Foam technology Macro Foam is a range of melters for generating foaming adhesives using a 50-50 mixture of adhesive and gas. Meler’s systems with foam technology allow: Longer open times: foaming adhesive has longer open time, allowing the use of a larger number of adhesives. Volume increase: after application, the adhesive increases its volume, improving its capacity for incrustation in the holes and pores of the substrate. Greater penetration capacity: stronger bonds are created with foaming adhesives. Foam technology Reduced adhesive consumption: up to 65% depending on the adhesive used Reduced adjustment time: assembly line speed and production rates are increased Vertical application: greater consistency on vertical surfaces Improved performance and saving Foam technology achieves a greater application volume and a reduction in adhesive weight and consumption of up to 65%, improving performance and reducing costs
