Gypsum Board Starch (Drywall & Plasterboard)

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
  • Stable Rheology — 20–30 cP Brookfield viscosity (20 °C) remains stable over 8 hr runs
  • Rapid Dispersion — Cold-water soluble, lump-free in < 3 minutes for seamless batching
  • Energy & Cost Savings — Up to 10% shorter drying cycles; 5–15% lower starch usage
  • Enhanced Core Performance — +15% nail-pull strength; +10% compressive strength for durable wallboards
