Building filters for [...] filters is due to the adhesive used in the manufacturing process of HEPA filters. “Big filter elements contain up to six kilograms of adhesive,” says Dressler. It [...] available, manufacturers pleat the filter media and stabilize it using a hot melt adhesive.” Adhesives like Jowatherm 262.25 based on ethylene-vinyl acetate (EVA) are

for the chemical crosslinking reaction and largely influences the excellent bonding characteristics of those adhesives. However, the diisocyanates can lead to [...] to the formation of monomeric fumes of acute toxicity when the adhesive is melted. Appropriate precautionary measures are therefore necessary to protect the [...] Jowat launched Jowatherm-Reaktant ® MR 604.90, the world’s first PUR hot melt adhesive with hazard-free labelling that is certified according to RAL-GZ 716 for window

A simple change of adhesive, for instance, can help increase their production capacity or alternatively [...] without the need for major investments. Clear benefits: PUR Compared with other adhesive systems for the manufacture of load-bearing timber components, polyurethane

the adhesive must be applied homogeneously to the bonding partner and irregularities in the substrate surface have to be evened out with the adhesive to create [...] Like any other bonding, high-tension bonding is basically a multi layer compound of at least two substrates. Tensions occur only when the bondline is exposed [...] diminishing quality, the adhesive must provide sufficient adhesion to the substrates and the initial strength (i.e. cohesion of the adhesive) must be higher than
