  • Gas line sealing method utilizing penetrating flexible sealant
    Patent number: 4731982
    Abstract: A method of sealing leaking gas pipe joints by injecting a catalyzed acrylic monomer composition into the leaking joint and curing the composition in the joint to seal the leak is characterized in that the composition when cured has a glass transition temperature which is no more than 0.degree. C. and is at least about 5.degree. C. below the minimum pipe joint operating temperature. Suitable sealants are mixture of long chain monoacrylic esters, hydroxy functional acrylic esters, acid monomers, plasticizers and polyfunctional acrylic esters.

  • Heating/cooling coil sealing
    Patent number: 4521453
    Abstract: A method of sealing a porous heating or cooling jacket of a reactor vessel includes the steps of: (a) draining the heating or cooling fluid from jacket; (b) washing and drying the interior of the jacket; (c) filling the jacket with a curable liquid sealant composition under pressure sufficient to cause the composition to permeate the porous areas in the jacket but insufficient to burst the jacket, the composition being curable at temperatures between about 75.degree. C. and 100.degree. C.; (d) draining the sealant from the jacket; and (e) heating the jacket to or above the cure temperature of the composition and maintaining that temperature for sufficient time to ensure total polymerization of the reactant composition.
