New formula: Thermoplastic adhesives for high-quality lamination of wood-based substrates – for general use with all common laminating machines using in- or offline application.
Whether inline or offline method: The latest developments from the product family of Jowat-Toptherm® permit a homogenous adhesive application without any striping effect. Depending on the quality of the surface of the specific wood-based panels, low application grammages can be realised. A highly smooth and even surface, combined with superior compound strength, is achieved.
In contrast to the conventional thermoplastic EVA systems, these new formulations based on polyolefins allow to create adhesive bondlines with a degree of hardness tailored for specific applications – ranging from medium hardness to very hard. Therefore, a superior surface quality is also maintained in cases when ambient temperatures are high and simultaneously severe mechanical stress is exerted on the freshly laminated parts – e.g. stack pressure directly after manufacture.
These new members of the product family of Jowat-Toptherm® are free of formaldehyde and in comparison to dispersion adhesives hot melt formulations do not contain water. Any possible swelling of the wood-based substrates is therefore prevented, resulting in a significantly improved smoothness of the surface, with the additional advantage of shorter process intervals.
