EKOPRODUR KW1 is a two-component polyurethane adhesive (PU or PU) for the production of sandwich panels. The adhesive consists of a polyol mixture in the form of an oily straw to yellow liquid (component A) and a mixture of aromatic polyisocyanates, mainly diphenylmethane diisocyanate, brown coloured (component B). Both components are free of suspensions.

The system is designed for the production of sandwich panels with a core made of expanded polystyrene, mineral wool and polyurethane. The adhesive system is relatively fast, it requires even and accurate distribution on the surface. It is dedicated primarily for manufacturers of sandwich panels on continuous production lines. Permanently bonds painted sheet metal with boards made of polystyrene, polyurethane (also polyisocyanurate plates, PIR) and mineral wool.

The glued surfaces should be dry, degreased and free from dust before applying the adhesive. The conditions for the processing of glue must be adapted individually to the production conditions, production line parameters and the type of bonded materials.

In addition, both components of the adhesive are characterised by a reduced emission of volatile organic compounds (VOC), as they do not contain foaming agents, which significantly deplete the ozone layer – in accordance with European Union regulations, Regulation (EC) No. 1005/2009 of 16.IX.2009.

Main application advantages of the product:


  • fast and durable joining of painted sheet metal with polyurethane board and polyisocyanurate board,
  • fast and durable joining of painted sheet metal with a Styrofoam block,
  • fast and durable joining of painted sheet metal with a mineral wool block,
  • gluing on a continuous production line.

Mechanical properties of the two-component polyurethane adhesive EKOPRODUR KW1:


  • optimal temperature of raw materials during gluing: 18-22 ° C,
  • optimal sheet metal temperature before dosing ingredients: ≥ 20 ° C,
  • press temperature: 30-40 ° C,
  • The average spreading capacity of glue is 250-350g / m2 of finished panel.

In order for the adhesive to maintain its stability and parameters, the glued surfaces should be thoroughly dried, degreased and cleaned of dust. It is recommended that other processing conditions be agreed directly with the technologists, as the conditions must be adapted to specific production requirements, line parameters and the type of materials to be bonded.
