silica powder is mostly used in the construction chemicals as well as recommended for texture coating & exterior finishing. The silica grades used in the coatings industry are produced synthetically and typically meet greater quality control standards, often having tighter physical-chemical requirements, such as color and brightness. Silica functions in paints and coatings as a great low-cost extender. silica is preferred for its chemical inertness which allows for good acid, chemical, and heat resistance. Along with its chemical inertness silica's hardness ameliorate abrasion resistance in paints. Silica powder has a tendency to improve the viscosity of coatings and paints, thus enhancing the convenience of using these materials.
In the coating and paint field:
Silica powder has very high purity resulting in highly consistent physical properties and particle size distributions. Their complete inertness and neutral pH, make the products not capable of altering or initiating reactions when incorporated in catalyzed or multi-component chemical systems.
Silica powder filler can be used in the following coating and paint industry field.
- Industry painting
- Wooding coating
- Anti-corruption coating
- Powder coating
- Architectural Paint
- Water-Proof Paint
Paint contriver, select small-sized industrial sands powder or grades to improve the appearance and longevity of architectural and industrial paint and coatings. In architectural paints, silica fillers improve tint retention durability, and resistance to dirt, mildew, cracking, and weathering. Silica’s low oil absorption allows increased pigment loading for improved finish color. In marine and maintenance coatings, the durability of silica imparts excellent abrasion and corrosion resistance.
Benefits of Silica powder used in painting products:
- For improved abrasion resistance and scratch-resistance of the film.
- Gives the highest chemical longevity in industrial coatings.
- Offers high loading level leads to reduced formulation costs.
- Hydrophobically modified grades of silica have also been used to improve corrosion performance and water repellency of coatings.
Other uses -
- Improve the early stage intensity of dry-mix, grouting.
- Acting as an anti-caking agent in fertilizer.
- Acting as a raw material of silicate brick
- Silica powder is widely used as a filling material and modifying agent.
- Making high crack-resistance, self-waterproofing concrete, be used in the subway, tunnel, and basement of high-rise structures.
- Making high-grade concrete effectively enhances the strength of strong concrete.
- Used in maritime works and chemical industry. Owing to the compatibility, it can prevent effectively sulfate and chlorine ion from osmosing and eroding.
- Effects on high-early strength concrete and strong concrete.
- Used in project items for water conservancy and bridge.
- Used in the construction item underwater, such as a pier, huge dam, and drilling platform.
- Used in road surface concrete of expressway and large-scale bridge.
silica improves the most important qualities in paints such as reflectance, brightness, and color consistency for any large-scale uses. Silica micro powder is made from high purity natural quartz and produced by means of particular cleaning and ironless ultrafine grinding. It's a reinforcement and replenishment filler for paint or coatings systems.
