Product Description

Chemlease® PMR-90 EZ is a rapid-curing, semi-permanent mold release agent built to solve a specific problem: getting clean, multiple releases with minimal transfer on parts that are inherently difficult to release. As the highest-slip version of the Chemlease® PMR family, it's aimed primarily at closed molding of abrasive or low-draft parts — geometries where a standard-slip release agent tends to struggle, since there's little to no draft angle helping the part separate from the tool. It's HAPs-free (as a formula constituent, with only trace manufacturing quantities below 0.1%), offers high thermal stability, and applies easily as a wipe-on film, cutting labor time compared to conventional wax-and-PVA systems.

Benefits

● HAPs free*

● High thermal stability

● Easy to apply

● Multiple releases between applications

● Reduces labor time and cost

*HAPs are not formula constituents of this product. Standard manufacturing processes may result in trace quantities (<0.1%) of HAPs. Chemlease® solvent carriers contain no Class I or II registered ozone-depleting substances.

Mold Preparation

1.Clean mold surface to remove all traces of waxes, release agents, and sealers

2.Clean the mold with Chemlease® Mold Cleaner

3.Apply the appropriate Chemlease® Sealer to new or porous molds (contact a sales rep or distributor for the correct grade)

How It's Used (Base Coats)

The mold surface must be thoroughly cleaned, dry, and free of contaminants. A clean cotton cloth is saturated (not dripping) and wiped on as a smooth, continuous film over no more than a few square feet at a time. As the film begins to evaporate at the edge, the surface is wiped with a second clean dry cotton cloth in a circular motion from the outside working inward, until dry and clear. This is repeated until the entire mold is covered, applying 4–5 total coats with 15 minutes between each complete coat, followed by a 30-minute full cure before production.

If the release agent is left on too long before wiping, smearing or streaking can occur — this is corrected by rubbing the affected area with the same release agent and removing the excess sooner than before. Touch-up coats are reapplied as required, using the same cure schedule as the final base coat.
