Tecbond 523 All-Purpose Plasterboard Hot Glue Sticks

Power Adhesives Tecbond 523 is an economical, pale amber EVA adhesive designed specifically for v-groove applications in plasterboard and drywall fabrication. These 5/8" (15mm) glue sticks deliver a professional balance of adhesion, working time, and applicator output to support consistent, reliable bonds.

The adhesive viscosity allows it to flow effectively into porous surfaces, while the molten tack removes the need for extended holding or clamping periods. By replacing tapes, tacks, and screws, Tecbond 523 helps reduce fabrication time while forming a finished bond strong enough that the plasterboard will break before the adhesive fails.

Tecbond 523 Glue Stick Highlights

• Strong Bond Strength: Produces a finished bond robust enough that the plasterboard substrate will break before the adhesive fails.
• Optimized Viscosity: Flows effectively into porous surfaces to support deep penetration and reliable adhesion.
• Efficient Fabrication: Reduces working times compared to tapes, tacks, and screws by removing the need for extended clamping.
• Balanced Performance: Provides a controlled balance of adhesion, working time, and output for v-groove applications.
• FDA Compliance: Meets FDA 175.105 requirements for indirect food contact.
