Perfect chemistry for roofing and timber construction

fischer construction chemical solutions for filling, sealing and bonding speed up workflows, increase application reliability and ensure durable, clean results. In addition to PU construction foams, fischer provides adhesive and sealant solutions based on silicone, polyurethane, acrylic or hybrid polymer technologies.

Hybrid adhesives and sealants - reliable all-rounders

The MS polymer products Flex MS, Multi MS, HighTack MS and Crystal MS combine the advantages of silicone and polyurethane. They are suitable for indoor and outdoor use in construction, installation, repair and sealing applications. These products adhere to a wide range of substrates such as wood, metal, concrete, glass, paint and plastic - even on damp surfaces and without the use of primers.

Additional benefits include paintability, low odour, freedom from isocyanates and solvents, bubble-free curing, and high UV and weather resistance. Thanks to their easy and process-safe application, MS polymer products are also suitable for beginners. Their high tensile strength and Shore hardness make them ideal for load-bearing bonding applications.

The highly flexible, mold-resistant construction sealant Flex MS is ideal for facade joints, expansion joints, floor joints and exterior connections. Its permanent elasticity keeps joints flexible over time, reliably compensates for component movement and ensures safety under changing weather and load conditions. As a universal all-rounder, Multi MS is used wherever bonding and sealing are required at the same time - indoors and outdoors, from facade sealing and HVAC systems to connection, movement and sealing joints.

HighTack MS adhesive offers extremely high initial grab, making it ideal for natural stone, mirrors, electrical fixings or exterior bonding and fixing applications. Crystal MS enables crystal-clear, virtually invisible bonding and sealing, for example with glass, wood and natural stone elements.

Reliable roof sealing

For sealing and repair work on roofing membranes and bitumen sheets - even on damp or oily substrates - fischer developed the roof sealing compound Roof BI. Its bituminous formulation is suitable for joints, penetrations and overlaps and impresses with high resistance to UV radiation, moisture and temperature fluctuations.

PU construction foams for installation, insulation and fire protection

PU foams are indispensable in roofing and timber construction, for example for filling, thermal separation, insulation, sealing and bonding. New to the fischer range is PU-P EVO foam with xtagstartz 0.1% isocyanate - enabling low-emission work. It is ideal for typical installation tasks such as filling joints and insulating cavities. The premium quick-assembly and well foam PU Pro offers even greater safety, comfort and efficiency thanks to the new fischer FixAdapter. Precise one-handed operation, an ergonomic trig- ger, optimised valve technology and integrated safety features make application easier.
