Alvin Products’ Hi-Temp Lab-metal is a single-component metal putty that can be applied directly from the can using a putty knife and provides adhesion to virtually any cast or machined metal surface. Once heat hardened, the metal filler can be machined, ground, drilled and sanded to a smooth finish which then can be powder coated and painted. The filler can withstand temperatures as high as 1,000°F.
Suitable for smoothing welds and filling cracks, dents or voids, the filler will not shrink, air dries within 24 hours and is weather-resistant, the company says. Typical applications include mold refinishing and repairing core boxes, wood and coal burning stoves, industrial ovens, exhaust systems, engines, radiators, and other parts used at high temperatures.blog comments powered by Disqus
