Rafz, Switzerland – Alfa Klebstoffe has launched a new range of Simalfa chloroprene-free adhesives for flexible polyurethane foam.
The CR-Free range are one- and two-component systems. A wide range of materials used in the polyurethane foam converting and upholstery industries can be bonded with the products.
Good wet adhesion and good heat resistance are two characteristics of the water-based contact adhesives.
There are three halogen-free grades in the range.
The first, Simalfa 260 is solvent-free and designed to be applied by a roller. High instant tack, and fast drying are key characteristics of this product. The mattress industry will be this product’s home, said Alfa Klebstoffe.
The 3701 material is aimed at foam processors which need to use a roller to apply the adhesives. The two-component product is repositionable, with high instant tack, high yield and can be applied double sided.
Finally, the company’s 3702 product has similar characteristics to the 3701 product, but it is designed to be applied successfully by spray, rather than roller.
All of the grades are yellowing and ageing resistant.
