PVC Glue is a mixture of PVC disolved in solvent and is used to weld two pieces of PVC together.
How to use PVC glue
PVC glue is to be applied liberally to all PVC/CPVC joints, pipes or fittings (by use of a brush) where they are going to be connected together. In most cases, a brush is supplied with the glue. Application of glue should be done immediately after the application of PVC primer. (Most PVC glue manufacturers recommend that the cleaner not be allowed to dry before gluing the joint.) As always, the directions on the can provide the best advice on the process of solvent welding.
Health and Safety
PVC glue is a mixture of methyl ethyl ketone, cyclohexanone, tetrahydrofuran, and acetone. Tetrahydrofuran is a known carcinogen in animals, so PVC glue should be used in a well ventilated area. Gloves can be worn, but care should be taken to avoid spilling primer on them, as acetone penetrates through latex and rubber gloves, where it is absorbed through the skin. In addition, long term exposure of skin to these low-polarity solvents will severely dry your skin out, possibly leading to dermatitis. Swallowing PVC glue may result in death, and chronic inhalation of primer fumes can cause damage to several vital organs including the central nervous system, liver, and kidneys. Symptoms of acute (short term) overexposure include dizziness, headache, nausea, confusion, vomiting, and unconsciousness.
Be sure to read warnings and instructions. For more information the MSDS sheet for Oatey PVC Glue is available .
