ELASTOSIL E43 RTV-1 SILICONE RUBBER / ADHESIVE Product description Storage ELASTOSIL E43 is a self-levelling one-component The Best use before end date of each batch is shown silicone rubber with very good mechanical properties, on the product label. which cures at room temperature under the influence of atmospheric moisture. Storage beyond the date specified on the label does not necessarily mean that the product is no longer Special features usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons. - acetic acid-curing system - self-levelling Safety notes - excellent primerless adhesion to many substrates During vulcanization of ELASTOSIL E43, a total of 4 % by weight of acetic acid is split off. These vapours Application should not be inhaled for long periods or in high concentration. Work areas should therefore be well - multipurpose glue ventilated. Contact of unvulcanized silicone rubber with eyes and mucous membranes must be avoided as this would cause irritation. However if it does happen, rinse Processing the affected area thoroughly. ELASTOSIL E43 shows good primerless adhesion to Comprehensive instructions are given in the many substrates. We recommend running preliminary corresponding Material Safety Data Sheets.
