Power Adhesives Tecbond 550 Hot Glue Sticks

Tecbond 550 Low Viscosity Plasterboard Hot Glue Sticks

Power Adhesives Tecbond 550 hot melt glue sticks are an EVA-based adhesive engineered for large-scale plasterboard and drywall fabrication where strong, consistent bonds are required. These 5/8" (15mm) glue sticks feature a low viscosity, pale amber formulation that flows easily into porous surfaces to enhance physical bond strength.

Designed for tight joins and high-output applications, this formulation delivers improved flow compared to earlier generations while maintaining very high molten tack. The fast grab minimizes the need for clamping and produces a durable bond that supports reliable plasterboard assembly.

The Benefits of Tecbond 550 Hot Glue Sticks

• High Strength Bonding: Flows into porous surfaces to form a bond that exceeds the strength of the substrate.
• Fast Setting Time: Very high molten tack delivers an almost instant hold without extended clamping.
• Improved Penetration: Low viscosity formulation supports effective flow into tight joins and materials.
• Optimized Application: Designed for higher output to support efficient plasterboard fabrication.
• FDA Compliance: Meets FDA 175.105 requirements for indirect food contact.

Glue Sticks Per Carton

• 11 lbs of 5/8" × 12" glue sticks is approximately 95 glue sticks.
