What is 2K RTV Silicone Gasket Maker?

‘2K’ in this context stands for ‘Two-Component.’ Therefore, 2K RTV Silicone Gasket Maker is a two-component room-temperature vulcanizing (RTV) silicone gasket maker. This means that the adhesive consists of two separate components that react chemically and harden when mixed and applied.

Strong Points

Compared to a one-component RTV silicone gasket maker, the curing process of a 2K RTV silicone Gasket Maker is more controllable, faster, and does not depend on environmental conditions such as humidity and temperature. This makes 2K RTV silicone gasket maker an ideal choice for many applications, particularly where fast curing and high-performance bonding are required.

Weak Points

However, using 2K RTV silicone gasket maker requires more considerations, such as ensuring that the two components are mixed in the correct ratio and that the mixture is used within a certain time after mixing (known as the pot life or working life). Also, since 2K RTV silicone gasket makers typically cure very quickly, more precise bonding operations are needed to avoid mistakes or uneven bonding.


On the other hand, the use of a one-component RTV silicone gasket maker is simpler, requiring only the application of the adhesive and then waiting for it to cure under ambient conditions. However, its curing process is generally slower and is more influenced by environmental humidity and temperature.
