DESCRIPTIONHYPERSEAL®-25LM-S 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. It has been modified in order to give enhanced thixotropic properties.It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor and excellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum,steel, polycarbonate, etc.. 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.The sealant is easy to apply even in very low temperatures and the storage stability is unlike any polyurethane sealant in the market.COMPLIANCE WITH• ISO-11600,• Type F - class: 25LM,• DIN-18540-F,• ASTM C920,• U.S. Federal Specification TT-S-00230C,• Type II Class A.RECOMMENDED FOR Sealing joints in:• Insitu concrete,• expansion concrete plates,

One component, polyurethane-based, low modulus joint sealant ideal for use in high humidity conditions

DESCRIPTIONHYPERSEAL®-expert is a novel low modulus expansion joint sealant, especially formulated to ensure bubble free cure even at very high temperature and humidity climatic conditions. The product displays excellent thixotropy allowing its use even in very large expansion joints.It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor andexcellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum,steel, polycarbonate, etc.. The extrusion rate and tooling of the sealant remain the same throughout a very wide range of temperature and humidity conditions.COMPLIANCE WITH• ISO-11600,• Type F - class: 25LM,• DIN-18540-F,• ASTM C920,• U.S. Federal Specification TT-S-00230C,• Type II Class A.RECOMMENDED FOR Sealing joints in:• Insitu concrete,• expansion concrete plates,• precast panels,• brick and block work,• water tanks and swimming pools,• metal frames,• aluminum windows and panels,• irrigation channels,• glass,• granite & marble.LIMITATIONS• Not recommended for direct application onunsound substrates.In this case the substrate must beprimed with MICROPRIMERTM, which will reenforcethe concrete and produce a strongdurable substrate for sealant application.• Highly porous substrates, dusty surfaces or poorly compacted concrete, must have their porous bond area surfaces thoroughly sealed to avoid the possibility of air bubbles being blown into the uncured sealant if the substrate temperature rises.FEATURES & BENEFITS• No bubbling/swelling upon curing in difficult climatic conditions.• Excellent Thixotropy• Excellent adhesion on almost any type of surface, with or without the use of special primers.• Excellent extrusion, tooling and storage stability over wide range of climatic conditions.• Excellent chemical resistance, suitable for sealing joints in swimming pools and chemically treated water.• Low modulus, joint movement accommodation50%.• Microorganism and fungus resistant.• Excellent heat resistance, suitable for application where exposure to temperatures>60°C take place.
• Resistance to cold: The sealant remains elastic even down to -40 oC.
