Dynatex DynaCopper RTV Silicone Gasket Maker 85g Tube - High Temp Copper Sealant up to 700°F

Dynatex DynaCopper is a single-component RTV silicone gasket maker that's sensor-safe, non-corrosive, and resists oil, water, and coolant. Its flexibility and 700°F intermittent temperature resistance make it perfect for mechanics sealing late-model engines.

  • Forms flexible, high-temp seals up to 700°F intermittently for reliable engine performance
  • Sensor-safe and non-corrosive formula protects electronics and components
  • Resists oil, water, and coolant to prevent leaks in demanding conditions
  • Low odor and low volatility for easier, cleaner application
  • Outperforms traditional copper sprays for superior gasket sealing

Exceptional high-temperature resistance for extreme engine environments. Highly flexible to handle vibration and thermal expansion. Broad chemical resistance enhances longevity.

Temperature rating is intermittent, not continuous exposure. Small 85g tube may require multiple for large jobs. Requires clean, dry surfaces for optimal adhesion.

Welcome to the premier destination for Dynatex Sealing Compounds, where industrial professionals find top-tier solutions for demanding sealing challenges. Featuring products like the Dynatex 143346 DynaCopper RTV Silicone Copper Gasket Maker, this category delivers exceptional high-temperature performance, ensuring leak-proof seals in the harshest environments. Whether you're tackling automotive repairs, heavy machinery maintenance, or exhaust system assemblies, Dynatex stands out for its proven reliability and engineering excellence.

Why Choose Dynatex Sealing Compounds?

Dynatex has built a stellar reputation in the industrial adhesives and sealants market for over decades, specializing in formulations that excel under extreme conditions. Their sealing compounds, particularly the copper-infused RTV silicones, offer unmatched heat resistance, up to 700°F intermittent and 500°F continuous, making them indispensable for high-stress applications. What sets Dynatex apart is the integration of copper flakes, which enhance thermal conductivity and provide metal-like durability without the rigidity of traditional gaskets.

As part of our extensive Industrial Sealants collection, Dynatex products are designed for professionals who demand precision and longevity. Unlike generic sealants, Dynatex compounds cure flexibly to absorb vibration and thermal expansion, preventing cracks and leaks over time.

Key Features of Dynatex Sealing Compounds

When shopping for sealing compounds, focus on attributes that match your application's rigors. Here's what to prioritize in Dynatex offerings:

  • High-Temperature Resistance: Handles extreme heat from engines, manifolds, and exhausts without breaking down.
  • Copper Reinforcement: Improves heat transfer and sealing strength, mimicking pre-formed copper gaskets.
  • RTV Silicone Base: Room-temperature vulcanizing for easy application and sensor-safe formulation to avoid damaging electronics.
  • Flexibility and Durability: Remains pliable post-cure, resisting oil, coolant, and weathering.
  • Easy Application: Available in convenient 85g tubes for precise dispensing without mess.

These features make Dynatex ideal for buyers seeking value through superior performance and reduced rework.

Common Use Cases for Dynatex Products

Dynatex Sealing Compounds shine in scenarios requiring robust, heat-resistant barriers. In automotive workshops, the DynaCopper is a go-to for valve covers, oil pans, water pumps, and thermostat housings. Industrial mechanics use it for compressor housings, turbochargers, and heavy equipment joints where failure isn't an option.

For broader options within our Sealing Compounds category, Dynatex complements alternatives like those from other trusted brands. If you're comparing for specific needs, check out Permatex Sealing Compounds for more general-purpose options or RectorSeal Sealing Compounds for piping-focused seals.
