CC2 is a type of nano level active precipitated calcium carbonate
upon surface treatment. The particle diameter is 40-80nm and the
shape of crystal is Cubic It has advantages such as high whiteness,
good dispersing performance, high surface activeness and regular
particles.
CC1 is a type of functional filler material exclusively used for
high standard silicon sealant, the latest development result of our
company, and a new product in the China Torch Plan
1) Applicable Characteristics: Used in the sealant system, it has
excellent thixotropic performance and system dispersing ability, as
well as the controllable system rheology and good filling and
reinforcement ability. It has not only well affinity with adhesive,
but also be able to improve the adhesive, tenacity, stretching
intensity and other dynamic performance to reach two functions of
both filling and reinforcement.
2) Applicable scope: Sealant materials of silicon, polysulfur,
epoxy and polyurethane, and silicon rubber products.
