EXPANDER FR

EXPANDER - FR is a suspension of non-flammable substances and modifying additives in a synthetic resin. It has a milky color. Once it is applied to the surface and dries, it creates a transparent colorless coating. Under the effect of high temperatures, the coat starts to swell, creating a foamy insulation layer. Once it is fully dry, the EXPANDER - FR coat is covered with a nitrocellulose varnish called CAPON.

EXPANDER - FR is intended for the fire-retardant protection of construction elements made of wood or wood-based materials (particle board, plywood, OSB board, etc.) used indoors in residential and public buildings, where the relative air humidity does not exceed 70%. The product has the ITB technical approval, the Polish National Certificate of Conformity, the Declaration of Conformity and the PZH (Polish National Institute of Hygiene) Certificate.

• the recipe is based on nanotechnology – the nanoparticles contained in the varnish fill even the tiniest of microgaps, creating a tight and hard coat with excellent fire retardancy parameters
• highly robust system – does not require any maintenance or renovation, the varnish does not lose any of its fire-retardant properties unless it is destroyed or mechanically damaged
• high visual appeal – the varnish is colorless which ensures that the wood protected with it retains its natural look
• non-toxic, completely safe to human health and to the natural environment
• the fire-retardant coat created by the EXPANDER FR and CAPON varnish does not emit any toxic substances to the environment
