Performance of butyl sealant
Clean and dry adhesion surface to get rid of dirty, oily things. Lfz28 is applied by special hot-melt butyl extrusion machine. The extrusion condition could be satisfied through temperature and pressure adjustment, for example temperature could be adjusted over the range of 120¡ãc~150¡ãc. The environment temperature should not be lower 10¡ãc in application.
Package of butyl sealant
Lfz28 butyl sealant for insulating glass primary seal, black, 1kg/paper pail, 5kg/pail, 7kg/pail or supply according to customer required.
