PRODUCT DESCRIPTION 

1. It is a one part neutral curing sealant with excellent flexibility and high movement ability, it is specially designed 

for use in gasket replacement or coating gaskets for high temperature areas. 

2. It is easy to use, cures on exposure to moisture in the air to form a tough, flexible, silicone rubber gasket which can replace 

gaskets for sealing and can also be used as a washer dressing 

3. It shows excellent resistant to aging, weathering and thermal cycling, without hardening, shrinkage or cracking.
 

FEATURES

1. Excellent flexibility and water resistance 

2. Improve the bearing capacity and shock absorption capacity of the bonding area 

3. Resistant to oil and antifreeze 

4. Resistance to weak acid and alkali 

5. Easy to use

 

APPLICATION

1. Commonly used as a field formed gasket/sealant, it provides superior performance in typical automotive flat seal 

applications. 

2. Typical applications include oil sump, transmission housing, valve chamber cover, timing gear cover and differential 

housing 

3. The product is usually used in applications with a maximum temperature of 260 °C.

 

RESTRICTIONS

APPLICATION TEMPERATURE: +5ºC to +45ºC 

1. Cleanse with a cleaning agent, to keep the substrate surfaces completely clean. 

2. Use the sealant after cleaning agent dries, around 1~2mins later. You can use two different cloth, one for 

cleaning agent, and the other for sealant.
