Carboxymethyl Starch (Adhesives & Sizing)

Top Applications & Customer Pain Points

1. Paper & Corrugated Box Adhesives

Paste Sedimentation & Inconsistency : Native starches settle in corrugation gum tanks, causing pump blockages and downtime.
Poor Fines/Filler Retention : Loss of fines or clay increases raw-material cost and wastewater load.
Variable Viscosity : Fluctuating rheology leads to uneven glue lines and delamination.

2. Textile Warp Sizing

Yarn Breakage & Abrasion : Inadequate sizing reduces loom efficiency and raises waste.
Uneven Film Formation : High-viscosity sizes coat only surface of yarn; low viscosity penetrates too deeply, weakening the film.
Batch Lumping & pH Drift : Lumps block spray jets and cause batch-to-batch inconsistency.

Key Benefits :

Stable Suspension: Prevents starch settling in corrugation and paper-machine gum systems.
Improved Retention: Cuts fines and filler loss, reducing raw-material and treatment costs.
Consistent Rheology: Uniform viscosity for smooth, even glue lines and size applications.
Enhanced Fabric Performance: Raises warp sizing efficiency—stronger, less abrasive yarns.
Rapid Dispersion: Cold-water soluble for quick batch prep—minimizes production delays
Broad Compatibility: Effective across pH 8–11; works with hard or soft water.

Pain Point	Shalbond CMS Advantage
Paste Sedimentation & Pump Clogs	Negatively charged CMS keeps native starch in stable suspension.
Low Fines/Filler Retention	Enhances retention by up to 30% through ionic attraction of anionic fines.
Viscosity Drift	Controlled DS (0.05–0.10) maintains Brookfield viscosity 500–3000 cP.
Yarn Breakage & Poor Abrasion Resistance	Uniform film improves abrasion resistance by up to 20% and reduces breaks.
Uneven Film Penetration	Optimized molecular weight balances penetration and surface coating.
Batch Lumping & pH Variability	Cold-water solubility in <3 min; alkaline pH 8–11 maintains batch stability.
