SoudaFlex FC40 polyurethane sealant gray 600 ml Soudal

SoudaFlex FC40 gray 600ml is a polyurethane-based, one-component, high-performance sealant-adhesive designed for both sealing and strong flexible bonding applications in the construction sector. The product has a moisture-curing system and shows high resistance to structural movements, vibrations and temperature changes, maintaining its permanent elasticity after application. Forms a film (skin) on the surface in about 25 minutes and provides optimal working balance with a curing rate of about 3 mm in 24 hours. With a hardness of 40 ±5 Shore A and an elongation of up to 700%, it prevents seam cracking and provides long-term durability. It stands out for its high adhesion to concrete, metal, aluminum, polyester and other building materials, and at the same time it has high resistance to UV rays, chemicals and various weather conditions. The product operates stably in the temperature range from -30°C to +90°C and is an ideal choice for expansion joints with a deformation tolerance of ±20%. It is widely used for facade work, contraction seams in concrete floors, gluing of roof elements and flexible joints in vibrating constructions. The 600ml `sausage` packaging format allows for more efficient and economical use in large volume jobs and provides a reliable and durable solution for craftsmen, contractors as well as large construction projects.
