StoragePoly (methyl hydrosiloxane) has a shelf life of at least12 months when stored at 25 °C in the tightly closed original container. The 'Best use before end' date of each batch appears on the product label.Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance Reasons.Safety precautionsIn the event that H-siloxane splashes onto or is soaked up by the insulating material, the insulating material must be changed immediately. Please see our safety data sheet.Safety informationDetailed safety information is contained in each material data safety sheet, which can be obtained from our sales offices.
