Customer Questions & Answers

Question:
What is Permatex 81878 Ultra Copper Maximum Temperature RTV Silicone Gasket Maker used for?
Answer: Permatex 81878 Ultra Copper is a high-performance RTV silicone gasket maker designed for high-temperature applications. It creates a dependable seal that can withstand extreme temperatures, up to 700°F (371°C). It's ideal for automotive repairs, especially for sealing valve covers, oil pans, and exhaust manifolds, making it perfect for DIY enthusiasts and professional mechanics alike. -
Question:
How does the Ultra Copper RTV Silicone Gasket Maker differ from other gasket makers?
Answer: The Ultra Copper variant stands out due to its exceptional resistance to high temperatures and its ability to form a strong, durable seal in extreme conditions. Unlike standard silicone gasket makers, it is engineered to withstand the heat generated in engine applications, ensuring long-lasting integrity even under intense stress. This makes it suitable for critical automotive components where reliability is essential. -
Question:
Can I use Permatex Ultra Copper on all surfaces?
Answer: While Permatex Ultra Copper is versatile, it's essential to check compatibility based on the materials being sealed. It adheres well to metal, rubber, and some plastics, making it ideal for most automotive applications. However, it is not recommended for use in applications that may be submerged in fluids for extended periods, as this could compromise the seal. Always refer to the product's guidelines for best use. -
Question:
How long does it take for the Permatex Ultra Copper RTV to cure?
Answer: Permatex Ultra Copper typically takes about 24 hours to fully cure at room temperature. However, it sets quickly enough for assembly after a short period, usually around a few hours, depending on conditions like temperature and humidity. For optimal performance, allow the gasket maker to cure undisturbed before subjecting the joint to service conditions. -
Question:
Is the Ultra Copper RTV silicone safe to use on engine components?
Answer: Yes, the Ultra Copper RTV is specially formulated for use on engine components. It is non-toxic once cured and does not chemically react with automotive fluids, making it a safe choice for sealing gaskets in engines, transmission cases, and oil pans. Always ensure surfaces are clean before application for best results. -
Question:
What is the shelf life of Permatex Ultra Copper Gasket Maker?
Answer: Permatex Ultra Copper Gasket Maker has a shelf life of about 12 months when stored in a cool, dry place, with the cap tightly secured. Using the product within this time frame ensures optimal performance, as its adhesive properties can diminish over time if exposed to air. Check the expiration date on the packaging before use. -
Question:
Can I use Permatex Ultra Copper on my motorcycle?
Answer: Yes, Permatex Ultra Copper is suitable for motorcycles as it withstands high temperatures and forms strong, reliable seals. Whether you're sealing gaskets in your engine or working on exhaust connections, this RTV silicone can be an effective solution. Just ensure that you apply the product correctly and allow adequate curing time. -
Question:
What is the recommended application method for the Ultra Copper RTV?
Answer: To apply Permatex Ultra Copper, start by cleaning the surfaces thoroughly to remove any old gasket material or debris. Apply a continuous bead of the gasket maker directly to one surface, making sure it's even. Press the two surfaces together, ensuring proper alignment, and allow it to cure as per the guidelines. This method ensures a strong, leak-proof seal. -
Question:
Can I paint over Permatex Ultra Copper once it’s cured?
Answer: Yes, you can paint over Permatex Ultra Copper once it has fully cured. However, it is advisable to use a compatible type of paint to ensure adhesion. Allowing the product to cure completely will provide a strong bond and ensure that the paint adheres properly, making it a great option for restoration projects or when a polished look is desired. -
Question:
Where can I buy Permatex 81878 Ultra Copper Maximum Temperature RTV Silicone Gasket Maker in Australia?
Answer: You can purchase Permatex 81878 Ultra Copper Maximum Temperature RTV Silicone Gasket Maker at Ubuy. They offer a reliable shopping experience with a variety of options for this product, ensuring you get exactly what you need for your projects.
