Area of applications

 Satex PU is suitable f or the sealing of expansion and connection joints which should be resistant to a wide temperature range and subject to major movements such as building partition joints, joints of elements for site assembly, structural steelwork, reinforced concrete structures. It is also suitable for expansion joints of tiled surfaces and cladding panels and for joints in machine, aircraft, automobile, railway and ship construction. For concrete, natural and artificial stone, fibre cement, aerated, concrete, ceramics, metal and wood.



Satex PU is a sealant based on polyurethane. It has good adhesive strength and elasticity and resistant to aging, weathering and underwater stress, insensitive to industrial atmospheres and elastomeric from °20-C through °70+C. Resistant to detergents and to the temporary influence of mineral acids and alkaline solution in weak concentrations. It has excellent non flowing property for vertical joints.

دستورالعمل کار

Working instructions

Preparation of substrates:

All joint sides must by clean, dry free from old joint sealant, plaster and paint residues, rust, oil, wax, grease, dust and poorly adherent parts. Any soiling will result in a reduced bonding on the joint edges. Effloresence and release agents must be removed by wire brush or sandblasting. Absorbent substrates, such as concrete, plaster, masonry and wood: apply the primer Satex PU VN to saturation. After a drying time of 30 minutes up to 5 hours, Satex PU can be applied into the joints. The solvents of the primer must have evaporated prior to the application of Satex PU. After a drying time in excess of 5 hours, the application of the primer must be repeated. Critical substrates and high stress: the primer Satex PU VN is required.


In order to avoid any soiling, the joint sides must be covered with an adhesive tape prior to the application of the sealant. Remove the adhesive tape prior to the curing of the sealant. Satex PU is applied directly from the cartridge with a manual or a gun. The cartridge must be prepared according to the instructions given on page 2 of this data sheet. After filling the joints, it is advisable to smooth the sealant.
