3M™ Hot Melt Adhesive 3738

3M™ Hot Melt Adhesive 3738 is a tan-colored, general-purpose thermoplastic adhesive that delivers high delivery rates and a long bonding range for versatile industrial applications. This adhesive provides fast, durable bonds to foundry sand cores, wood, corrugated materials, selected plastics, and chipboard. Dispensing at temperatures up to 400 °F with a viscosity of 2,875 CPS at 375 °F, it offers excellent performance across multiple substrates with a 50-second open time for precise positioning.

The adhesive's high delivery rate capability makes it particularly well-suited for high-volume production environments where speed and efficiency are critical. With its long bonding range, 3M™ Hot Melt Adhesive 3738 provides flexibility in application timing while maintaining consistent bond strength across various materials. The thermoplastic nature allows for easy dispensing through compatible 3M hot melt applicators, and its general-purpose formulation helps streamline inventory by addressing multiple bonding needs with a single adhesive solution. Available in multiple stick sizes including Q, TC, PG, and AE formats, this adhesive integrates seamlessly into existing production workflows while delivering the reliability expected from 3M's industrial adhesive portfolio.
