Butyl rubber sealant is used for damp proofing, rubber roof repair and for maintenance of roof membranes (especially around the edges). It is important [ citation needed ] to have the roof membrane fixed, as a lot of fixtures (e.g., air conditioner vents, plumbing, and other pipes) can considerably loosen it.
The second active ingredient is an organic solvent such as 2-butoxyethanol (ethylene glycol monobutyl ether, trade name butyl cellosolve) that acts as a wetting agent and provides a protective primer layer in conjunction with an organic polymer emulsion.
Sealant is a substance used to block the passage of fluids through openings in materials, [1] a type of mechanical seal. In building construction sealant is sometimes synonymous with caulk (especially if acrylic latex or polyurethane based) [2] and also serve the purposes of blocking dust, sound and heat transmission. Sealants may be weak or ...
Parts would then be covered with sealant, and positive pressure applied. More energy would be required to penetrate the porosity with sealant than to evacuate the air. The operator would then release the pressure and drain the chamber. Excess Sealant Recovery: The operator would remove excess sealant through gravity, rotation or centrifugal force.
Butyl acrylate is an organic compound with the formula C 4 H 9 O 2 CCH=CH 2. A colorless liquid, it is the butyl ester of acrylic acid. ... coatings, adhesives, fuel ...

Polysulfide polymers are insoluble in water, oils, and many other organic solvents. Because of their solvent resistance, these materials find use as sealants to fill the joints in pavement, automotive window glass, and aircraft structures.
