  • Coating compositions containing chemically modified amorphous polyolefins, a process for coating plastics with these compositions and the coated plastics produced therefrom
    Patent number: 5274039
    Abstract: The present invention relates to a coating composition which contains a one- or two-component binder and, in addition, an adhesion promoter which is based on a chemically modified, amorphous polyolefin having an average molecular weight M.sub.w (weight average) in the range from 10,000 to 100,000 g/mol, a non-uniformity U.sub.n of 1.0 to 6.5, a chlorine content of about 2.5 to 50% by weight and a total content of nitrogen, oxygen, sulfur and silicon, in the form of chemically incorporated functional groups, of about 2.5 to 15.0% by weight.The present invention also relates to a process for coating plastic substrates with this coating composition and to the coated plastic substrates obtained in accordance with this process.

  • Process for the production of back foamed internal parts for refrigeration furniture
    Patent number: 5269986
    Abstract: Refrigeration units having internal parts containing a rigid polyurethane foam formed without the use of perhalogenated fluoro-chlorohydrocarbons are produced by applying a coating to the internal walls of the part in which back-foaming will take place, pouring a foam forming reaction mixture into the cavity of the part in which the internal walls have been coated and allowing the foam to form and set. The coating applied to the internal walls of the part in which back foaming is to be carried out is selected from one-component chemically cross-linking lacquers, two-component chemically cross-linking lacquers and lacquers based on aqueous polyurethane dispersions. The foam forming mixture generally includes a polyisocyanate, a polyisocyanate-reactive compound and a blowing agent. The blowing agent must include a partially halogenated hydrocarbon having at least one carbon-hydrogen bond and a boiling point in the range of from about -50.degree. to about 50.degree. C.
