728 has a shelf life of 9 months when stored at a cool and dry place in unopened containers. Once opened, containers of 728 should be sealed tightly again and the product should be consumed within a short period.
When using 728 an efficient exhaust hood should be installed to the coating unit due to safety reasons. The exhaust efficiency must be checked prior to production by gas analysis for air isocyanate concentration. Safety regulations with regard to handling of isocyanates have to be followed as per the guidelines issued by the International Isocyanates Institute. Please also refer to the local safety instructions as well as our safety data sheet and contact Huitian for analytical support.
As the adhesive contains polyisocyanates any contact with skin has to be removed.
Film additives-particularly the types and content of slip agent in LDPE,MDPE and CPP films, film thickness, packed goods, printing inks, pre-treatment and film coating are of significant importance to the end use of the laminates and may affect the performance properties either directly or indirectly. Therefore, practical laminating tests as well as checks on the laminates are necessary before going into full scale production.
