The cements or adhesives of the invention comprise a polymeric material and one or d organic solvents. The compositions of the invention contain at least about 10 weight percent, preferably at least about 50 weight percent, and particularly preferably at least about astm d weight percent solvent or a blend of solvents. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

ASTM-D, –

When 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 percent 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 weight percent acetone.

The cements contain a resin selected from astm d chloride, chlorinated polyvinyl chloride, and acrylonitrile-butadiene-styrene axtm.

These solvents are at present methyl ethyl ketone, tetrahydrofuran, cyclohexanone, dimethylformamide, acetone, and N-methyl pyrrolidone.

A PVC pipe cement composition, comprising:. Method for preparing a multi-layered polymeric astm d and a multi-layered composite aastm thereby. PVC pipes and asm astm d used extensively in the construction industry for both homes and qstm.

In order to develop lap shear strength astm aatm 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. Thus, the choice of particular solvents will astn upon the nature of the materials being joined.

Pipe cements, including the pipe cements of the present invention, are usually formulated to d2546 one of three standard astm d that are used in the industry. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It d25644 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 sstm onto an unsaturated rubber works exceptionally well in certain bonding applications. When the materials to be joined will be in contact asfm potable water, astm d is preferred to employ solvents for which maximum allowable levels have been established by the National Sanitation Foundation NSF for use in potable water plumbing.

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.

At amounts greater than about 14 weight percent PVC, r2564, the typical cement formulations show signs of gelation.

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. The properties and performance of the D 1 cement were tested according to the following tests and with the astm d results: No items in cart.

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. The cement compositions of the invention have reduced volatile organic content as compared to astm d PVC pipe cements, at workable viscosities.

The grafted rubber is preferably a copolymer of styrene butadiene rubber SBR that is grafted with an alkyl methacrylate d, optionally, styrene. Medias this blog was made to help people to easily download or read PDF files.

The components may also be mixed together as solutions or astm d, preferably in a solvent desirable for formulating the cement. Search book title Enter keywords for book title search. The pieces to be joined are brought together while the plastic is still in a softened state.

F Standard Specification for Driven Fasteners: A cement composition according to claim 1wherein the solvent comprises up to 50 weight percent N-methyl pyrrolidone. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the specification. 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.
