NPCC-602, according to the special surface
making, is the Nanometer active calcium
carbonate, which is used as strengthening
agent and filling dose in series of sealed
mucilage glues like organic silicon,
polyurethane，
epoxy ，
PVC
resin, latex and so on. There are some
characters as following when used in
silicon and ketone sealed mucilage glues:
better complementing function, improving
the cohesion of glue, supplying better
changing capability, reducing the
pendulous speed, improving the effect of
opening cans and preventing sinking,
increasing extruding capability, providing
nice processing function, being easy to
disperse, substituting expensive silicon
dioxide, decreasing cost, production
techniques can be controlled and modified,
and can satisfy various requirements.
