Stardex® 2155 – Angle Board

Premium Tapioca-Maize Blend Adhesive Powder for Angle Board Manufacturing

A carefully engineered blend of tapioca and maize-based modified starches designed specifically for high-speed angle board lines. It delivers the ideal balance of open time, green tack, and final compression strength that forward-thinking manufacturers demand.

Angle board (paper edge protectors) must withstand significant stacking loads, strapping tension, and transit impacts while maintaining dimensional stability. Stardex® 2155-Angle Board addresses the two most critical performance parameters — Open Time and Compression Strength — through precise control of viscosity, water retention, penetration behavior, and film-forming properties.

Key Benefits

Optimized Open Time

Engineered for a wide, controllable bonding window that supports high-speed lamination without premature drying or excessive slip. This prevents delamination during compression and enables reliable operation even on faster lines.

Superior Green Tack and Initial Bond Strength

Develops strong ply adhesion immediately after lamination, reducing rejects and allowing boards to hold shape during handling and early curing stages.

Exceptional Compression Strength

Creates a rigid, fiber-anchored network between plies that significantly enhances edge crush, flat crush, and vertical load-bearing capacity — critical for warehouse stacking and transport protection.

Efficient Penetration Control

Balances surface tack with controlled fiber penetration to form strong mechanical anchoring without starving the glue line or creating weak surface-only bonds.

High Film Strength After Drying

Forms a tough, flexible-yet-rigid starch film that boosts overall board rigidity and crush resistance.

Low Consumption & Cost Optimization

Higher solids content and excellent adhesive efficiency typically reduce usage per ton of finished board compared to standard native or single-base starches.

Batch-to-Batch Consistency

Tight viscosity control ensures stable machine runnability, minimal adjustments, and predictable performance.

Fast Drying Under Pressure

Supports rapid curing without compromising bond quality, improving overall line productivity.
