High-Performance Paper Sizing & Coating Dextrin
KAGDEXT-W (White Dextrin) | SEVAGRAM EXCIPIENTS
In modern paper and paperboard manufacturing, surface quality, printability, strength and coating efficiency are critical for producing competitive grades. KAGDEXT-W, Sevagram Excipients’ white dextrin, is a heat-modified starch derivative designed to meet the evolving requirements of paper sizing, coating, adhesives and surface treatments where thin viscosity, smooth flow and excellent film formation are essential.
Manufactured at our facilities in Maharashtra, Sevagram Excipients is one of India’s largest producers and exporters of speciality and modified starches, serving paper mills, board manufacturers and industrial processors across India and global markets
What is White Dextrin?
White dextrin is produced by roasting starch in the presence of acid, which chemically transforms the starch molecules into a partially depolymerized, water-soluble adhesive polymer. Unlike native starch, which requires full gelatinization, dextrins dissolve easily and form low-viscosity, high-solids adhesive solutions.
White dextrin is characterized by:
- Fine, free-flowing powder
- White to off-white appearance
- Controlled solubility
- High film-forming capability
- Strong bonding at low application weight
These properties make white dextrin ideal for paper sizing, coating, board adhesives and surface treatment processes where high solids and smooth flow are required.
KAGDEXT-W is Sevagram’s paper-grade dextrin, engineered to perform consistently in high-speed paper and board machines.
Why Paper & Board Mills Prefer KAGDEXT-W
Paper and board manufacturers require binders that deliver strength, surface smoothness and printability without increasing coating viscosity or machine load. KAGDEXT-W addresses these needs precisely.
Key Performance Benefits
KAGDEXT-W delivers the following advantages in paper and board production:
- Enhances paper strength by forming strong starch-based bonding films
- Faster setting compared to native starch adhesives
- Improves surface smoothness, supporting superior coating quality
- Significantly improves printability by reducing ink feathering and absorption irregularities
- Excellent solution stability with high flow and spread properties
- Fine white powder with consistent solubility behaviour
- Improves oil absorbency, making it suitable for high-quality printing papers
These features allow paper mills to achieve better sheet formation, sharper print definition and improved runnability without increasing binder consumption
Once applied, KAG-SIZE enters the yarn matrix and bonds effectively with individual fibers. This internal reinforcement reduces surface brittleness, minimizes flaking and droppings, and ensures that the sizing is not visibly noticeable in the final fabric feel. As a result, fabrics maintain a natural handle while benefiting from improved weaving performance.
Applications of KAGDEXT-W in the Paper Industry
KAGDEXT-W is specifically positioned for paper, board and packaging manufacturers seeking thin-viscosity, high-performance starch binders.
Surface Sizing of Paper
KAGDEXT-W is widely used in surface sizing where it:
- Improves surface strength
- Reduces dusting and picking
- Enhances ink holdout
- Improves print clarity
Thin-viscosity dextrin allows uniform application even at high machine speeds.
Paper Coating Adhesive
In coating formulations, KAGDEXT-W works as a low-viscosity adhesive binder, allowing:
- Higher pigment loading
- Better coating smoothness
- Improved coating hold
- Faster drying
This makes it ideal for writing paper, printing paper and specialty coated grades.
Paperboard & Carton Coating
White dextrin improves:
- Surface stiffness
- Ply bonding
- Coating integrity
- Carton print quality
It is widely used in duplex board, folding box board and packaging paper.
Paper Tube, Label & Bottle Gum Adhesives
Because of its fast tack and clean drying, KAGDEXT-W is also used in:
- Label gums
- Bottle label adhesives
- Paper tube and core adhesives
These applications benefit from dextrin’s high solid content and excellent binding capability
Compatibility with Sevagram’s Paper Starch Portfolio
KAGDEXT-W is part of Sevagram Excipients’ complete paper & board starch system, which includes:
- KAGSTAR (Oxidized Starch) for surface sizing & coating
- KAG-CAT (Cationic Starch) for wet-end strength & retention
- KAGSPRAY (Spray Starch) for board ply bonding
- KAGDEXT-W (White Dextrin) for thin-viscosity surface adhesives
This allows paper mills to source all starch-based binders and strength agents from a single, reliable manufacturer, ensuring process compatibility and performance continuity
Technical Characteristics
White dextrin used in the paper and board industry is derived from maize or tapioca starch and processed to meet industrial quality norms. Typical properties include:
- Free-flowing white powder
- Controlled cold-water solubility
- Low ash content
- Consistent particle size
- Stable acidic pH
- High solid-loading capacity
These characteristics allow high-solids, low-viscosity adhesive solutions that outperform many synthetic resins in paper applications
Packaging and Supply
KAGDEXT-W is available in:
- 25 kg bags
- 50 kg bags
- Jumbo bags
Packaging materials:
- HDPE woven bags with liners
- Paper bags
This ensures safe storage, easy handling and contamination-free supply for bulk paper mills and converters
