Application Description

Whether as decorative cladding panels or as part of heat insulation – modern composites and sandwich elements play a key role in many applications. Intelligent high-performance adhesives have become indispensable in the manufacturing of these products due to the wide diversity of material combinations which have to be joined to meet different specifications. The broad spectrum of adhesion provided by special Jowat adhesives is essential to bonding different substrates such as wood, mineral materials, concrete, plastics and various insulation materials like mineral fibre, foams or aluminium foil. Apart from this, they also meet additional requirements regarding hydrolysis resistance, thermal stability, or fire protection. In addition to reactive polyurethane hot melt adhesives and one-component PUR prepolymer adhesives with different open times and initial strengths which have been tried and proven for many years in the manufacture of high-performance composite elements, two-component SE polymer adhesives from Jowat have also become established in this application. Adhesives from the latter product group are characterised by excellent adhesion, high strength, and permanently elastic bondlines which absorb the tensions between the materials in sandwich structures. Due to this, Jowat® SE polymers are reliable general-purpose products for manual and industrial assembly processes.

Jowat® SE polymers are two-component adhesive systems, which build a bridge between the powerful epoxy resins and the MS polymers with excellent adhesion properties. The full strength of this adhesive system is shown especially when difficult to adhere to surfaces must be bonded that are exposed to high stress. Due to the permanent elastic characteristics of the adhesive, these systems also reliably join substrates with different elasticity coefficients. Jowat® SE polymers are free of isocyanates and solvents.
