used in all climates, in every season. In Europe, this is normally achieved through the use of liquid applied moisture cure polyurethanes. Alternative technology includes 2-component Polyurethanes, mainly used for premium brands, and reactive hot melts, which are more common in the US market. H.B. Fuller supplies both types of adhesive technology.
As 1-component PUR and MS-Polymers need the right level of humidity during the curing process, seasonal differences are a challenge in most markets. For example, in cold winter weather, the curing process will slow down, which can impact the timely supply of parts to the production line. In the worst case scenario, the adhesive may not be fully cured when leaving the production hall. Thankfully, this problem can be overcome by using the elastic material as a 2-component material instead of a 1-component material. This requires the use of a second component containing moisture and will satisfactorily ensure fast and safe curing, no matter what the weather conditions are on site. H.B. Fuller can even create a tailor-made customer solution with different reaction speeds to ensure the production process is as efficient and predictable as possible.
2-component MS-polymers, such as Körapop 225/2-part, which is developed and produced by Kömmerling in Germany, are environmentally friendly as they are free of isocyanates, PVC, solvents and silicone. They react to a permanent high elastic adhesive line and provide good adhesion on various materials, including metal or plastic parts, painted surfaces and wooded layers.
