Joint compound providing low dusting and good gloss retention |
摘要 |
The present invention provides a low dusting joint compound comprising a filler, a binder, a thickener and one or more synthetic polymeric waxes that are at least slightly soluble in water and are solid at room temperature. Preferably the wax includes a high molecular weight polyethylene glycol or methoxy polyethylene glycol having an average melting point of from about 80° F. (27° F.) to about 150° F. (80° C.). These additives impart low dusting properties without a sticky or oily feel. High molecular weight synthetic waxes also act as an internal binder to hold the joint compound together and improves paint gloss retention. The invention results in a joint compound with improved properties for drywall finishing.
