Available in a 5-gallon container for use in bulk equipment only
Designed for use with PUR Adhesive Dispensing Equipment 3M™ Scotch-Weld™ Purge Material should only be dispensed through bulk equipment specifically designed for use with hot melt polyurethane reactive (PUR) adhesives. All equipment must be used in strict accordance with the recommendations of the manufacturer.
Directions for Use 3M™ Scotch-Weld Purge Material 3756 (PDF, 9.87 Kb) is designed to purge material balance of 3M™ Scotch-Weld™ polyurethane reactive adhesive from PUR application equipment prior to extended shutdown periods. 3M™ Scotch-Weld™ Purge Material should be dispensed at 250°F / 121°C. Frequency of use and quantity of this extruder will depend on the type and configuration of the application equipment. 3M™ Scotch-Weld™ Purge Material can also be used for first time start-up (for a "dry" run) of PUR application equipment. Because 3M™ Scotch-Weld™ Purge Material is nonreactive, pre-production modifications to equipment can be performed without the potential for curing in the equipment.
Formulated for extrusion of PUR adhesives from bulk equipment
Understanding 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Adhesives 3M™ Scotch-Weld ™ PUR Adhesives are one-component, moisture-curing urethane adhesives that are applied warm to create dramatically strong bonds to a variety of substrates such as wood, fiber reinforced plastic (FRP) and many other plastics to themselves, to metal and to glass. Fast-acting strength begins to build as the adhesives cool for rapid, convenient application with minimal downtime from clamping or fixturing. These adhesives can be extruded from hand held or bench mounted 3M™ 3M™ Scotch-Weld™ PUR Easy 250 Applicator.
PURs offer attractive options: from woodworkers searching for thin bond lines and replacing unsightly mechanical fasteners, to plastic, glass and metal materials assembly in automotive, electronics, general assembly and many other industries.
