Summary

Reolosil, manufactured from highly purified chlorosilanes as raw materials under rigorous process control, is fumed silica powder composed of 5 to 50 nm primary particles.

Characteristics

Reolosil is microparticles manufactured by gas phase reaction, and forms loose agglomerates. By dispersing it moderately, it can be dispersed in particles smaller than the wavelength range of visible light.

Reolosil is available in various hydrophilic grades and hydrophobic grades produced from hydrophilic silica through hydrophobic surface treatment. According to the application objectives of the powder, Reolosil can be dispersed in various dispersion forms, including liquid and powder media.

Applications

Elastomers

The use of Reolosil as a reinforcing and bulking agent in elastomers such as silicon rubber contributes to greater strength and stretching properties.

Sealants (*1) 

The viscosity of a solvent can be adjusted by addition of Reolosil, giving it thixotropic properties (*2) (improvement in workability). In addition, other properties of elastomer strengths can also be increased through the use of Reolosil.

*1 Rubber-like materials used in the gaps between the frames and glass of windows to adhere and seal both sides.

*2 This refers to the property in which a material in an undisturbed static state resists flowing, but flows freely when force is increased. Paint is a specific example of this. When force is applied, paint can be spread for easy coating; but after coated, paint does not drip or sag.

Liquid resins

Reolosil is used for its anti-sagging properties and also to prevent the settling of pigments contained in paints, adhesives and other liquids.

Powders

Added to various powders, Reolosil improves the flowability of the powder and prevents the powder from caking.
