Description:
Dextrin Yellow is a modified starch product obtained from the partial hydrolysis of starch, typically using heat and acid. It is characterized by its yellow to light brown appearance and is commonly used in industries as an adhesive, thickener, and binding agent. Dextrin Yellow differs from other types of dextrins due to its higher degree of roasting, giving it unique adhesive properties and a yellowish hue. It is widely used in adhesives, textiles, food processing, and the paper industry.
This versatile product is valued for its ability to form strong bonds, dissolve in water, and enhance texture in various applications.
Applications:
- Adhesives:
- Extensively used in the formulation of water-soluble adhesives for paper products, cartons, envelopes, labels, and stamps.
- Acts as a key component in remoistenable glues.
- Textile Industry:
- Applied as a finishing agent or sizing agent in textile manufacturing to add stiffness and improve fabric handling.
- Used in textile printing as a thickening agent for printing pastes.
- Paper and Packaging Industry:
- Serves as a binding and adhesive agent in paper and packaging products, including corrugated boxes, gummed tapes, and paper bags.
- Food Industry:
- Can be used in food products as a thickener, stabilizer, or coating agent, though more common in non-food-grade applications.
- Foundry:
- Functions as a binder in sand casting molds for metal casting, providing strength to the mold and ensuring detailed castings.
- Pharmaceuticals and Cosmetics:
- May be used as a binder or excipient in tablet formulations and certain cosmetic products.
- Pyrotechnics:
- Utilized as a fuel or binder in the manufacture of fireworks and other pyrotechnic compositions.
Benefits:

Handling and Storage:
- Handling:
- Avoid inhaling dust during handling as it may cause respiratory irritation.
- Use appropriate personal protective equipment (gloves, masks, goggles) when handling large quantities.
- Prevent direct contact with eyes and skin. In case of eye contact, rinse with water and seek medical attention if irritation persists.
- In case of spillage, sweep or vacuum up the material and avoid creating airborne dust.
- Storage:
- Store in a cool, dry area in tightly sealed containers to prevent exposure to moisture, which may cause caking.
- Keep away from direct sunlight, heat sources, and strong oxidizing agents.
- Avoid storing in humid environments as moisture can affect the product’s adhesive properties.
- Ideal storage temperatures are between 10°C and 30°C (50°F and 86°F).
- Shelf life is generally 12-24 months under proper storage conditions.
