APW40 Apiezon W40 Wax, Size=250 g. can


Wax W40 is relatively soft; softening at about 40'C.

Wax W would be chosen for sealing most joints; a softer grade is used where the lower softening point makes application easier or where the softer wax is desirable because of probable vibration of the joint.
