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.

NEDEX produces solvent-free primary sealant PIB-996 based on polyisobutylene for the insulating glass industry. The formulation has been specially developed to achieve very low gas and water vapor penetration rates. The product is compatible with Nedex secondary sealants. The solvents most commonly used in the formulations of secondary sealant formulations based on polyurethane and polysulfide show no signs of migrations with Nedex primary sealants. However, intensive compatibility tests according to EN1279-4:2018 should be carried out before use if PIB-996 is not used together with Nedex secondary sealants PS-018 and KU-83. PIB-996 has a very good adhesive properties on glass and metal. The effect of heat leads to a significant softening of primart sealants. Neverthless, PIB-996 shows good stability even at temperatures around 100°C and does not flow out of their position into the space between the panes. PIB-996 has also been certified according to EN1279-4:2018.

NEDEX insulating glass secondary sealant PS-018 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-018 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. PS-018 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 Long potlife times and
