Gaskets play a vital role in engines, stopping dust and dirt, fluids, gases, and electrostatic discharges. Pratley, a leader in high-performance adhesives, offers valuable tips for utilising its RTV Silicone Gasket Maker effectively.
“Incorrect gasket application can ruin an otherwise perfect engine build or reassembly,” notes Mark Bell, National Sales and Marketing Manager for Adhesives at Pratley. Below are some essential ‘tips of the trade’ for successful gasket sealing:
- Choose the Correct Sealant: The correct sealant can make all the difference to achieve a 100% reliable gasket. Do not compromise on quality as using inferior and unreliable products can cost you a lot in the long run. Pratley’s RTV Silicone Gasket Maker, a grey tough and elastic silicone rubber, provides superior sealing performance. It offers exceptional durability with a temperature tolerance of -50°C to +300°C for short periods and is non-corrosive. Moreover, it is chemically resistant to various substances, including petrol and diesel for short periods, paraffin, water, oil, and anti-freeze. It is also sensor-safe, making it ideal for use with electrical components.
- Prepare the Surfaces: Proper preparation of the surfaces is crucial for a successful gasket application. Ensure both surfaces where the gasket will be placed are thoroughly cleaned and free from any remnants of the old gasket, glue, or adhesive. Neglecting this step may compromise the efficiency of the seal. Pratley Safety Cleaner is the ideal solution to ensure a clean and well-prepared surface.
- Apply the Right Quantity: Using the correct quantity of sealant is vital. Avoid extremes: Using too much sealant can clog other engine areas, while using too little may result in an inefficient seal. Apply Pratley RTV Silicone Grey Gasket Maker in a single continuous bead to one of the sealing surfaces, ensuring there are no air gaps. It is advisable to encircle all bolt holes as well. Once the surfaces are assembled, tighten the bolts promptly.
- Curing Time: Pratley RTV Silicone Gasket Maker begins to cure within 40 minutes and achieves a full cure after 24 hours. Allow ample time for the sealant to cure completely before subjecting the engine to heavy usage.
By following these tips, you can ensure the reliable and cost-effective sealing of gaskets in your DIY or professional automotive repairs. RTV Silicone Gasket Maker forms part of Pratley’s comprehensive range of high-performance adhesives that are ideal for all kinds of automotive repair applications.
