AGC Chemicals Americas, Inc. RESIFA™ SOLESPHERE™ L-31 is a synthetic spherical silica with low cohesiveness and high fluidity. SOLESPHERE™ L-series has a lower specific surface area than the H-series grades. It is suitable for chemical surface modification or coating. Despite the difference in surface area, the L-series products keep the same oil absorption capacity as the H-series. It also offers better slipperiness and spreadability than the H-series. Because of the product's porosity, it has a light scattering effect for cosmetics and acts as a matting agent for coatings. Its particle size distribution is narrow, and hence it can give a single asperity to a thin coating layer.

Formulating with SOLESPHERE™ Silica

SOLESPHERE™ provides excellent formulation flexibility as it can be added to any phase of the formulation. Through product and application testing, it has been shown SOLESPHERE™ silica provides the same effects in the formulation regardless of whether they are added to the water phase/aqueous phase, oil phase, or even if added at the very end.

  • The effects of the silicas will show with just 1% added, however, adding more can increase benefits. 2-2.5% is the typical loading level.
  • It is not recommended to add more than 3-4% in total silica content. This can result in the formulation appearing “chunky.”
  • Multiple SOLESPHERE products can be added to a formulation to achieve different desired goals, but it is important to not go over the 3-4% total.
  • Significant SPF boosting with H-53 and H-52 will show with just 1-2% added.
Application Information

Cosmetics and Personal Care

SOLESPHERE™ silica gels are used as additives in cosmetic and personal care applications such as make-up, skin care products, deodorants and fragrances.

Resins and Polymer Compounds

When added to polymer formulations, SOLESPHERE™ silica gels offer anti blocking and improved dielectric insulation properties. SOLESPHERE™ also provides good UV and hardness properties as an additive for 3D resins.

Catalyst Supports

SOLESPHERE™ is used as a catalyst support carrier particularly with polyolefin manufacturing processes.

Paper Coating

By adding SOLESPHERE™ to paper coating formulations, surface hardness can be increased and matting effect improved.


SOLESPHERE™ silica gels are used to improve the matting effect in coatings, as a thickener for paints, and for specialized paints for electronic materials.
