The Loctite 398489 is a clear mold release agent that comes in a 9.6 oz aerosol can The general purpose, fast evaporating liquid is ideal for use on fiberglass reinforced polyester (FRP) composites, epoxies, polyester resins, vinyl ester resins, thermoplastics, adhesives, and more.
The Frekote 770-NC synthetic mold release I ordered has a 6-month shelf life from the factory. The can I received on 8/25 was set to expire on 8/31 according to the date printed on the bottom of the can. I called and sent a photo of the can bottom and they said it should have been taken off the shelf a month earlier, so they will send me a good can when new stock arrives without sending the out of date can back.
I appreciate the fast delivery and them taking care of the issue, but it means you could be buying product that has only one month of shelf life remaining. Call before you buy and have them confirm the expiration date of their stock and if it is less than works for you, work out delivery from fresh stock or negotiate a discount.
This was my first time using it, and it worked great! I had plenty of work time, and just 24 hours later it was fully cured and ready to go. Excellent product with fast service. Pilots HQ is now my go-to source for epoxy—it’s the best because it’s strong and reliable.
