3 Hot Melt Adhesive 3764 3748 Technical Data July, 2016 Product Description 3M Hot Melt Adhesives are 100% solids, thermoplastic resins that become fluid when heated and quickly wet the bonding surface. They cool, harden and reach bond strength in seconds, keeping production flowing by eliminating clamps, fixturing and drying, and saving time energy and space. 3M Hot Melt Adhesive 3764 and 3748 bond to a wide variety of substrates such as wood, plain and coated corrugated, fabrics and foams, plastics, and other lightweight materials. 3M Hot Melt Adhesive 3764 Excellent general plastics bonder with low temperature flexibility. 3M Hot Melt Adhesive 3748 Designed especially for low surface energy plastics and coatings such as polyolefins. Good high temperature stability and thermal shock resistance. Features 100% solids, no VOCs Easy to use Adhesive obtains strength in seconds Designed for plastics and polyolefin bonding, including ABS, PVC, polycarbonate, polypropylene and polyethylene Typical Physical Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.

Surface Preparation: Surfaces must be clean, dry and dust free. Wipe with a solvent Directions for such as isopropyl alcohol for plastic substrates to aid in removing oil and dirt.* Use *Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturers precautions and directions for use. are designed for application 2. Application: 3M Hot Melt Adhesives with a 3M Hot Melt Applicators. Read and follow the precautions and directions for use in the users manual before operating the applicator. 3M Hot Melt Adhesives are applied at 350- 385F. Extruded bead sizes can be customized using 3M applicator tips. 3M Hot Melt Adhesive 3764 3748 3. Coverage: 3M Hot Melt Adhesives yield approximately 430 linear feet per pound of Directions for adhesive when extruded as a 1/8 diameter semi-circular Use (continued) 4. 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. Typical Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.
