Application Description

Jowapur® Appretur - Upgrade First Class

The physical characteristics of wood-based materials such as MDF and HDF can be improved significantly with the Jowapur® Appretur. This provides the opportunity to tap into new markets and fulfil the increasing requirements for the latest applications, and to achieve higher resistances. Especially the tensile strength, shear strength, bending strength, E modulus and transverse tensile strength can be increased by up to 100 %.

Finishes are applied to fabrics, textiles, yarns, and fibres to impart the required functional properties. For instance, they can be used to improve the surface structure, rigidity, strength, gloss, density of the substrate, but can also function as a hydrophobic, antistatic, flame-retardant, or antimicrobial Agent.

The treatment of wood-based materials with a hydrophobing agent makes them either water-repellent or at least reduces the water absorption. The ingredients of the Jowapur® Appretur cover the wood fibres, pores and capillary surfaces, therefore preventing moisture ingress. Since the pores and the capillaries are not closed in this procedure, the diffusion capacity (breathability) of the material remains virtually unaffected by the hydrophobing treatment.

The Jowapur® Appretur is suitable for instance for the following substrates: MDF/HDF, particleboard, plywood, solid wood, plaster and cement fibreboard, paper, cardboard
