  • Plasti-Bond: Chris’ Corner— Failure of PVC coating on rigid conduit What caused the failure of the protective PVC coating shown in the photograph below?

    It failed because of inferior manufacturing and was delivered to the jobsite already in a failed condition.
    In short — this is an example of premature product failure at its most extreme.
    Technically, this represents a failure of PVC coating to adhere to the steel conduit substrate that … Read more…
