Shiraishi Kogyo Kaisha Viscoexcel-30 is a ultra-fine calcium carbonate which has 30 nm of particle size. These particles are surface coated with fatty acid to improve dispersion property at the mixing. Viscoexcel-30 is developed and designed as calcium type rheologicalmodifier. Viscoexcel-30provides high viscosity and high thixotropicproperty, the same as fumed silica or organic agent. Viscoexcel-30provides better rheologicalproperty both at low and high shear area, also provides better workability at high shear area.

Shiraishi Kogyo Kaisha Hakuenka CC is our original Ultra-fine precipitated calcium carbonate coated with organic compounds. It was originally developed for reinforcing rubber materials in the early 20th century. Hakuenka CC has 50 nm uniformed ultra-fine particles as primary particle. These particles are surface treated with fatty acid in order to improve dispersion property at mixing stage with organic materials. Hakuenka CC is specially applied for construction application where Silicone & Polysulfide sealants are used. Hakuenka CC is commonly used as other application such as rubber, plastics and so forth.
