear General purpose adhesive with high peel strength. Use with AE II applicator only 3M Hot Melt 3750LM Low temperature application version with a fast set time. Use with AEII LT applicator only. Features 100% solids, no VOCs Easy to use Fast-setting adhesive obtains strength in seconds Low Melt (LM) adhesives are designed for low temperature application and heat sensitive substrates Quick grab for instant adhesion that cools to a tack free solid Ideal for packaging and many woodworking applications.

Application: 3M Hot Melt Adhesives are designed for use with 3M Hot Melt Applicators (excluding bulk sizes). 3M Hot Melts are applied at 350-385F, Use except the LM series which are designed to be applied at 250-275F. Read and follow the precautions and directions for use in the Applicators Users Manual before operating the applicator. Open Time is the maximum amount of time between dispensing adhesive and joining surfaces. Reported open time are based on 1/8 extruded beads and will vary based on bead size, dispense temperature and ambient temperature. Extruded bead sizes can be customized using 3M applicator tips. 3M Hot Melt Adhesive 3750LM 3750 Directions for 2. Coverage: 3M Hot Melt Adhesives yield approximately 430 linear feet per pound of Use (continued) adhesive when extruded as a 1/8 diameter semi-circular bead. 3. Set Time: After the bond is made, 3M Hot Melt Adhesives immediately build strength and no clamping is necessary. Set will occur faster on cold or metallic substrates.
