Munich, December 5, 2014 – Chemical Group WACKER is presenting two new silicone sealants for the local construction and glass industries at the Indian ZAK Glass Technology 2014 tradeshow: WACKER® SG 79, a structural-glazing silicone for onsite installation, and weathering-resistant sealant WACKER® WS. These two products round out the extensive sealants portfolio that the company is showcasing at the tradeshow. ZAK Glass Technology 2014 is taking place in New Delhi, India, from December 5 to 7.
Adhesives and sealants used on glass facades and exterior walls of buildings are exposed to extreme environmental impacts. They must withstand heat, frost and UV radiation, as well as rain, aggressive salts and industrial emissions. The mechanical stresses are also substantial. Construction materials such as concrete, steel or glass deform quite differently in response to rising or falling temperatures, which results in surface tension and movement between the facade and supporting elements. Sealants are thus exposed to permanent mechanical stress for years – and no sealant can cope with this better than silicone sealants from WACKER.
Glass facades, especially in Asia, are increasingly mounted and bonded at the construction site. At ZAK Glass Technology, WACKER is presenting a new silicone sealant specifically for on-site installation. WACKER® SG 79 STRUCTURAL GLAZING is a one-component, neutral-curing silicone sealant that cures rapidly once it reacts with atmospheric moisture. Fully cured, the sealant can be stretched by up to 500 percent. This allows the product to compensate movement within a joint by up to 50 percent of the gap width.
WACKER® SG 79 defies temperatures between –30 °C and +80 °C and is thus suitable for structural-glazing applications in various climate zones. The product cures virtually without odor and can be processed at temperatures ranging from 5 to 40 °C. WACKER® SG 79 adheres excellently to all conventional building materials such as glass, steel, concrete or stone, even without a primer.
WACKER® WS for Curtain Walls
The second product highlight that WACKER is showcasing at the ZAK Glass Technology is WACKER® WS WEATHERSEAL SUPERIOR. This is also a neutral-curing sealant. It was specifically developed for natural stone and does not stain stone or ceramic joint edges.
Even without a primer, WACKER® WS adheres to both porous and smooth materials, as well as plastics. The sealant cures within 30 minutes and is elastic, extremely robust and weathering- and UVresistant. The product is ideal for sealing and installing large curtain walls and elaborate panel structures.

In view of the current tightening of greenhouse gas (GHG) emission ambitions in Europe, it is with great pride that DSM and Fibrant announce the accomplishment of a major reduction in the GHG emission of Caprolactam and thus subsequently also of PA6 as produced in Europe by July 2021. The GHG emission saved is estimated to be around 800 million kg CO2 on annual basis. This significant reduction has been achieved by implementing several technology improvements amongst which an advanced N2O abatem Read More
