Silicone acrylate high quality product with excellent water vapor permeability, low water absorption and high durability. Ideal for areas with high humidity and extreme weather conditions.

Acrylan Silicon is a silicon acrylic product for exterior use, which offers excellent water vapour permeability, low water absorption, long life and at the same time durable and elegant decoration. Unlike other products, in addition to excellent resistance to UV-radiation and weathering, enables the moisture that is trapped inside the wall to escape easily in the atmosphere which in combination with the high surface waterproofing prevents problems such as blisters, cracking, peeling and formation of mold on the surface of the building. It applies to all new or old surfaces such as plaster, concrete or surfaces leveled with putty after appropriate preparation. These properties make Acrylan Silicon ideal for areas with high humidity and extreme weather conditions as well as for the restoration of listed buildings, actively contributing to maintaining the longevity of the building.
