Details
Low Modulus is a neutral-curing silicone sealant with a particularly low elastic modulus. Its elasticity has been proven to remain 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 ultraviolet rays and atmospheric agents and its resistance to ageing, which is superior to any other non-silicone sealant, are the reasons why, even after 20 years of use, the joints show no signs of surface micro-cracks or chalking. Low Modulus complies with 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. non-structural sealant for façade elements and walkways and interiors, even in areas with cold climates.
Instructions for use
- The joint interfaces must be clean, dry and free of grease.
- Apply masking tape along the sides of the joint.
- Apply a coat of Primer Silicon.
- Insert the caulking cord.
- Insert the cartridge in the appropriate gun, open it, screw on the nozzle and cut off the tip to obtain a sufficient opening.
- Apply a generous amount of sealant.
- Tool with a damp spatula within 5 minutes of application, using a light pressure to eliminate any air bubbles.
- Remove the masking tape immediately
Cleaning
Uncured sealant can be removed with solvents; cured sealant must be scraped off.
Storage
Low Modulus must be stored in a dry, cool area. Under these conditions it can be stored for at least 12 months. Once opened, cartridges can be stored for approximately 3 months if tightly closed.
Warnings
In the case of porous substrates, we recommend the preventive use of Silicone Primer to avoid the possible formation of halos due to potential migration of the silicone plasticiser.
Low Modulus is not suitable for structural bonding. Cross-linked silicone cannot be painted over.

Since it has been specifically formulated for the requirements of the building industry, Low Modulus is the most appropriate silicon sealant for sealing expansion joints and connections between concrete, metal, plastic or wood facades, between prefabricated concrete panels, partition walls and upright, between windows and walls, between ceramic wall tiles, between external pipes and pipe connections and walls.
