Polyurethane Sealants:

Innovation has taken another step forward and our offering of polyurethanes from 3M satisfies many tasks that previously have been almost but not quite there in performance values.

Used via caulking gun applicators or sausage sachet packs which you knead directly onto the seam or joint (contact us for more information on this) this grade of urethane sealants offer robust, permanent and flexible bonds.
The advantages are:

  • little bubbling, expansion or foaming.
  • little bleeding, staining or shrinkage
  • very flexible and perfect for sealing dissimilar materials together.
  • paste like consistency enabling gap-filling features.
