Hyperseal ® 25 LM-S U polyurethane sealant

Single-component, thixotropic, polyurethane expansion joint (sealing and adhesive).

HYPERSEAL®-25LM-S is a durable, flexible sealant , ideal for concrete, ceramics, metal and glass . It works great in expansion joints, foundations, water tanks and other places exposed to structural movement. It is resistant to water, mold and extreme temperatures , providing long-lasting sealing and protection.
 
HYPERSEAL®-25LM-S is a low-modulus sealing and adhesive mass based on silylated polyurethane. The bonding occurs as a result of a reaction with air humidity. The product has thixotropic properties. The bonded mass has excellent (50%) accommodation properties. It permanently bonds to almost any type of surface, including those traditionally considered problematic for polyurethane products, such as glass, aluminum, steel, polycarbonates, even without priming.
 
 

APPLICATION


HYPERSEAL®-25LM-S is a single-component sealing and adhesive mass used for:

  • Sealing joints and expansion joints in concrete ,
  • Precast concrete ,
  • Industrial floors ,
  • Water reservoirs and swimming pools ,
  • Joining metal and aluminum panels ,
  • Window and door installation ,
  • Sealing irrigation channels and drains ,
  • Bonding ceramics, glass, granite and marble .

FEATURES AND BENEFITS


  • Flexible and durable coating – retains its properties even with large expansion movements (50%).
  • Very good adhesion to most substrates – does not require priming.
  • Thixotropic formula – facilitates application in various weather conditions.
  • Resistance to microorganisms – not susceptible to the growth of fungi and molds.
  • Can be applied underwater – ideal for tanks and places exposed to moisture.
  • Resistance to extreme temperatures :
    • From -40°C to +80°C ,
    • Stability in sunlight (>60°C) .
  • Very good chemical resistance – can be used in swimming pools, treatment plants and chemical tanks.

HYPERDESMO SYSTEM application guide

APPLICATION


  • Preparation of the substrate:
    • The surface must be clean and free of grease, dust and old sealants.
    • For absorbent surfaces, MICROPRIMER ™ priming is recommended .
  • Application:
    • Application method: caulking gun.
    • For expansion joints the width to depth ratio should be 2:1 , minimum depth is 10 mm .
    • It is possible to use an expansion joint to optimize the layer thickness.
Sealing and bonding of expansion joints
  • precast concrete
  • concrete granite, marble etc.
  • gluing ceramic tiles
  • water tanks
  • swimming pools
  • connecting metal and glass panels
  • filling cracks and scratches
