5 Insome cases these aqueous washes can affect the cure andperformance of the Product is not normally recommended for use on plastics(particularly thermoplastic materials where stress cracking ofthe plastic could result). Users are recommended to confirmcompatibility of the Product with such for useFor best performance surfaces should be clean and free ofgrease. The Product is designed for close fitting flanged partswith gaps up to Apply manually as a continuousbead or by screen printing to one surface of the flanges. Lowpressures (< ) may be used when testing to confirm acomplete seal immediately after assembly and before should be tightened as soon as possible afterassembly to avoid shall be ideally stored in a cool, dry location inunopened containers at a temperature between 8 C to 28 C(46 F to 82 F) unless otherwise labelled.

6 Optimal storage isat the lower half of this temperature range. To preventcontamination of unused Product , do not return any material toits original container.
