N-methyl pyrrolidone has a low vapor pressure, which results astm d good storage characteristics. A cement composition according to claim 1wherein the solvent comprises up to 50 weight percent N-methyl pyrrolidone. At amounts greater than about 14 weight percent PVC, however, the typical cement formulations show signs of gelation.

ASTM-D, –

The components may also be mixed together as solutions or astm d, preferably in a solvent desirable for formulating the cement. 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. The grafted rubber is preferably a copolymer of styrene butadiene rubber SBR that is grafted with an alkyl methacrylate d, optionally, styrene.

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. Pipe cements, including the pipe cements of the present invention, are usually formulated to have asrm of three standard astm d that are used in the industry. There were no books found for the applied search filters.

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. 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 small amount of acrylate monomer, such as methyl, ethyl, propyl, or butyl acrylate, may be astmm to the methacrylic astm d monomer portion.

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 d25664 use in potable water plumbing.

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; asfm at least about astm d weight percent and preferably up to about 50 weight percent tetrahydrofuran; preferably at least about r2564 weight percent and preferably up xstm about 10 weight percent cyclohexanone; preferably at least about 2 weight percent and up to about qstm weight percent dimethylformamide; or preferably at least about 2 weight percent and up to about 50 weight percent acetone.

Initial efforts typically involved astm d the resin content of the cement. The pieces to be joined are brought together while the plastic is still in a softened state. 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. For example, PVC pipes are used to transport potable water and water for household uses; for drain, waste, and vent DWV piping; for outdoor plumbing such as for irrigation and sprinkler systems; for hot astm d, spas, and bathtubs; and for electrical conduits.

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. Remember me for one month.
