Weicon Plastic Metals offer a versatile and high-performance solution for a variety of industrial repair and maintenance needs. Whether you’re rebuilding damaged parts, providing surface protection, or addressing corrosion issues, these epoxy compounds deliver reliable and durable results. This guide will help you apply Weicon Plastic Metals effectively, ensuring a strong bond and a high-quality finish.
1. Prepare the Surface
a. Clean Thoroughly
Begin by cleaning the surface where you’ll apply the Plastic Metal. We recommend using the Weicon Surface Cleaner to remove all dirt, oil, grease, and contaminants. For best results, use a wire brush or abrasive pad to clean rust or old coatings from the surface.
b. Remove Loose Material
Scrape away any loose or flaking material. This step is crucial for ensuring good adhesion between the Plastic Metal and the surface.
c. Roughen the Surface
Lightly sand or roughen the surface using sandpaper or a sanding block. This creates a rough texture that helps the Plastic Metal adhere better. Ensure that the surface is clean and dry before proceeding.
Swift Supplies Tip: If you encounter rust in your application, we recommend using Weicon Rust Converter. This effective product not only stops rust in its tracks but also prepares the surface for painting or coating. It works by chemically converting rust into a stable, protective layer, preventing further corrosion.
2. Choose and Prepare the Plastic Metal
a. Select the Right Product
Weicon offers a range of Plastic Metal products tailored for different applications:
-
Liquid Epoxy Resins: Ideal for coating and sealing.
-
Putty-Like Compounds: Suitable for filling gaps and repairing damaged parts.
-
Specialty Products: Includes options for wear protection and corrosion resistance.
b. Read the Instructions
Check the product’s label or technical data sheet for specific instructions regarding mixing ratios, application techniques, and curing times.
c. Mix the Components
Most Weicon Plastic Metals Epoxy Kits come in two parts: a base and a hardener. Measure the correct amounts of each component as per the product instructions. Mix thoroughly in the main container until the mixture is uniform in color and consistency. For putty-like compounds, knead the material until it is fully blended.
Swift Supplies Tip - We recommend continuing to mix the epoxy even after it appears to be fully blended, Also try to prevent adding air bubbles into the mixture.
3. Apply the Plastic Metal
a. Application Method
Use a spatula, putty knife, or applicator tool to apply the mixed Plastic Metal to the prepared surface. For liquid resins, you might use a brush or roller for even application.
b. Fill and Repair
For filling cracks, gaps, or holes, press the Plastic Metal into the damaged areas, ensuring a good fill. For repairs, cover the damaged part completely and smooth it out to match the surrounding surface.
c. Shape and Smooth
Shape and smooth the applied material using the tool. For putty-like products, you may need to shape it to fit contours or gaps precisely. For liquid resins, ensure an even coat with no bubbles or streaks.
Swift Supplies Tip - When working with our Plastic Metals, it's crucial to take note of the pot life, which refers to the period during which the mixed product remains usable before it begins to set or cure.
4. Allow to Cure
a. Curing Time
Follow the manufacturer’s instructions for curing times. Weicon Plastic Metals typically have specific curing periods, and it’s crucial not to disturb the material until it has fully set.
b. Environmental Conditions
Ensure the application area is within the recommended temperature and humidity ranges. This information is provided in the product instructions and affects the curing process.
5. Finish and Inspect
a. Sanding and Smoothing
Once fully cured, sand the surface if necessary to achieve a smooth finish. Use fine-grit sandpaper to blend the repair with the surrounding area.
b. Painting or Coating
If required, you can paint over the cured Plastic Metal to match the surrounding surface. Ensure that the paint or coating is compatible with the epoxy resin used.
c. Final Inspection
Inspect the repaired area for any imperfections. Check that the Plastic Metal has adhered properly and that the repair is robust and durable.
6. Clean Up
a. Clean Tools
Immediately clean any tools or applicators used with an appropriate solvent or cleaner before the Plastic Metal sets. Once cured, it can be challenging to remove.
b. Store Unused Product
Seal any leftover Plastic Metal components in their original containers. Store them in a cool, dry place according to the manufacturer’s recommendations to extend shelf life.
