PC-Fahrenheit™ Putty Epoxy is the choice for temperatures up to 260° C. It is supplied as a premeasured stick that you mix with fingers. Fast curing (60 min). Best for steam heat applications. A toolbox must. Great on copper and iron.

Here are just a few specific uses (there are hundreds of other uses):

Seal cracked steam or hot water radiator
Stop leaking steam fittings
Fill hole in heat exchanger
Attach thermocouple to hot surface
Seal chimney ductwork

How to prepare a surface for bonding with PC-Fahrenheit™
Remove contaminants such as dust, dirt, oil and grime with a solvent such as denatured alcohol (ethanol), acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner. A mild detergent solution in water is also good removing contaminants. Use a clean paper towel or rag for wiping. Remove rust and loose paint with sandpaper or wire brush. Epoxy typically sticks to most paints. If there is a concern of the paint’s adhesion then remove it with sandpaper, wire brush or paint stripper. Smooth, glossy and shiny surfaces should be roughened using sandpaper to increase adhesion. Adhesion to wet or damp surfaces can be improved by wiping with alcohol. Do not use mineral spirits or paint thinner for removing contaminants.

How to clean-up after PC-Fahrenheit™ application
We recommend wearing disposable gloves when mixing and applying epoxy putty. Remove from skin with soap and warm water. Clean up mixed epoxy before it cures with paper towels and solvent. Denatured alcohol (ethanol), acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner are suitable solvents for removing uncured epoxy. Cured epoxy can be physically removed by prying off with a screwdriver or pliers. It can also be removed with paint stripper or remover.
