Because of their solvent resistance, these materials find use as sealants to fill the joints in pavement, automotive window glass, and aircraft structures. Polymers containing one or two sulfur atoms separated by hydrocarbon sequences are usually not classified polysulfides, e.g. poly( p -phenylene) sulfide (C 6 H 4 S) n .
In 1838, Swiss chemists reported the preparation of hydrophobic rubbery materials by the alkylation of sodium polysulfide with 1,2-dichloroethane. [2] In 1926 chemists Joseph C. Patrick and Nathan Mnookin further developed this class of materials, which first achieved commercial success as sealants for fuel lines, exploiting the solvent resistance of these materials.
Backer rod, also called backer material or back-up rod, is a flexible foam product used behind caulking to increase elasticity, reduce consumption, force the caulking into contact with the sides of the joint creating a better bond, determine the thickness of the caulking, and define the cross-section hour-glass shape of the caulk. The backer ...
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 ...
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Metal waterstops are delivered in coils of up to 50 m with a typical dimension of 1.0 to 1.5 mm thickness and width of 250 to 300 mm. Splices can be welded, overlapped or joined with a sealant. A subcategory of metal waterstops is coated with polymeric and/or hydrophilic materials in order to provide a higher bond to the concrete and form a ...
Gel-Nimbus 25. With soft, cloud-like gel cushioning in the midsole, the Asics Gel-Nimbus 25 shoes have the stamp of approval from Anne Sharkey, D.P.M., a podiatrist at North Austin Foot & Ankle ...
