Application areas

It has a good adhesive strength without primer on most common materials, such as aluminum, zinc, galvanized steel, stainless steel, copper, natural stone, concrete, brick, etc. For crystal clear elastic bonding in construction and building applications. Invisible bonding and sealing of glass and other transparent materials in indoor applications.

Standards

Meets or exceeds the requirements of the following specifications: CE marked for EN 15651 for façade applications.

  • The requirements of VOC content specifications in LEED credit EQc4.1
  • “Low-emitting products” of SCAQMD rule 1168.
  • The French VOC requirements for class A+
  • CE marked for EN 15651 for façade & glazing applications (DOP NO: 2016-0004).

Restrictions

  • It must not be used in totally confined spaces where sealant cannot cure due to lack of atmospheric moisture.
  • Cannot be used on natural stone. Because the adhesion surface will discolor under influence of the sealant (looks wet) also this is visible through the sealant due to its clear look.
  • Do not use it in applications where continuous water immersion is possible.
  • Prolonged exposure to direct sunlight can cause discoloring, Joint Width 5mm 10mm Joint Depth 5mm Efficiency /310 ml 12 meters 6 meters
