Gypsum Board Starch (Drywall & Plasterboard)

Core Customer Pain Points & Shalbond Solutions

• Weak Core-Paper Adhesion : Native starches fail to migrate uniformly, causing liner separation and rejects.
  Shalbond Fix : Enhances interfacial hydrogen bonding via controlled acid-modification; achieves ≥95% fiber-tear on peel tests.
• Inconsistent Viscosity & Batch Variability: starches exhibit viscosity spikes or premature gelation, leading to uneven board properties.
  Shalbond Fix: Precisely tuned peak-gel viscosity (20–30 cP) and cold-water dispersion (< 3 min) for repeatable, shift-long stability.
• low Dry-Cycle & Energy Waste: Excess water retention in core prolongs dryer use, inflating energy costs.
  Shalbond Fix: Optimized hydrophilicity balances water migration—shortening dryer residence by up to 10% and reducing fuel consumption.
• Core Strength & Nail-Pull Deficiencies: Inadequate starch distribution yields low edge strength and core cracking.
  Shalbond Fix: Promotes uniform gelatinization and migration, boosting nail-pull by 15% and compressive strength by 10%.
• Process Integration & pH Sensitivity: New binders often demand pH or equipment adjustments.
  Shalbond Fix: Neutral to mildly acidic (pH 5–7) compatibility—no hardware changes or chemical balancing needed.

Key Benefits :

• Superior Bond Integrity — Consistent 95–100% fiber-tear adhesion on liner peel tests
