rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>For safe handling information on this product, consult the Material Safety Data Sheet (MSDS).<\/strong><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Directions For Use<\/strong><\/p>\n<p>1. For best performance bond surfaces should be clean and free from grease.<\/p>\n<p>2. To ensure a fast and reliable cure, <strong>EF<\/strong> <strong>Activator 56 <\/strong>should be applied to one of the bond surfaces and the adhesive to the other surface. Parts should be assembled within 15 minutes.<\/p>\n<p>3. The recommended bondline gap is 0.1mm. Where bond gaps are large (up to a maximum of 0.5 mm), or faster cure speed is required, <strong>EF<\/strong> <strong>Activator 56 <\/strong>should be applied to both surfaces. Parts should be assembled immediately (within 1 minute).<\/p>\n<p>4. Excess adhesive can be wiped away with organic solvent.<\/p>\n<p>5. Bond should be held clamped until adhesive has fixtured.<\/p>\n<p>6. Product should be allowed to develop full strength before subjecting to any service loads (typically 24 to 72 hours after assembly, depending on bond gap, materials and ambient conditions).<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Storage<\/strong><\/p>\n<p><strong>ReAct<\/strong> <strong>727 <\/strong>should be stored in a cool, dry location in unopened containers at a temperature between 46\u00baF to 82\u00baF (8\u00baC to 28\u00baC) unless otherwise labeled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused material, do not return any material to its original container.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Dispensing Equipment<\/strong><\/p>\n<p><strong>Hernon<\/strong> offers a complete line of semi and fully automated dispensing equipment.
