Surface Preparation
The surface must be clean and free of contaminants that will inhibit the cure of SEMICOSIL® 268 Black.
Examples of contaminants are sulfur containing materials, plasticizers, urethanes, amine containing materials and organometallic compounds, especially organotin compounds.
If a substrate’s ability to inhibit cure is unknown, a small scale test should be run to determine compatibility.
储存
SEMICOSIL® 268 Black has a shelf life of 6 months from the packaging date when stored between -40°C and -20°C in the originally sealed container. The “Expiration Date” of each batch appears on the product label.
No more than 14 days with temperature from 0 ˚C to 25 ˚C is allowed for long-distance shipping.
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.
