DESCRIPTION

Joint dimensions and shapes in facades are subject to changes due to thermal expansion and contraction of the building units. The corresponding movements must be accommodated by the sealant in order to protect the inner parts of the building against environmental influences. The movements are either due to the size of the single building units (e. g. precast concrete elements) or the thermal expansion coefficient of different building materials and temperature variations. Additionally, structural movements may play a role as well. Sika’s flexible and long lasting sealants are able to absorb these movements and therefore ensure tight and durable joints.


Sikaflex® Precast is based on 1 part, moisture curing polyurethane technology. This new moisture-curing technology and the latest production methods allow the formulation of sealants with best properties.
