Solar collectors glue and seal securely

With the new 1K and 2K silicone adhesives and sealants from Tremco Illbruck, thermal collectors can be produced faster than using EPDM sealing profiles, with high product quality and a safe process. As new developments for the proven Pactan brand, they convince in use with their extreme durability and weather resistance and with the permanently secure and flexible connection of glass and element frame.

The silicones are suitable for manual, automatic and automated bonding, particularly exposed joints. High temperature resistance as well as UV and weather resistance for long life and function of the joints and the collector are guaranteed.

The two-component 1 adhesives and sealants have a wide variety of substrates and are suitable for example for bonding of glass and frame or the back wall. They quickly build on strength and are temperature resistant up 160 ° C. The movement capacity of the joints during thermal cycling is very good. Which ensures the longevity of the joint and the permanent functioning of the collector. A precipitate in the element interior and performance degradation is avoided by the very good outgassing. While Pactan 7020 by a long pot life is characterized, which allows manual correction and smoothing easy Pactan 7021 impresses with its ambient and layer-dependent curing under 24 h His movement capacity is very high, especially the wide variety of substrates.

The two-component silicones 2 Pactan 8070 and Pactan 8071 provide extremely fast buildup of strength and short cure time. Thus are possible consequences of stroke among 90 s. The need for costly Aushärtungsstrecken unnecessary, and after a few minutes palletize the collectors. The high process reliability is the mixing ratio of the patented system of 1: guaranteed 1 whose A-component is set to self-cure. In handling preserve unfilled, non-abrasive adhesives and sealants pumps and dosage and can solventborne flushing will be replaced by the A-component, thus creating no hazardous waste. The products are high temperature resistant up to 250 ° C. As the 1-component sealants they are suitable for machine and automatic gluing and are characterized by a wide range of adhesion and excellent movement recording at Temperaturwechselnauf.
