Alchimica's Hyperseal sealants have been used for the Belgrade National Stadium repair and re-coat project in Serbia.
HYPERSEAL® 25LM is a novel low modulus expansion joint sealant, especially formulated to contain both PU and silylated – PU technology, thus giving rise to a sealant which includes the best of both technologies.
Additionally, the sealant has been modified in order to have extrusion profile identical to hybrid PU or MS technology. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions.
