SONDERHOFF FERMASIL Two-component, room temperature cross-linking silicone systems for sealing and potting

The tailor-made chemistry for growing requirements. SONDERHOFF FERMASIL is the two-component silicone system for the manufacturing of soft elastic silicone elastomers and silicone foam sealings, which are applied directly onto the part by using FIP(F)G (Formed-In-Place (Foam) Gasket) technology. SONDERHOFF FERMASIL is processed using low pressure mixing and dosing machines for two components. Suited for silicone sealants are dynamic or static mixing systems. Henkel recommends dynamic mixing systems for increased ease of material processing. The systems consist of an A-component and a cross-linking...

SONDERHOFF FERMASIL Two-component, room temperature cross-linking silicone systems 10 good reasons for SONDERHOFF FERMASIL: 1. … can be used at a constant temperature up to +180 °C, for special types up to +250 °C and temporary up to +350 °C. 2. … keeps the greatest possible flexibility even down to -60 °C. 3. … is closed-cell and therefore nearly do not absorb water. 4. … is highly resistant to many chemicals. 5. … is hydrolysis stable and therefore suitable for use in tropical or damp environments. 6. … is tack-free in 2 – 60 minutes, depending on the thermal conditions. A furnace can significantly...

SONDERHOFF FERMASIL The technology SONDERHOFF FERMASIL – The components SONDERHOFF FERMASIL – The reaction process SONDERHOFF FERMASIL sealing foams consist of a liquid to pasty A-component and a cross-linking B-component. The chemical reaction of SONDERHOFF FERMASIL sealing foams is initiated by mixing the A- and B-components. The applied compound foams up to a uniform gasket under room temperature conditions. Foaming-up time Tack-free time Assembly time SONDERHOFF FERMASIL – The foaming process > Pot life: The time span from the mixing of the A- and B-components to the beginning of the foaming...
