    Again we see an example of a helper trying to play chemist. The cleaners and cements contain acetone or butanone, cyclohexane, and other non-polar solvents (depending on the brand used). They work by breaking some of the crosslinked PVC chains, thus weakening the overall integrity of the molecule. The solvents in the glues and cleaners are harsh on the lungs and nervous system, so try to work with plenty of ventillation.

    The color is pretty much irrelevent, its just to add to the aesthetics to differentiate one brand from another. I’ve seen white, blue and colorless glues for PVC.

    Your friendly chemist
