  • 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.
