Note: Subject to separate discussions, users'''' specific requirements can be met.
(1).The site should be kept clean. Dust and grease should be avoided as they might adversely affect product''s adhesive and electric performance.
(2).Ambient temperature should be controlled at around (25±5). Temperatures lower than that will affect levelness; while temperatures higher than that may cause back-sticking and dust can easily stick, which eventually undermine the final quality of work-pieces.
(3).Recommended curing temperature is (150±2) for 3 hours baking or (130±2) 5 hour in oven. If conditions allow, certain pressure should be applied during curing so as to promote mechanical properties effectively.
(4).This product is valid for 6 months under 25. Please use it during this period.
