KLEIBERIT offers a complete product range for all types of profiles and films, in addition to decades of experience. The adhesives and primer systems of KLEIBERIT are suitable for interior and exterior solutions for PVC and ALU profiles, surface finishing, windows seals and profile foaming.
PVC Profiles
The requirements on adhesives and primer systems for wrapping PVC window profiles are immense. KLEIBERIT offers a complete product range for all types of profiles and films, in addition to decades of experience. The KLEIBERIT product range focuses on the requirements of the new RAL GZ 716 as well as manufacturer requirements regarding faster and safer processing. KLEIBERIT hotmelt adhesives based on polyurethane (PUR) have very good hydrolysis/thermolysis properties and an extremely wide processing window. These adhesive systems are perfectly compatible with all RAL GZ 716 certified KLEIBERIT primers for pre-treating PVC profiles.
For example, the low-VOC primer KLEIBERIT 840.3, without NEP additives on polymer basis, with fluorescent formulation for controlling application on the entire surface, visible under UV light. Modern primers can be applied with felt and vacuum application technologies.
Aluminum Profiles
Over the last 25 years, reactive PUR hotmelt adhesives have been become prevalent – they fulfill all of the requirements concerning windows, e.g. very good hydrolysis/thermolysis properties, and also have the best processing properties. For the lamination of aluminum window profiles, the PUR HM KLEIBERIT 704 series has especially set a quality standard in the market , particularly due to excellent aging resistance. Certified according to RAL GZ 716. KLEIBERIT also offers a complete range of RAL GZ 716 certified Primers, e.g. the KLEIBERIT 831 series, with fluorescent formulation for controlling application on the entire surface and very fast evaporation.
Profile Foaming
Energy efficiency is a key factor in window construction. The insulation values of intelligent profile systems and glazing technologies are significantly increased with the use of special polyurethane foams. KLEIBERIT offers 2C systems with very good processing and interesting properties, specifically for profile foaming (PVC / aluminum) applications. The foam doesn’t stick with the profile material, spreads through the chamber systems during expansion, and is completely recyclable.
Surface Finishing
In addition to the technical and structural requirements in window technology, there are also new trends and ideas concerning the visual aspects. For example, PVC / ALU profiles for interior use can be laminated with real wood veneer, which has been pre-coated with HotCoating. The finish enables pre-coated veneers to laminate even the tightest radius without cracking. For digitally printed papers or films, HotCoating surfaces offer surface protection, prevent colors from fading and are extremely climate resistant. Due to the flexible properties of HotCoating surfaces, 3D structures can be embossed shortly after coating , e.g. to imitate wood grains.
Window Sills
KLEIBERIT offers a complete range of primers and adhesives. These adhesives feature tremendous water, heat and cold resistance. Especially in the field of window sill lamination, the PUR HM KLEIBERIT 704 series has established a quality standard in the market, in particular due to excellent aging resistance. Can be combined with all RAL certified primer systems.
