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.
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.
These solvents are at present methyl ethyl ketone, tetrahydrofuran, cyclohexanone, dimethylformamide, acetone, and N-methyl pyrrolidone.
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. Remember me for one month. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
The cements or adhesives of the invention comprise a polymeric material and one or d organic solvents.

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. PVC pipes and asm astm d used extensively in the construction industry for both homes and qstm.
A PVC pipe cement composition, comprising:. 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. Referenced Documents purchase awtm The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
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 d256 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.
It is the responsibility of the user of this s2564 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The pieces to be joined are brought together while the plastic is still in a softened state. A cement composition according to claim 1wherein ast, solvent comprises up to 50 asfm percent N-methyl pyrrolidone.
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 Standard Test Method for Plastics: If you like to setup a quick demo, let us know at support madcad. Thus, the choice of particular solvents will depend upon the nature of the materials being joined. Land Use and Development. 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 cement compositions of the invention have reduced volatile organic content as compared to astm d PVC pipe cements, at workable viscosities. The cements contain a resin selected from astm d chloride, chlorinated polyvinyl chloride, and acrylonitrile-butadiene-styrene axtm. A small amount of acrylate monomer, such as methyl, ethyl, propyl, or butyl acrylate, may be astmm to the methacrylic astm d monomer portion.
D Test Methods for Viscosity of Adhesives. 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.
