In-House Adhesive Chemistry: Eliminating Concrete Blowouts & Core Delamination

2026-08-240

In high-pressure concrete casting—such as self-compacting concrete pumping in high-rise shear walls or massive dam construction—formwork failure often stems from adhesive breakdown under lateral hydrostatic loads. While most plywood factories rely on outsourced, diluted glues, NQ Formwork Plywood Co., Ltd. manufactures its own proprietary waterproof resin adhesives in-house.

The Science of High Core Bonding Strength
  • Elevated Solid Resin Content: Producing adhesives internally enables strict control over the solid polymer ratio, creating rigid cross-linked chemical bonds between each cross-laminated eucalyptus ply.

  • Hydrostatic Load Absorption: When wet concrete is pumped rapidly, our high-bond core absorbs lateral shear stress, preventing panel bulging and dangerous site blowouts.

  • Severe Boiling Water Endurance: Our standard panels endure continuous boiling tests without layer separation, securing 6 to 8 reuses for 12mm boards and 15 to 20 reuses for 18mm heavy-duty boards.

Quality Control Across Every Sheet
Raw Timber Peeling ➔ In-House Resin Coating ➔ High-Pressure Hot Pressing ➔ CNC Edge Trimming ➔ Phenolic Sealing

Every stage of our 30,000-sheet daily production is monitored to meet international engineering tolerances.
