Aluminium Spacer Bar from 6mm till 24mm, standard, bendable and butyled.

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 is producing polyisobutylen based primary sealants, KU-83B and PIB-996 for insulated glass industry in Eskisehir/Turkey and Moers/Germany. NEDEX butyl sealant is especially designed to reach very low gas and moisture penetration rates. Butyl is also known as a solution for internal insulation in insulated glasses. It has one black component and without solvent. It has good adhesions properties to glass and metal. NEDEX butyl can be packed in slugs and cans as 7 kg (standard); 2,5 kg and 1 kg. NEDEX insulating glass primary sealants KU-83B and PIB-996 are for Insulating Glass Units with specifications according to EN 1279:2018.
