Description
87-95
Plastilease 512B is a water/alcohol solution of polyvinyl alcohol
resins (PVA). It is used to release polyester resins, especially
where wax or silicone contamination of the part is to be avoided.
The film it produces serves as insurance against part hang-up, particularly
for newly fabricated molds. During the break-in period (usually
2 to 3 production cycles) Plastilease 512B provides good release
until the exothermic reaction forces the wax to fill microscopic
mold pores. Plastilease 512B is a deep green color for visibility
against the mold.
87X65
Plastilease 512CL, identical to 512B, is a colorless formula
for use when a clear solution is desired.

Application
Both
87-95 and 87X65 can be applied by spraying or brushing. Spray
application is preferred. It will flow out readily over wax or silicone
without fish-eyeing. Over-spraying or multiple coats are not necessary.
Should
slight laminate hang-up or sticking occur, warm water may be worked
into the interface of the mold and the part. The water will re-dissolve
the PVA film and float the stubborn part free. Plastic, wood and
other porous molds should be dried well and sealed with 96-91 Mold
Sealer 306 before application of the Plastilease product.
