PVC primer & Cement

[fastcannonman]

I have been using PVC primer and cement for years. But i was wondering, is their anything better the PVC cement and primer?

[mopherman]

umm, prime and cement then incase it in concrete?
just stick to primer and cement

[MrCrowley]

It's made specifically for the job, to prime the pipe(clean, soften etc) then to solvent weld the pipe(bond the pipe together by use of a solvent glue).
i just realised my primer and glue expired, its only been a year Still got more then half the jar left in it.

correct me if im wrong but ive always wondered is the cement just primer with PVC in it?

[Modderxtrordanare]

is the cement just primer with PVC in it?

No.

[iPaintball]

Yes, technically it is. Primer and cement both contain the same solvents (MEK. etc) The only real difference between the two is that primer is just solvent, and cement has solvent, and PVC resin.

um, well, lol, i got opposite answers, um we need a third opinion lol

Primer and glue have major differences;

1. Primer usually has the purple die in it.

2. Glue contains dissolved PVC but primer does not.

3. There are big difference in the proportions of the various solvents.

4. Primer is 70~80% Acetone but glue has only a trace.

5. In glue, the Acetone is replaced with methyl ethyl ketone (MEK) and tetrahydrofuran (THF) which are chemically similar to Acetone but have higher boiling points.
