  • 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.

  • Adhesive composition adapted for setting at a time later than the time of application
    Patent number: 4497916
    Abstract: An improved sealing or adhesive composition comprising a stable slurry of solid meltable wax-like particles dispersed in a liquid adhesive or sealant composition, such as an anaerobic adhesive of sealant, which may be caused to cure at a time later than the time of application. The composition may be applied to threaded bolts or other articles by pumping the slurry through a heated applicator head to dispense homogeneous liquid on the article which hardens on cooling to a non-mobile setable coating.
