Polyurethanes

Polyurethanes are a treat that chemistry gives us. They are flexible and tough materials with high performance under different climate conditions, but always adhesive and waterproof.

Gairesa manufactures a wide variety of polyurethane systems developed for specific problems and special requirements, providing expert solutions:

 •    GAIDUR® COATINGS Series
Polyurethane formulations for elastic membranes and weather and UV-stable sealants.

•    LARBOND® PU Series
Polyurethane formulations for structural or flexible adhesives.

Some examples of our polyurethane products are mentioned below. To find the product that fits the best with your needs, please contact us.

Within the GAIDUR® COATINGS Series there are different weather and UV resistant coatings like GAIDUR® P AB (the high gloss version within this line of products). Other UV-stable sealants are GAIDUR® P MATE or GAIDUR® P TRANSPARENTE. All grades of this UV resistant coating, matt or gloss, are available in a wide range of colours (RAL colour chart).

LARBOND® PU Series comprises flexible and structural adhesives. For example, LARBOND® F,M 4002 PU behaves well on flexible substrates because it was formulated to bond to thermoplastics. In contrast, LARBOND® 4003 PU has a higher Tg and elastic modulus, as well as excellent cohesive properties and outstanding adhesive properties. The values of lap shear strength on aluminium can be as high as 30 MPa.
