Double-walled PMMA refrigeration doors do not fog, are lighter and more transparent than the glass versions, making them a very good alternative. Due to the importance of transparency for the view of the cooled products, the adhesive must be completely transparent and must also provide a durable bonding, which can handle both temperature differences and the shock load of opening and closing. In addition to drawing up a product application specification for the adhesive, the purchasing procedure for the adhesives has also been optimized. With the product/production specification, potential adhesive suppliers can better tailor their product to the wishes and requirements of the manufacturer. Rich-Bond is perfectly capable of initiating and accompanying this process.
