High-temperature sealing compound wezi-lit W 1000 was honoured by a firm place in the New York „Hall of Fame of Innovative Materials“

Since decades the Hessisch sealing technology-expert WEBER dominates the high-temperature-sealant-market with its specialities.

The Hessisch sealant expert Weber Plastics Technology once again achieved an important international business success. The experts have been honoured for its high temperature sealing compound wezi-lit W 1000 with the „Certificate of Material Excellence“. This in-house development of the water-glass based wezi-lit W 1000 is the first high-strength and up to 1000 º C resistant pasty sealant without separation. Since years this product is sucessfully field tested and conquered sizeable markets. The material experts of the independent New York based „Material ConneXion – Institute“ just recently testified, that  wezi-lit W 1000 is innovative, shows excellent properties and is multifunctional applicable.

Since more than sixty years Weber is the expert for the development and production of high-temperature sealing compounds of the trade mark wezi-lit. Furthermore the company is well-known in another business line with plastics technology as supplier and solution provider.
„Material ConneXion is a worldwide renowned testing-, observing- and information source for innovative, future-oriented materials and processing-methods. Important criterions for their choice of materials: Technological progress, enviromental impact, safety, and the variety of application.

The successful product  - wezi-lit W 1000 -, consisting of water-glass and enriched with high-grade mineral fillers, shows since many years significant market – shares as special oven - and boiler - sealant by leading heating system manufacturers.

According to Material ConneXion the potential of the sealant wezi-lit W 1000 is still not yet exhausted by far. The Weber sealing compound especially attracted attention because such a high-temperature material-type with multifunctional application has not yet been registered in the World Archives of Material ConneXion.

Due to this there will be new customer-groups and new applications for Weber all over the world. As a full service supplier, from the customer service to the developping of specific formulations and down to the production Weber will be always the ideal partner for customised solutions. In the past, thus many complex problems have been „permanently tightened“.

Technical highlights of the high-strength W 1000:

  • long shelf life in several kind of containers (barrel, cartridge and others)
  • unique: no separation into liquid and solid mineral components inside the cartridge
  • minimum storage period of the originally unopened cartridge is12 months after production
  • optimal dosage, especially by means of cartridge or spraying pistol
  • good adhesion-behaviour to many substrates
  • after drying the material will be high strength
  • used as asbestos replacement, especially also in brighter shades e.g. for controlling and monitoring temperature in special devices and in special heating systems
  • successfully tested during decades at 1 000 º C  in cast iron boilers, ovens, furnaces, fireplaces, flue-gas pipes, and for fixing brick-linings of combustion chambers. Customers are amongst others Buderus, De Dietrich , Demir Dökum, Vaillant and Viessmann
  • particularly suitable for oven - and chimney - manufacturing and restauration

Other wezi-lit achievers with elastic performance:

  • silicone-freee sealants for temperaures up to 250 º C
  • different silicones up to 300 º C
  • optimal dosage, especially by means of cartridge or spraying pistol
  • good adhesion-behaviour to many substrates
  • after drying the material will be very elastic
  • successfully tested over decades in cast iron boilers. Customers are amongst others Buderus, De Dietrich , Demir Dökum, Vaillant and Viessmann
