[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 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 2008. ProCreate Putty has been suggested as an alternative.
