  • Process for the production of foams
    Patent number: 4070310
    Abstract: This invention relates to a process for the production of polyurethane foams in closed molds using mixtures of organic polyisocyanates with certain compounds which liberate carbon dioxide under the catalytic influence of basic compounds. In this process a mixture of polyisocyanates and compounds which liberate carbon dioxide under the catalytic influence of basic compounds is reacted with organic compounds containing hydrogen atoms which are reactive with isocyanate groups, which organic compounds are mixed with basic compounds and/or have basic compounds chemically built into them. The process is suitable for the production of any polyurethane foams in a closed mold, but is preferably applied to the production of semi-hard and particularly of hard polyurethane foams having a dense outer skin.

  • Signal coating suitable for lead-based paint hazard abatement or the like and formulations therefor
    Patent number: 4067840
    Abstract: Protective coatings, such as paints and liquid formulations therefor, containing a masked chromogen which signals contact with a body fluid when the protective coating is masticated or ingested are disclosed. The chromogen is capable of producing a contrasting color when masticated and/or ingested, thereby signaling that the individual who masticated and/or ingested the chromogen may have ingested an undesirable or hazardous substance, e.g., a lead-based paint, that has been covered by the protective coating. The chromogen is substantially indiscernible in the paint and converts by reaction with an activator substance, e.g., by reaction with saliva, gastric juices, or the like, to a colored form which then stains the body fluids and/or the body tissues, and which may also stain the original source of the undesirable substance.
