In some cases these aqueous washes can affect the cure and This product is not normally recommended for use on plastics (particularly thermoplastic materials where stress cracking of 5 the plastic could result). Users are recommended to confirm compatibility of the product with such substrates. Directions for use The following tests refer to the effect of environment on For best performance surfaces should be clean and free of strength. This is not a measure of sealing performance. grease. The product is designed for close fitting flanged parts with gaps up to 0.25mm. Apply manually as a continuous bead or by screen printing to one surface of the flanges. Low Grit Blasted Mild Steel Laps pressures (<0.5bar) may be used when testing to confirm a C complete seal immediately after assembly and before curing. Flanges should be tightened as soon as possible after assembly to avoid shimming. Product shall be ideally stored in a cool, dry location in unopened containers at a temperature between 8 C to 28 C (46 F to 82 F) unless otherwise labelled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused product, do not return any material to its original container.
