It is important to follow certain steps when switching hotmelts as different adhesives types used together can cause unwanted chemical reactions. To prevent any problems the adhesive changes should be carried out very carefully. When changing to a new adhesive e.g. from an EVA to a polyolefin you must first carry out thorough cleaning due to the chemistry of the different adhesives to prevent later problems such as gelling, charring and blocked filters and nozzles. It’s important to avoid charging adhesives regularly. If a change is needed Intact can help you prevent these unnecessary downtime issues by carrying out the cleaning for you using our highly experienced hotmelt engineer.
