Polysulfide Sealant

NEDEX insulating glass secondary sealant PS-002 is a 2-component, solvent-free adhesive/sealant with SH-bonding ends (polysulfite). The rheological properties of the product make it suitable for manual and robot processing. PS-002 adheres to glass, aluminium, galvanized steel and stainless steel without the use of primer. For other products, such as coated glass, glass from which the coating has been removed, treated spacer profiles or profiles made of other materials; relevant trials must be carried out to ensure the product's suitability. The use with polycarbonate or polymethyl methacrylate (PMMA) is not recommended. It is produced only for insulated glass manufacturing. For different applications please contact NEDEX Technical Department. Very low gas and moisture penetration rates High adhesion to aluminium and glass surfaces Long potlife times and Short curing times

NEDEX insulating glass secondary sealant KU-83 is a 2-component, solvent-free adhesive/sealant with SH-bonding ends (polysulfite). The rheological properties of the product make it suitable for manual and robot processing. KU-83 adheres to glass, aluminium, galvanized steel and stainless steel without the use of primer. For other products, such as coated glass, glass from which the coating has been removed, treated spacer profiles or profiles made of other materials; relevant trials must be carried out to ensure the product's suitability. The use with polycarbonate or polymethyl methacrylate (PMMA) is not recommended. It is produced only for insulated glass manufacturing. For different applications please contact NEDEX Technical Department. KU-83 is an outer sealant for Insulating Glass Units with specifications according to EN 1279:2018. Very low gas and moisture penetration rates High adhesion to aluminium and glass surfaces

NEDEX secondary sealant MELTEX hotmelt butyl (hot melt sealant) is a 100% solids, single-component sealant designed for the sealed insulating glass industry. It is formulated from butyl rubber, synthetic polymers and elastomers to give outstanding adhesion to glass and aluminum when fabricated manually or reactivated in semi- automatic equipment. The product is resistant to degradation from ultraviolet light, temperature extremes and water immersion. MELTEX hotmelt butyl is is compatible with inner sealants of NEDEX such as KU-83B and PIB-996. They can be used together, there will be no chemical reactions. Before using MELTEX together with other inner sealants chemical compatibility tests should be done. MELTEX is a secondary sealant for Insulating Glass Unit with specifications according to EN 1279.

NEDEX is producing polyisobutylen based hotmelt secondary sealant MELTEX for insulated glass industry in Istanbul/Turkey. It is specially designed to reach very low gas and moisture penetration rates. Just as butyl sealant, hotmelt secondary sealant is one component sealant for IG units. NEDEX hotmelt sealants have very good physical and chemical properties, is easy to process, and ensures optimal resistance to low and high temperatures. It has good properties in terms of resistance and adhesion. Gas leakage rate is optimized with NEDEX hotmelt. NEDEX hotmelt sealant is completely suitable for IG units with good energy efficiency.
