摘要:
A two-part adhesive composition exhibiting improved elasticity wherein its composition includes one or more acrylate or methacrylate ester monomers, a sulfur bearing compound, preferably a sulfonyl chloride, an amine promoter, preferably, an amine aldehyde reaction product, and a thermoplastic block copolymer component selected from the group consisting of a. a linear styrene-butadiene-styrene copolymer b. a radial styrene-butadiene-styrene block copolymer with a plasticizer, c. a linear or radial styrene-isoprene-styrene block copolymer, and d. a linear or radial styrene-butadiene-isoprene-styrene block copolymer, and mixtures thereof.
摘要:
The present invention relates to a low VOC solvent based adhesive comprising a mixture of at least two organic solvents and a thermoplastic resin. Desirably the adhesive has a flash point of at least 100.degree. F. when measured in accordance with ASTM D3828-87. The solvent blend of the low VOC solvent based adhesive of the instant invention volatilizes at substantially reduced rates as compared to conventional solvent blends in solvent based adhesives. Furthermore, this novel low VOC solvent based adhesive is easy to apply, cost effective, and cures within a reasonable time without the use of heat, ultraviolet light or other mechanical devices. In addition, the novel low VOC solvent based adhesive has good storage stability in metal or non-metal containers.
摘要:
A curable urethane adhesive composition having a high green strength consisting essentially of a mixture of an isocyanate terminated ricinoleate prepolymer and chlorinated polyvinyl chloride curable by reaction with compounds having reactive hydrogens such as water, amines, polyols, urethanes, ureas and the like.
摘要:
A SOLUTION OF POST-CHLORINATED POLYVINYL CHLORIDE RESIN IN TETRAHYDROFURAN, AN ADHESIVE, IS STABILIZED AGAINST GELLING BY INCLUDING THEREIN A SMALL AMOUNT OF 1,2-BUTYLENE OXIDE, ETHYL ACETATE OR MIXTURES THEREOF.
摘要:
Low polymerized halogenated polyvinyl chlorides which are obtained according to the parent Specification by further chlorination of polyvinyl chlorides in the presence of solvents or agents promoting the formation of suspensions are used as a basis for adhesives, particularly for leather cements. The compounds may be used as such, or admixed with other adhesives, or with the addition of solvents e.g. acetone, methyl, ethyl and butyl acetates or mixtures thereof with benzine, benzene or toluene; softening agents e.g. phthalic esters, ethyl acetanilide; natural and artificial resins e.g. fine resin and copal; pigments, fillers and fibrous materials e.g. iron oxide, zinc oxide, chromic oxide, wood meal, asbestos powder or fibres. According to an example, a leather cement is obtained by dissolving 20 pts. by wt. of low polymerized polyvinyl chloride in 80 pts. by wt. of methylene chloride.
摘要:
The present disclosure provides a PVC or CPVC solvent cement and a composition for forming a PVC or CPVC coating on an object. The solvent cement and the coating composition each include one or more caprolactam-derived solvents and a polymer selected from the group of polyvinyl chloride and chlorinated polyvinyl chloride. The one or more caprolactam-derived solvents include a linear alkyl group of 1, 2 or 4 unsubstituted carbons or an alkoxymethyl group of 2 or 3 unsubstituted carbons bonded to a nitrogen heteroatom.
