Scope of use

TERAFLEX PU 50 FC is a high quality one-component, extremely strong and highly elastic polyurethane based adhesive-sealant, which vulcanizes under the influence of the moisture in the air in the shape of permanently elastic mass. It is used for elastic sealing and bonding of pressure-loaded joints in construction industry and for adhering of constructions and metal materials.

It is recommended for use at places subjected to great pressures and structural connections within vibrating constructions. It seals and bonds metals and construction materials, ventilation and air-conditioning air pipes. It is very suitable for bonding panels, peripheral ledges, thresholds under windows and construction thresholds. It is also used for sealing connecting joints in buildings, vacuum systems, air-pressured installations, containers, wagons, silos, aluminum constructions, sewage systems, automobiles, trailers, ships etc.

TERAFLEX PU 50 FC adheres very well to most construction materials and may be used without priming for bonding glass parts, polished surfaces, porcelain, aluminum, steel, stainless steel, plastics, polyester, many types of hard PVC, painted wood, concrete, masonry and others.

It dries fast without causing corrosion and without running down when applying in vertical joints. After drying it can be grinded and painted on. The hardened sealant is resistant to UV rays and chemical influence. Due to its plastic-elastic characteristics, it maintains extensions caused by changing atmospheric conditions (rain, snow, extreme temperatures, salt water).


Indicative consumption

The indicative consumption depends on the depth of the joints. The table shows how many linear meters may be filled with one cartridge (600 ml) depending on the joint’s measures.
