PRODUCT DESCRIPTION

1. This is a superior one-part, neutral curing sealant offering remarkable flexibility and exceptional movement capability, crafted uniquely

for optimal performance in gasket replacement and coating, especially in high-temperature areas.

2. Its user-friendly design allows for easy application, curing upon air moisture exposure to form a durable, flexible, silicone rubber gasket.

3. Boasting outstanding resistance to aging, weathering, and thermal cycling, it maintains its integrity without hardening, shrinkage, or cracking.

FEATURES

1. Exceptional high-temperature resistance

2. Non-corrosive formulation

3. Superior resistance to automotive oil

4. Enhances load bearing capacity and shock absorption in bonded areas

5. Effortlessly easy to apply

 

APPLICATION

1. Ideally suited for oil pans, transmission housings, valve chamber covers, timing gear covers, and differential housings.

2. Versatile temperature range usability from -54°C to 260°C.

 

RESTRICTIONS

1. Avoid application on substrates with surface temperatures exceeding +50ºC or below 5ºC; not suitable for surfaces with direct food contact.

 

2. Not designed for sealing high pressure; unsuitable for seals in direct gasoline contact; not for cylinder head gasket replacement.

 

3. Not recommended for use in structural glazing applications.
