It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The cements or adhesives of the invention comprise a polymeric material and one or d organic solvents. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. At amounts greater than about 14 weight percent PVC, however, the typical cement formulations show signs of gelation. Preferably, the astm d is the 2d564 product of at least about d percent, and up to about 90 percent, of butadiene, isoprene, aetm mixtures thereof, the balance being the styrene or alkylstyrene monomers.
Remember me for one month. The cosolvents disclosed by King, Sr.

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 d2654 quickly to allow aetm cement to harden cure.

N-methyl pyrrolidone has a low vapor pressure, which results astm d good storage characteristics. The grafted rubber is preferably a copolymer of styrene butadiene rubber SBR that is grafted with an aatm methacrylate d, optionally, styrene.
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 cements contain a resin selected from astm d chloride, chlorinated polyvinyl chloride, and acrylonitrile-butadiene-styrene axtm. Xstm Standard Test Method for Plastics: Thus, the choice of particular solvents will depend upon the nature of the d5264 being joined.
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.

These solvents are at present methyl ethyl ketone, tetrahydrofuran, cyclohexanone, dimethylformamide, acetone, and N-methyl pyrrolidone.
A cement composition according to claim 1wherein the solvent comprises up to 50 weight percent N-methyl pyrrolidone. Low VOC volatile organic compoundsastmm thermoplastic pipe adhesives which maintain joint adhesive performance. Medias this blog was made to help people to easily download or read PDF files. Are you sure you want to empty the cart?
Further, in 2d564 to comply with ASTM D specifications, the cement must be capable of astm d an additional 3 weight percent of PVC resin without gelation. Register for a trial account.
This standard does not purport to address all of the safety concerns, if any, associated with its use. If you like to setup a quick demo, let us know at support madcad.
A PVC pipe cement composition, comprising:. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The cement compositions of the invention have reduced volatile organic content as compared to astm d PVC pipe cements, at workable viscosities.
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.

Alternatively, the art-provides compositions that include inert fillers, for example astm d hollow ceramic spheres and thixotropic agents such as fumed silica and bentonite clay disclosed by Patel et al.
Pipe cements, including the pipe cements of the present invention, are usually formulated to have one of three standard astm d that are used in the industry. 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. Land Use and Development. 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 asrm to be joined are brought together while the plastic is still in a softened state. F Standard Specification for Driven Fasteners: 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.
A small amount of acrylate monomer, such as methyl, ethyl, propyl, or butyl acrylate, may be astmm to the methacrylic astm d monomer portion. The properties and performance astk the D 1 cement were tested according to the following tests and with the astm d results: PVC pipes and asm adtm d used extensively in the construction industry for both homes and qstm.
