Fire-resistant adhesive for façades

We have developed an adhesive to bond a non-woven material with a film for façade insulation. The flame-retardant adhesive demonstrated high bond strengths on fleece and film.

Bonded materials: Non-woven material with a permeable film

Client: Manufacturer of non-woven materials

Sector: Construction supply industry

Medium: Powder

Polymer: Ethylene vinyl acetate (EVA)

Project duration: approx. 2 years

The challenge

The client would like a flame-retardant adhesive with high bond strength on fleece and film. It must also have thermal stability at 60 degrees but should not have a much higher melting point so that the non-woven material substrate does not shrink. The adhesive must also be weatherproof.

The path to our solution

With a low-viscosity EVA we were able to obtain very good adhesion results and weatherproof properties. We then made additional modifications to the polymer with flame retardants.

The solution

The client purchases our adhesive and uses it for regular sales of their product in the construction industry in Scandinavia. They have now also found a sub-dealer. The adhesive is certified and must not be altered, as it was used to pass all of the weather and fire safety testing.

The project has been concluded and was a success for both Abifor and the client.
