We are the stalwarts in the domain of manufacturing, supplying, wholesaling, and exporting Silicon Dioxide (Erosil – NV/200)  
Silicon dioxide (SiO₂), commonly known as silica, plays several roles in poultry and animal feed applications due to its unique properties. Here are some of its uses and applications:
1. Flow Agent / Anti-Caking Agent

Primary Use: Silicon dioxide is widely used as an anti-caking agent in feed formulations. It helps prevent clumping or sticking together of powdered and granular feed materials, ensuring free flow of the feed, especially in humid conditions.

Application: By keeping the feed dry and free-flowing, it enhances ease of processing, storage, transportation, and dispensing of feed.

2. Carrier for Vitamins and Additives

Primary Use: SiO₂ can act as a carrier for liquid feed additives, vitamins, and enzymes. Its porous structure allows it to absorb these substances, converting them into a free-flowing powder form.

Application: This is particularly important in feed formulations where liquid additives are difficult to handle or need to be evenly distributed throughout the feed.

3. Digestive Health

Possible Benefit: Some studies suggest that small amounts of silicon dioxide in animal feed may support overall digestive health and nutrient absorption in animals. It is thought to contribute to the structural health of bones and connective tissues, though this is less commonly emphasized in feeds.

4. Binder in Pelletized Feeds

Primary Use: Silicon dioxide may also be used as a binder in pelleted feeds to improve the structural integrity of pellets, making them more durable and resistant to breaking during handling or transportation.

Application: This helps in maintaining pellet quality, ensuring that the animals consume feed in a form that delivers balanced nutrition without waste.

5. Safety and Regulatory Approval

Silicon dioxide is generally recognized as safe (GRAS) by regulatory bodies like the FDA and EFSA when used in controlled amounts, making it suitable for use in animal feed formulations.

In summary, silicon dioxide’s primary function in poultry and animal feed is as an anti-caking agent, flow enhancer, and carrier for additives. Its role ensures that feed remains in optimal condition for storage, distribution, and consumption, ultimately supporting the efficient nutrition of animal.

FUMED SILICA (Grade: Erosil NV/200 XL 5M) is a highly pure, synthetic amorphous silica with extremely fine particle size and high surface area. It offers several functional benefits in paints, inks, and coatings due to its unique physical and chemical characteristics.

USES & APPLICATIONS in PAINTS, INKS & COATINGS: 1. Rheology Control / Thixotropy Agent:
  • Acts as an anti-settling agent and sag control additive.

  • Provides shear-thinning behavior — becomes fluid during application (brushing/spraying) and thickens upon standing.

  • Helps maintain uniform dispersion of pigments and fillers in paints and inks.

2. Anti-Sagging & Anti-Sedimentation:
  • Prevents pigment settling during storage.

  • Enhances stability in solvent-based, water-based, and UV-curable coatings.

3. Thickening Agent:
  • Builds viscosity without significantly affecting gloss or transparency.

  • Useful in both low- and high-pigment formulations.

4. Matting Agent (in specific systems):
  • Imparts a matte or satin finish to clear coatings without using conventional matting agents.

5. Scratch & Abrasion Resistance:
  • Improves surface hardness and resistance to mechanical wear.

  • Enhances durability in industrial and automotive coatings.

6. Anti-Cratering & Anti-Flooding:
  • Prevents surface defects such as craters, fisheyes, and pigment floating.

  • Stabilizes formulation during drying and curing processes.

7. Dispersion Stability:
  • Helps in uniform pigment distribution and long-term storage stability.

  • Works synergistically with other additives for stable dispersions.

8. Gloss Control:
  • Used to adjust surface finish (from high gloss to matte) when used with other functional additives.

🔧 Typical Application Areas:
  • Industrial coatings (epoxy, PU, alkyd-based)

  • Automotive coatings

  • Decorative paints

  • Printing inks (gravure, flexo, screen)

  • Wood coatings & varnishes

  • Coil coatings
