Hydroseal® Canada 90 Callibre Primer
is a low VOC emission, non-bodied, fast acting primer. The strong, aggressive action of 90
Callibre Primer rapidly softens and dissolves the joining surfaces of PVC and CPVC pipe and
fittings. The benefit of this priming action is especially noticeable on parts being joined
together in cold weather. Available in clear and purple; the latter allows easy identification
when used on the joining surfaces.
Hydroseal® Canada 90 Callibre Primer, when used in conjunction with appropriate
Hydroseal® Canada solvent cements, will make consistently strong, well fused joints. It is
essential that the joining surfaces of pipe and fittings be softened and remains softened
prior to assembly. The main function of the primer is to expedite the penetration and
softening of the surfaces. Its rate of penetration into the joining surfaces is more rapid than
that of solvent cement alone. 90 Callibre Primer is suitable for use with all types, classes
and schedules of PVC and CPVC pipe and fittings.
