1. Surface Preparation: Surfaces must be clean, dry and dust free. Wipe with a solvent such as isopropyl alcohol forplastic, metal and glass substrates to remove oil and dirt.**Note: When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’sprecautions and directions for use.
2. Application: 3M™ Hot Melt Adhesives are designed for application with a 3M™ Hot Melt Applicators. Read and follow
the precautions and directions for use in the user’s manual before operating the applicator. 3M™ Hot Melt Adhesives areapplied at 350-385°F. Adhesives yield approximately 430 linear feet per pound of adhesive when extruded as a 1/8”
diameter semi-circular bead. Extruded bead sizes can be customized using 3M™ applicator tips.
3. Coverage: 3M™ Hot Melt Adhesives yield approximately 430 linear feet per pound of adhesive when extruded as a1/8” diameter semi-circular bead.
4. Set up time: After the bond is made, 3M™ Hot Melt Adhesives immediately build strength and no clamping isnecessary. Set will occur faster on cold or metallic substrates.

Storage and Shelf LifeStore under normal conditions of 16° to 27°C (60° to 80°F) and 40 to 60% relative humidity in the original packaging,out of direct sunlight. For best performance, use this product within 24 months from date of manufacture.
