Waterborne acrylic dispersions as chlorine-free contact adhesive for 2K foam bonding
Waterborne acrylics are widely used for PSA applications like tapes, labels and surface protection films. Whereas, contact adhesives for the foam and mattress industry are mainly based on chloroprene dispersions. Applied on substrates like foam or wood, chloroprene-based contact adhesive dispersions show convincing behavior like instant tack, high green strength and creep resistance.
Synthomer has developed an alternative, chloroprene-free solution based on waterborne acrylic technology as chlorine-free, more ecologically friendly option for the market.
In this presentation, we will showcase uniquely stabilized acrylic dispersions, which can be used for 2K spray applications, just like chloroprene-based dispersions are used today. Furthermore, the newly developed dispersions can be blended with chloroprene dispersions in any ratio as they are fully compatible. This allows the customer to formulate a product for their desired applications and needs.
Our in-house developed test methods show very good initial tack on PU-foam and bonding strength even under restoring forces. Benchmarking the adhesive properties of our acrylic dispersions against chloroprene dispersions, we see this technology as a promising step forward to substitute chloroprene dispersions.
