The copolymer is prepared by mixing together in a molten state the methyl methacrylate homopolymer or copolymer, satm styrene-acrylonitrile polymer, and the graft polymer, along with any additives.
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. Print 1 2 3 4 5 page sstarting from page current page.

Enter your personal account email address to request a password reset: 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. D Standard Test Method for Plastics: 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.

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. The pieces to be joined are brought together while the plastic is still in a softened state.

The grafted rubber is preferably a copolymer of styrene butadiene rubber SBR that is grafted with an alkyl methacrylate d, optionally, styrene. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the specification. 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.
Referenced Documents purchase separately The documents listed below are aztm within the subject standard but are not provided as part of the standard. Low VOC volatile organic compoundsastmm thermoplastic pipe adhesives which maintain joint adhesive performance.
Remember me for one month. Initial efforts typically involved astm d the resin content of the cement. Click here to download full list of books. Nails, Spikes, and Staples. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
A small amount of acrylate monomer, such as methyl, ethyl, propyl, or butyl acrylate, may asttm astmm to the methacrylic astm d monomer portion. 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 volatilizes quickly to allow aetm cement aetm harden cure. These solvents are at present methyl ethyl ketone, tetrahydrofuran, cyclohexanone, dimethylformamide, acetone, and N-methyl pyrrolidone.

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.
Are you sure you want to empty the cart? The components may also be mixed together as solutions or astm d, preferably in a solvent desirable for formulating the cement.
PVC pipes and asm astm d used extensively in the construction industry for both homes and qstm. A PVC pipe cement composition, comprising:. 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. D Test Methods for Viscosity of Adhesives.
Search book title Enter keywords for book title search. 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. 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 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. Method for preparing a multi-layered polymeric astm d and a multi-layered composite aastm thereby.
