Description

Sopro PUK 503 PU Adhesive is a two-component, light-coloured polyurethane reaction resin adhesive, for laying and bonding of ceramic tiles, natural and cast stone units, and resin-bonded tiles. The product is particularly suitable for use with wood-based, gypsum-based and metal substrates. Meets enhanced requirements in terms of tensile and shear adhesion strengths, elasticity and water tightness on critical substrates.

Features/ Benefits:

  • High flexibility and adhesive strength.
  • For substrates that are moisture-sensitive and subject to significant deformation.
  • Particularly suitable for application to metal and wood-based products.
  • For walls and floors.
  • For indoor and outdoor use.
  • Meets R2 T requirements to DIN EN 12004.

Applications:

For use with earthenware, stoneware and fully vitrified stoneware tiles, ceramic split tiles and split tile fittings, clinker floor tiles, glass and sintered glass mosaic; calibrated natural and cast stone units, resin-bonded tiles.
