Specification of Whole Silica hydrophobic nano silica fumed silica

Whole Silica hydrophobic nano silica (fumed silica) is a high-performance product developed for commercial applications calling for boosted longevity and water resistance. This product is made via a vapor-phase process, creating nanoparticles with a strong hydrophobic surface. It functions well in systems where wetness control is important.

The main bit size ranges from 7 to 40 nanometers. These fragments form aggregates, raising area up to 400 square meters per gram. The high surface boosts reinforcement in compounds. The hydrophobic therapy utilizes reactive silanes, guaranteeing low moisture absorption. This therapy prevents clumping and preserves stability in damp environments.

Pureness levels surpass 99.8%, with very little traces of hefty steels or contaminations. The product looks like a white, fluffy powder. It is free-flowing and very easy to spread in solvents, materials, or polymers. Its pH stays neutral, around 3.5 to 5.5, lowering chemical sensitivity in many formulas.

Applications include layers, adhesives, sealants, and elastomers. It enhances mechanical toughness and abrasion resistance in paints. In adhesives, it manages thickness and stops sagging. For silicone rubber, it boosts thermal stability and tensile properties. The hydrophobic nature makes it optimal for exterior products revealed to rain or moisture.

The product is likewise utilized in cosmetics and drugs. It works as a thickening agent in creams and lotions. In drugs, it assists in tablet stabilization. Its non-toxic profile ensures security in these applications.

Packaging options include 5-kilogram bags, 20-kilogram paper drums, or mass containers. Storage requires a dry, awesome setting below 25 ° C. Direct exposure to high moisture need to be stayed clear of to maintain performance. Life span is 24 months when kept properly.

Personalized fragment dimensions or surface area treatments are offered. Technical support is supplied to help incorporate the product right into certain formulations. Examining samples can be supplied upon demand.

Applications of Whole Silica hydrophobic nano silica fumed silica

Hydrophobic nano silica, called fumed silica, is a versatile material utilized across several sectors. Its water-repelling buildings make it perfect for applications where moisture resistance issues. In coatings and paints, it enhances durability by developing a protective layer. This layer quits water from destructive surfaces. It additionally helps protect against deterioration on steel structures.

Building and construction products take advantage of hydrophobic nano silica. Adding it to concrete or cement lowers water absorption. This makes buildings last much longer in damp environments. Fractures and weathering occur less typically. Roadways and bridges remain stronger in time.

Adhesives and sealers use this material to enhance performance. It enlarges products without altering their chemical makeup. Bonds remain strong also in high humidity. Voids remain secured against leakages.

The pharmaceutical market depends on hydrophobic nano silica too. It stops tablets from sticking together during manufacturing. Powders circulation smoothly in manufacturing. Tablet computers remain stable in packaging.

Automotive parts need protection from moisture. Hydrophobic nano silica is mixed right into rubber and plastics. Tires stand up to water damage. Engine components stay clear of rust.

Electronic devices gain from its protecting homes. Circuit card covered with it prevent short circuits caused by humidity. Gadgets function accurately in moist problems.

Textiles treated with this material drive away liquids. Fabrics dry much faster. Stains clean off conveniently. Outside gear remains water resistant much longer.

Cosmetics utilize hydrophobic nano silica to boost structure. Products feel smoother on skin. Make-up lasts much longer without smudging.

Individual care things like hair shampoos gain much better uniformity. They spread out evenly and rinse tidy.

Hydrophobic nano silica’s tiny bit size allows it blend right into several materials. It works without altering color or quality. Its flexibility makes it a key ingredient in contemporary production.

5 FAQs of Whole Silica hydrophobic nano silica fumed silica

Hydrophobic nano silica fumed silica is a fine powder treated to repel water. It is made by vaporizing silicon tetrachloride at high heat, creating tiny particles with strong water resistance. This material is used in coatings, adhesives, and composites where moisture protection matters. Its small particle size gives it high surface area, boosting performance in final products.

People often ask what makes this silica different from regular silica. The key difference is the hydrophobic treatment. Regular silica absorbs water, but this version keeps materials dry. This makes it ideal for outdoor applications or products exposed to humidity. The treatment also improves dispersion in polymers, preventing clumping.

Another common question is how much should be used in a formula. The amount depends on the application. For coatings, 1-5% by weight is typical. Higher amounts increase water resistance but might affect texture. Testing small batches first is recommended. Manufacturers provide guidelines based on the material’s role—filler, thickener, or additive.

Users also ask if it works with all types of resins or plastics. It is compatible with most common polymers like epoxy, silicone, and PVC. Some specialty plastics might need adjustments. Mixing it with polar resins requires extra care to avoid uneven distribution. Data sheets list compatible materials, but trial runs help confirm suitability.

Safety is a frequent concern. The powder is non-toxic but poses a dust hazard. Breathing protection is needed during handling. It is stable at room temperature and does not react with air. Spills should be swept up, not washed, to avoid spreading. Storage in sealed containers away from moisture keeps it effective.

Lastly, people wonder about shelf life. Unopened, it lasts over two years in dry conditions. Once opened, use it within six months for best results. Exposure to humid air reduces its hydrophobic properties over time. Keeping containers tightly closed after each use extends usability.
