Phillyseal R
Description
[ITW Philadelphia Resins, Montgomeryville, PA] A trademark for an Epoxy adhesive that was formerly sold as Pliacré. Phillyseal R (for Rat Seal) was originally prepared as a sealer to prevent rats from entering ships and submarines. The viscous epoxy resin contains bisphenol A diglycidyl ether with a magnesium silicate filler. Mixing with the dark-color, amido-amine hardener in 1:1 proportions forms a grayish workable putty-like material. Phillyseal R cures exothermically in approximately 1-2 hours to form a very hard material that can be sanded, cut, or drilled. It will adhere to Wood, Metal, Plastic, Glass, and Porcelain.
Production of this product was discontinued as of 2007. ProCreate Putty has been suggested as an alternative.

Working Properties
- To repair ceramic losses, the catalyzed putty can be rolled into thin sheets, laid over a protected plastic-covered vase, and allowed to slump over the vase to assume its contours. Once set, the sheet could be trimmed to shape and adhered into the loss. It was then finished with acrylic paint.
- For mountmaking, it was often used an an interference layer. Its shape-forming ability allow intimate contact between uneven section of an object and mount (when covered with a suitable protective layer).
