FERMASIL silicone systems
Two-component, room-temperature cross-linking silicone systems for sealing, gluing and potting
FERMASIL
Silicone systems for extreme usage conditions
FERMASIL is the 2-component silicone system for the manufacturing of soft elastic silicone elastomers and silicone foam sealings for extreme usage conditions.
Using FIPFG dispensing technology (Formed-In-Place-Foam-Gasket), FERMASIL is applied directly to the part and cures there at room temperature.
Chemical reaction and FERMASIL properties
The FERMASIL silicone foam seal systems consist of a silicone (A-component) and a cross-linking B-component, which are mixed with each other in a redetermined mixing ratio. After mixing the components, most systems react by their own at room temperature and generate a soft elastic silicone foam sealing or permanently elastic silicone elastomers.
FERMASIL is processed using low pressure mixing and dosing machines for two components. Suited for silicone sealants in dynamic or static mixing systems. Henkel recommends dynamic mixing systems for increased ease of material processing.
FERMASIL can be used at a constant temperature from -60 up to +180 °C and for a short time up to +350 °C, while maintaining its softness and flexibility at any time. Due to its closed cell structure, FERMASIL does not absorb water and is suitable for use in tropical or damp environments. It is also highly resistant to other chemicals (e. g. commercial cleaning agents, alcohols, diluted acids and lyes, brake fluids, and cooling agents).
Henkel can draw on the variety of more than 200 application-specific formulations of the FERMASIL product family.
