OWL Lava 20 PU Mastic 600cc

It is a fast curing joint sealant suitable as a general adhesive when applying the Owl Lava20 system.

Best Uses:

  • sealing connections in metal frames,
  • aluminum windows and panels,
  • glass
  • granite and marble or for flooring applications.

Owl Lava20 PU Mastic is a fast-curing joint sealant, a universal adhesive that has been specially formulated to contain both PU and silylated PU. Due to the nature of the sealant's composition, it has the best properties of both technologies. The material has been modified to provide better thixotropic properties.

  • Excellent adhesion to almost any type of surface, with or without the use of special primers
  • Excellent extrusion, tooling and storage stability over a wide range of climatic conditions
  • Excellent chemical resistance, suitable for sealing joints in swimming pools and chemically treated water
  • Resistant to microorganisms and fungi
  • Application possible in immersion in water
  • Excellent heat resistance, suitable for use in locations exposed to temperatures> 60 ° C
  • Cold resistance: The packing remains flexible even down to -40ºC.

Owl Lava20 PU Mastic cures quickly in reaction with atmospheric moisture, creating a sealant with excellent early adhesion, even on substrates that have traditionally been a problem for PU sealants such as aluminum, steel, polycarbonate, etc.

Recommended Product Application OWL Lava 20 PU Mastic instructions:

  • Thoroughly clean the connector and make sure that there is no oil, grease and wax contamination, silicone residue. For many applications, no primer is required. In this case, when applying on very porous substrates, carefully glue the surfaces to avoid blowing air bubbles into the uncured sealant when the temperature of the substrate increases. The recommended foundation is Owl Lava Prime.
  • Although both types of stick are recommended, care should be taken when using a closed-cell polyethylene stick to avoid puncturing the outer coating as this may cause bubbles when the temperature rises. The use of a shim is important to ensure that the correct width-to-depth ratio is obtained, providing a firm base on which to remove the sealant.
  • Slide the sealant into the gun, snip off the very end of the sealant pack, and align the gun with the nozzle you cut to obtain the correct stitch size.
  • Squeeze the sealant into the joint making sure there is no air in it. Wide weld seams require more than one gun pass to ensure the sealant is in full contact with the sides and bottom of the weld.
  • The ratio of width to depth should be 2: 1, subject to a minimum depth of 10 mm.
  • when applying on very porous substrates, glue the surfaces thoroughly to avoid blowing air bubbles into the uncured sealant when the substrate temperature rises. The recommended foundation is Owl Lava Prime.
