Modern adhesive systems for established processes
The manufacture of upholstered furniture is characterised by a huge diversity of processed materials. Apart from cold and preformed foams, textiles, leather, wood or wood-based substrates, various plastics and many other materials are used. Frequently, the operations are manual and the process times vary widely. The combination of a long open time, good adhesion to the various substrates, and high green strength, represent a great challenge to adhesives technology. For decades, the solvent-based Jowatac® adhesives have been established in the upholstery and foam cutting industry and have constantly been adapted to the respective requirements. The adhesives are usually applied by spray gun. The solvents in these cases serve as processing aides which evaporate during spray application and afterwards. Solvent-based adhesives facilitate fast application and assembly processes due to high green strength, especially in high-tension bonding, short pressing times with little pressure and a fast build-up of cohesion, and are therefore the basis for efficient, labor intensive manufacturing.
In order to meet the increasingly more stringent environmental and safety standards, Jowat SE had already developed solvent-based adhesives over 25 years ago that offered a lower solvent percentage and a much higher solids content. Apart from lower solvent emissions, solvent-based adhesives with a higher solids content offer a cost advantage due to higher yield and therefore significantly reduced material costs per part. Solvent-based adhesives have for decades now been providing a major input into resource conservation and environmental protection, and facilitate sustainable and environmentally compatible upholstery furniture.
