Hotmelt adhesives are melted in a solid state (e.g. granules), applied to the bonding surface in a hot state and establish a firm bond with the substrate when cooling. Strength is achieved very quickly, immediately after the melt has cooled and solidified. Hot melt adhesives consist of 100 % solids. Hot melt adhesives are mainly used in perfect binders.
EVA hot melt
Hotmelt adhesives based on ethylene vinyl acetate (EVA) are used for a wide range of standard applications due to their attractive price-performance ratio. They are characterised in particular by short open and setting times, have excellent adhesion, even with difficult surfaces. Ideal for high production volumes or low idle times.
PO hot melt
Polyolefin- (PO-) based hotmelt adhesives are used where EVA hotmelts reach durability limits but PUR is not required. Compared to conventional EVA hot melts, they offer a greater overall performance spectrum, such as higher thermal stability, an improved adhesion spectrum or good low-temperature flexibility. The group of PO-based hotmelts is also the most commonly used type for spray-applied bonding.
We supply the PLANAMELT adhesive range from Planatol here. PLANAMELT hotmelts are universally applicable, can also cope with difficult papers and are suitable for all binding work. PLANAMELT ensures process reliability, isocyanate-free and easily recyclable. Due to the low application quantity and savings in maintenance and cleaning of the machines, high economic efficiency is given.
