  • Description

    UC 105 is a one-part moisture cured, clear, aliphatic polyurethane primer for use as supplied. It is clear, non-yellowing and is specifically formulated to improve the adhesion of polyurethane and poxy compounds onto ceramics, masonry, natural stone, and brick substrates.

    Application

  • Transfer a portion of UC 105 into a clean container.
  • Tightly seal the original container to prevent the contents gelling.
  • Apply a thin coat of primer by brush and allow the solvent to evaporate before applying coating or sealant.
  • Once the primer loses its tackiness, re-prime.
  • Surface Preparation

    The correct preparation of the surfaces is critical.

  • All surfaces should be clean, sound, and dry, and all laitance or surface contamination should be removed by wire brushing, grinding or grit blasting.
  • Vacuum or blow with compressed air to ensure total removal of dust.
  • Product Application

    As a primer coat under UC epoxy and polyurethane compounds, when used in paving, curtain walls, expansion joints in tiled areas, and between pre-cast units.

    Cleaning

    Clean brushes after use with UC 901. Once cured the primer may only be removed mechanically.

    Safety
