Product
Description
This
product is a heat stable, non-carbonizing release agent. The heat-cured
film of MR225 does not usually transfer nor migrate, so that painting,
finishing, bonding or other secondary processing steps may be accomplished
on molded parts without further treatment. MR225 is thermally stable
up to 900° F. Epoxies, phenolics, polyimides, polybismaleimides
and polyester parts release freely from the mold on cures up to
900° F. Application instructions should be followed closely
to obtain these results. MR225 is designed for metal or non-metal
tools. It is a clear liquid but may be colored on special order.

Application
MR225
may be applied over existing release agents by spray, brush or wipe-on.
It works best when applied on a clean mold. Two coats applied in
opposite directions give optimum results. Allow 15 minutes for solvent
release before applying the second coat. When applying the second
coat with a rag, make sure the rag is thoroughly saturated with
MR225. Any dry spot on the rag could remove the first coat. After
the second coat is applied, bake at 250° F. (120° C) for
60 minutes. New tools may require more than two coats. New tools
should be heated to 250° F. before applying MR225. This will
open the pores and allow the release agent to go into pores.
Removal
Of Old Release Agent
Scrubbing with metal pads saturated with detergent is the best method
for old release agent removal. Follow with a solvent wipe.
Resin
Removal
Sanding is recommended for resin removal.
Transfer
Should MR225 transfer, use the metal pads, detergent and solvent
wipe. Transfer usually indicates the MR225 was too heavily applied.
