1. What is Silicone Gasket Sealant?
In automotive and industrial assembly, leaks and gasket failures can cause costly rework and project delays. RTV Silicone Gasket Sealant provides durable, leak-proof sealing on high-temperature and oily surfaces. It can replace rubber, cork, asbestos, or paper gaskets, helping contractors reduce material waste, save time, and ensure professional installation
2. 5 Common RTV Silicone Sealant Mistakes
(1) Surface contamination causing leaks
Risk: Failing to properly clean the surface before applying RTV silicone sealant can cause poor adhesion, leaks, and costly rework.
Solution: Remove oil, paint, moisture, rust, dust, and other contaminants from the sealing surface. GT101 provides reliable adhesion even on slightly oily surfaces, ensuring a durable, leak-free assembly.
(2) Uneven sealant application
Risk: Applying too much or too little RTV silicone sealant can cause localized leaks, poor adhesion, and even clogging of parts like oil collector mesh. These problems often lead to costly rework, project delays, and wasted materials.
Solution:
- Apply a thin, even layer on the sealing surface.
- Use hand coating, injection, pressure dipping, or vacuum dipping.
- Adjust coating thickness according to gap size and surface flatness: typically 0.2–0.6 mm on both sides; thinner for narrow gaps, thicker for wider gaps.
GT101’s high-viscosity formula maintains reliable sealing even if the coating thickness varies slightly.
(3) Premature assembly or leak testing
After applying RTV silicone sealant, appropriate pressure and time are required to ensure that the glue can fully adhere. If the pressure applied is not enough or the time is insufficient, the sealant may not be completely fixed, resulting in failure of the rtv gasket maker. In the curing process of the glue layer, temperature and time play an important role, and a certain amount of pressure is required. Generally, it needs to be left for 24 hours.
To properly assemble when using RTV gaskets, follow these steps to ensure high-quality assembly:
1. Apply the RTV sealant evenly on the surface
2. Assemble the mating parts and tighten the bolts by hand
3. Let stand for 1 hour, then tighten all fasteners according to the instructions in the vehicle maintenance manual
4. After 24 hours of curing, add the necessary liquid
(4) Failure to clean excess sealant
Gasket silicone sealant is difficult to clean after drying, so during use, the excess sealant edge squeezed out after pressurized curing should be removed in time to avoid affecting the overall effect. Be careful not to peel off the sealant layer during trimming.
(5) Incorrect temperature during construction
When using rtv silicone gasket maker, pay attention to the control of room temperature. Too high or too low temperature will affect the curing speed of the rtv silicone sealant.
Tengyu GT101 Gasket RTV Sealant can replace all kinds of rubber pad, asbestos pad, cork pad and paper pad, can effectively prevent water, oil, gas leakage, with good sealing and leakproof effect.
It is a single component silicone rubber desighed for high-torque applications.
It offers improved adhesion to oily surfaces and is three times more oil resistant than generic silicones. Resists temperatures to 650 ℉( 315℃) and with standshigh vibrations. For assembly as a form-in-place gasket.
