  • Process and composition for insulation of surfaces, and product thereby obtained
    Patent number: 4442242
    Abstract: The invention relates to a process for insulating surfaces for the purpose of preventing or reducing occurrence of condensation on the surface, comprising applying to the surface a layer of a coating composition containing a binder and, distributed therein, granules of an expanded inorganic material having a bulk density of at least 150 kgs/m.sup.3. The invention also provides for a composition suitable for carrying out such process, comprising a binder and granules of an expanded inorganic material of the nature indicated.
    Type: Grant
    Filed: March 23, 1981
    Date of Patent: April 10, 1984
    Assignee: A.B. Bonnierforetagen
    Inventor: Ernst R. Fogelberg

  • Process and composition for minimizing accumulation of moisture on a cold surface exposed to humid conditions and product obtained thereby
    Patent number: 4364994
    Abstract: The accumulation of moisture on a cold surface exposed to humid conditions which tend to cause condensation on said surface is minimized by applying a coating to the surface which contains unoccluded, water-absorptive particles in admixture with a resinous binder in an amount sufficient to bind the particles together in a adherent coating on the surface, but insufficient to occlude the water absorptivity of the particles. The particles comprise a mixture of cellulosic fibers and water-absorptive, inorganic particles having a bulk density less than 150 kgs/m.sup.3.
