Tecno-Sil 621 Silicone Sealant (Sanitary)

Tecno-Sil 621 is a high modulus one-component, easy to tool, silicone sealant which when exposed to atmospheric humidity cures rapidly to form a permanently flexible and extremely durable sanitary and weather-tight seal. The cured sealant will accommodate joint movement of 25 % throughout a wide temperature range.
Tecno-Sil 621 is a high modulus sealant and should be selected for use on applications where joint loads are high and where relative movement between substrates is to be minimised and sanitary applications.
