Tecbond 550 Low Viscosity Plasterboard & Drywall Hot Melt Glue Sticks

Power Adhesives Tecbond 550 Low Viscosity Plasterboard Adhesive Hot Melt Glue Sticks

Tecbond 550 is an EVA-based adhesive developed for large-scale plasterboard and drywall fabrication where consistent output and strong bonds are required. These 5/8" (15mm) hot melt glue sticks deliver a lower viscosity and higher output formulation than previous versions, supporting tighter joins and efficient application.

The low viscosity formulation allows the adhesive to flow deeply into porous surfaces, while very high molten tack provides near-instant holding power without the need for clamping. This combination supports fast assembly cycles and produces durable bonds suitable for high-throughput plasterboard fabrication environments.

Tecbond 550 Series Highlights

• Low Viscosity Formulation: Flows into porous surfaces to increase physical bond strength.
• High Molten Tack: Provides an almost instant hold to eliminate extended clamping periods.
• Enhanced Output: Formulated to deliver higher applicator output for efficient workflows.
• Superior Strength: Produces bonds strong enough that the substrate will fail before the adhesive.
• 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.
