NCC-602 FOR ADHESIVE AND SEALANT
NCC-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 changging 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, substituing expensive silicon dioxide, decreasing cost, production techiniques can be controlled and modified, and can satisfy various requirements.
