Embodiments provide methods of disassembling apparel products. The methods include exposing an adhesive of the apparel product to a composition having an acidic or basic pH. The adhesive is disposed at least partially between a major component and a minor component of the apparel product. The adhesive includes a material having a disulfide bond. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion configured to be coupled to the major component with the adhesive. The methods include separating the major component from the minor component adjoined by the adhesive.
摘要:
The present invention relates to a novel aromatic polysulfide and an asphalt composition containing the same, and more particularly, to a novel aromatic polysufide having repeating units of the following formula (I), an asphalt composition, an asphalt paving composition, an adhesion promoter and an UV absorber containing the same: The asphalt paving composition of this invention exhibits excellent adhesiveness to aggregate component and better water resistance, and renders the temperature susceptibility less sensitive, thereby greatly improving durability.
摘要:
The use of benzoate plasticisers in two-component insulating glass adhesives/sealants based on polysulfide polymers or polymercaptan polymers enables simpler production due to the low viscosity thereof. Improved miscibility of the two components and an improved rate of curing are observed. In addition, the use of phthalate plasticisers, which may possibly cause an endocrinal effect in humans and animals, is avoided.
摘要:
Curable liquid polymers selected from mercaptan-terminated polysulfide polymers, polyepoxides and oganosilicon polymers are extended by mixing therewith, prior to curing 10% to 200% by weight, based on the weight of liquid polymer, of an aqueous colloidal dispersion selected from aqueous alkali metal silicates having an M.sub.2 O:SiO.sub.2 ratio of 0:1 to 1:1 and aqueous magnesium oxide. Upon curing of the mixture to solid form, nearly all of the water of the aqueous dispersion remains bound in the solid cured material and little, if any, shrinkage occurs.

A POLYSULFIDE POLYMER IS REACTED WITH ABIETIC ACID AND IS EFFECTIVE AS AN ADHESIVE ADDITIVE FOR A POLYSULFIDE POLYMER-BASED COMPOSITION USED AS SEALANTS OT BONDING AGENTS ON VARIOUS SUBSTRATES SUCH AS GLASS OR ALUMINUM.
摘要:
Adhesive compositions for medical and non-medical uses are provided. The adhesive compositions can include cyclic disulfide monomers, oligomers of reactions between the cyclic disulfides, polymers of the cyclic disulfides, solid articles formed from the polymers, and any combination thereof. Methods of making, using, and recycling the adhesive compositions are provided, including use of the adhesive compositions on a variety of substrates that include biological tissue; biomaterials, including synthetics and natural such as bone, wood, and cellulosics; metals and alloys; polymers, plastics, and rubbers; ceramics; composites; and, any combination of these materials. The adhesives can adhere to substrates in a variety of environmental conditions that include ambient atmospheric conditions, wet conditions that include adhering materials underwater, and in a wide variety of temperatures and pressures, such as those temperatures and pressures found in medical environments, including in living tissue, as well as many residential, commercial, industrial, and manufacturing environments.
