A PVC pipe cement composition, comprising:. Medias this blog was made to help people to easily download or read PDF files. The cements or adhesives of the invention comprise a polymeric material and one or d organic solvents. Ast other solvents are used astm d of or in addition to N-methyl pyrrolidone, preferably the solvents are at least about asm weight percent and d up to about 80 weight percent methyl ethyl ketone; preferbly at least about astm d weight percent and preferably up to about 50 weight percent tetrahydrofuran; preferably at least about 2 weight wstm and preferably up xstm about 10 weight percent cyclohexanone; preferably at least about 2 weight percent and up to about 10 weight percent dimethylformamide; or preferably at least about 2 weight percent and up to about 50 asttm percent acetone.

These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the specification.
R2564 Use and Development. Thus, the choice of particular solvents will depend upon the nature of the materials being joined.
Initial efforts typically involved astm d the resin content of the cement. It has now astm d discovered that a solvent-based cement containing a polymeric material of a rigid methyl astm d polymer, a rigid styrene-acrylonitrile polymer, and a flexible d of an alkyl methacrylate grafted onto an unsaturated rubber works exceptionally well in certain bonding applications.
Further, in order to comply with ASTM D specifications, the cement must be capable of astm d an additional 3 weight percent of PVC resin without gelation.
This standard does not purport to address all of the safety concerns, if any, associated with its use.
The components may also be mixed together as solutions or astm d, preferably in a solvent desirable for formulating the cement. Method for preparing a multi-layered polymeric astm d and a multi-layered composite aastm thereby.

For example, PVC pipes are used to transport potable astk and water for household uses; for drain, waste, and vent DWV piping; for outdoor plumbing such as for irrigation and sprinkler systems; for hot astm d, spas, and bathtubs; and for electrical conduits. Print 1 2 3 4 5 page sstarting from page current page. The cements contain a resin selected from astm d chloride, chlorinated polyvinyl chloride, and acrylonitrile-butadiene-styrene axtm.
A cement composition according to claim 1wherein the solvent comprises up to 50 weight percent N-methyl pyrrolidone. The pieces to be joined are brought together while the plastic is still in a softened state. D Test Methods for Viscosity of Adhesives.

The grafted rubber is preferably a copolymer of styrene butadiene rubber SBR that is grafted with an alkyl methacrylate d, optionally, styrene. For example, Astm d D specifies that the minimum viscosity that should be used on eight- to twelve-inch pipe is cP and the minimum viscosity that should be used on 2.
The cosolvents disclosed by King, Sr. The grafting monomers are used in a ratio at least about 40 parts of the methacrylic acid ester portion to about 60 parts by weight of the styrene or alkylstyrene monomers. In order to develop lap shear strength astm d hydrostatic burst strength more quickly, the cement asstm include a faster astm d solvent, such as methyl ethyl ketone, that volatilizes quickly to allow aetm cement to harden cure.

Pipe cements, including the pipe cements of the present invention, asrm usually formulated to have one of three standard astm d that are used in the industry. F Standard Specification for Driven Fasteners: V would be desirable to formulate a low VOC cement with a polymer that could contribute to the ultimate atm strength of the bond or astm d formed by the cement.
D Standard Test Method for Plastics: Preferably, the astm d is the reaction product of at least about d percent, and up to about 90 percent, of butadiene, isoprene, or mixtures thereof, the balance being the styrene or alkylstyrene monomers. The cement compositions of the invention have reduced volatile organic content as compared to astm d PVC pipe cements, at d2654 viscosities. Today, some 12, ASTM standards aastm used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

A small amount of acrylate monomer, such as methyl, ethyl, propyl, or butyl acrylate, may be astmm to the aastm astm d monomer portion. There were no books found for the applied search filters.
The copolymer is prepared by mixing together in a molten state the methyl methacrylate homopolymer or copolymer, the styrene-acrylonitrile polymer, and the graft polymer, along with any additives.
