Details
Low Modulus It is a neutral-curing silicone sealant with a particularly low modulus of elasticity. It has been proven that its elasticity remains constant at temperatures ranging from –50 °C to +150 °C, which is why it compensates for manufacturing and installation tolerances in curtain wall panels. It adheres perfectly to the substrate, which can be made of any absorbent material. Its high resistance to UV rays and weathering, and its ageing resistance superior to that of any other non-silicone sealant, are the reasons why, even after 20 years of service, the joints show no signs of surface micro-cracks or chalking. Low Modulus It complies with standard EN ISO 11600, class F 25 LM, and is classified as F-EXT/INT-CC according to EN 15651-1 and PW-EXT/INT-CC according to EN 15651-4, i.e. a non-structural sealant for façade elements, walkways and interiors, including in areas with cold climates.
Instructions for use
- The sides of the joint must be clean, free of grease and dry.
- Apply adhesive tape along the sides of the joint.
- Apply Silicone Primer to the sides of the joint.
- Insert the Torggler sealing cord.
- Insert the cartridge or bag into the appropriate mechanical or pneumatic gun and extrude the sealant generously, using nozzles with a diameter proportional to the width of the joint.
- Smooth with a spatula moistened with Smooth within 5 minutes of application, applying firm pressure to eliminate air pockets.
- Remove the adhesive tape immediately after smoothing.
- Cleaning of tools: while the sealant is still plastic, use solvents; once hardened, clean only mechanically.
Storage
Low Modulus It must be stored in a cool, dry place. Under these conditions, it has a shelf life of at least 12 months. Partially used cartridges can be kept for around 3 months if kept tightly sealed.
Warnings
In the case of porous substrates, we recommend applying Low Modulusr first to prevent any staining caused by potential migration of the silicone plasticiser.
r is not suitable for structural bonding. Cross-linked silicone cannot be painted over.
