Revolutionary one part filler that is solvent free!!!!

We have developed a non-hazardous powder-coating filler. This is a revolutionary product that will allow powder-coating applicators to repair parts with minor damage, pits, voids and other imperfections.

Thermobond-3 is easy to use. Remove lid and heat the 1 lb. jar of product for 15-20 seconds and stir until it is a soft consistency. Then, spread it on and bake it into place by following the curing instructions carefully.

SURFACE PREPARATION: The metal surface must be clean, dry and free of wax, oil, grease and any other contaminates. Lightly rough up the surface by sanding, wire wheel, or abrasive blast to enhance adhesion properties and promote mechanical bonding. Standard in-line pretreatment systems such as iron or zinc phosphate are preferred. Thermobond-3 can only be applied to clean, dry metal. Thermobond-3 should never be applied over a damp, wet or contaminated surface.

APPLICATION: Using a clean-gloved hand, firmly press a thin layer over the surface area to secure a good bond to the entire surface. Now, apply the desired thickness (not more than 1/4 inch recommended). The part must then be heat cured. Another 1/4 of an inch can be applied for deeper dents, then cured. This process can be repeated as many times as needed in 1/4 of an inch at a time. Please see "Applying Thermobond-3" page.

The filler will not air dry, it must be cured in an oven. Please see "Curing Instructions" page.

Thermobond-3 will not properly cure with a heat gun. We recommend powder coating ovens for accurate thorough heating all the way through.

Here are examples of just a few of the industries that currently use this product: Motorcycle Builders, Car Restoration, Window and Door Manufacturers, Cast Iron Restoration, Outdoor Furniture, Metal Gates and many others. Thermobond-3 has proven to be a very effective way to bridge the gaps and voids when powder coating is to be applied as the final finish.

We at Powershield Doors would like to congratulate you at Dura-Chem on the outstanding product you supply us with your Thermobond-3 filler. As you are aware we have been using your product with great success for a number of years now. After extensive market research, we found it to be the only filler we could use under high temperatures in our dry powder painting process.

Definitely a great innovation.

Well done,

Mark Hampton
