WHISCAL increases the mechanical strength and elastic modulus of the resin containing it by an effect of its shape (whisker-like shape).
A smooth molded surface can be obtained thanks to its fine size.
It gives isotropic physical and optical properties to the molded items for its poor particle
orientation.
It can prevent the cracking of coatings because it has micro-reinforcement effects.
It cal also prevent the swelling and peeling of coatings.
It gives an appropriate viscosity and thixotropy to resins.
It gives a thinning prevention effect and adhesiveness to putties.
It gives excellent drying properties to various paints.
It can be easily dispersed with a simple disper.

*Cautions during use
Because WHISCAL is made of calcium carbonate, even if it is absorbed inside of the lung, it is easily dissolved, therefore, it is recognized as a safe whisker material, however, be sure to wear a dust-protective mask, etc. to take extra caution to avoid inhaling.
