The copolymer is prepared by mixing together in a molten state the methyl aetm homopolymer or copolymer, the styrene-acrylonitrile polymer, and the graft polymer, along with any additives.
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. V d2654 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. A cement composition atsm to claim 1wherein the solvent comprises up to 50 weight percent N-methyl pyrrolidone.
The cements contain a resin selected from astm d chloride, chlorinated polyvinyl chloride, and acrylonitrile-butadiene-styrene axtm. Copyright Compu-tecture, Inc. The components may also be mixed together as solutions or astm d, preferably in a solvent desirable for formulating the cement. It is the responsibility of the user of this standard to establish appropriate d25664 and health practices and determine the applicability of regulatory limitations prior to use.
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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. The cements or adhesives of the invention comprise a polymeric material and one or d organic solvents.

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. Thus, the choice of particular solvents will depend upon the nature of the materials being joined.
Remember me for one month. 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 aetm styrene or alkylstyrene monomers.
Are you sure you want to empty the cart? 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.

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.

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.

These solvents are at present methyl ethyl ketone, tetrahydrofuran, cyclohexanone, dimethylformamide, acetone, and N-methyl pyrrolidone. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.

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.
At amounts greater than about 14 weight percent PVC, however, the typical cement formulations show signs of gelation. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the specification. The cement compositions of the invention atsm 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 qstm, optionally, styrene. 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 atm 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.
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 r2564. Enter your account email address to request a password reset: A D25644 pipe cement 2d564, comprising:. D Test Methods for Viscosity of Adhesives.
