GMI - -25 C to -40 C - S-IGL-1942

Mixed 2-component sealants and adhesives have the characteristic to vulcanise slower at lower temperatures. With poly-sulfide and polyurethane the reaction stops at a temperature of - 25 °C, silicon reacts more slowly at a temperature of - 40 °C and lower. Freezing is an environmentfriendly and economic method in case of production interruptions. Gemischte zweikomponentige Dicht- und Klebstoffe haben die Eigenschaft bei niedrigen Temperaturen langsamer zu reagieren. Bei Polysulfid und Polyurethan stoppt die Reaktion ab - 25 °C, Silikon reagiert ab - 40 °C kaum noch. Das Einfrieren ist ein umweltfreundliches und wirtschaftliches Verfahren zur Überbrückung von Produktionsunterbrechungen. Advantages This procedure hinders polymerization of the mixed material due to cooling down on low temperatures. The material can be processed normally after defrosting on temperatures between 20 °C and 50 °C. Please observe the freezing temperature and time specific for each material. ■■ material saving, no jetting of the mixing pipe with A component necessary ■■ solvents for cleaning the mixing pipe are unnecessary Typical freezing parameters: polysulfide at -25 °C some weeks polyurethane at -28 °C some days silicon at -40 °C approx. 60 hours
