In Ghana, epoxy resin can be purchased at various home improvement stores, specialized chemical suppliers, or through online marketplaces. Stores like Orca Deco and K. Badu Foam and Plastic Products often stock a range of epoxy resins suitable for various projects. Additionally, online marketplaces like Jumia, Tonaton, and Ghana Buy Sell offer the convenience of home delivery, with options available from both local and international sellers. It's advisable to compare prices, check reviews, and confirm product specifications before purchasing to ensure the epoxy resin meets your specific needs. For bulk purchases or specialized types, contacting direct suppliers or manufacturers through their official websites or business directories in Ghana may provide more options and competitive pricing.
Sealing screen print ink is crucial for ensuring the longevity and durability of your printed designs. After screen printing, the ink must be cured properly. This process involves heat application, which chemically binds the ink to the fabric. For most plastisol inks, use a flash cure unit or an oven to apply heat evenly. Ensure the temperature reaches around 320°F (160°C) – high enough to cure the ink but not damage the garment. Water-based inks require a different approach; they need to be heated to 290°F (145°C) to evaporate the water content fully. To test if the ink is properly cured, perform a peel test by attempting to lift the ink off the fabric after cooling. If it doesn't come off, the curing process was successful. For extra protection, especially on non-fabric surfaces, consider using a clear coat sealer that's compatible with the type of ink used. This additional layer can enhance resistance against wear and tear.
PVC, being a non-porous plastic, cannot be stained in the traditional sense since stains are meant to penetrate the surface. For coloring or "staining" PVC white, the best approach is using a paint specifically designed for plastics. Begin by cleaning the PVC thoroughly to remove any dirt or oils that could prevent adhesion. After drying, apply a primer made for plastic surfaces to ensure a good base for the paint. Once the primer has dried completely, apply a high-quality spray paint designed for plastic in several thin coats, allowing for proper drying time between coats. It's crucial to use paint that bonds to plastic to achieve a durable finish. This method effectively changes the color of PVC to white, resembling the look of a traditional stain but through surface coating.
