Coverage
Coverage differs depending on the surface condition:
BM TORCH G Flat Areas : 1.15m2/m2 ( Approx.) per layer with 10cm Overlaps and 15cms end laps. Average
wastages: 2-3%.
BM PRIME SBD41 Smooth Surface: 0.3-0.5 Ltr/m2 ( Approx.) will give dry film thickness of 100 microns.
Storage
The rolls must be stored vertically in a covered area. They should not be exposed to direct sunlight, UV and other sources of heat. The shelf life of the product lasts up to 12 months from the date of production. Extreme exposure to sunlight and UV may lead to deterioration of the product and may subsequently reduce its shelf life.
Heath And Safety
When torch melted the membranes can form a sticky compound and can stick to human skin. Apply plenty of cold water if it is in hot condition. Use soft cloth dipped in a suitable cleaner to remove the same. For deep burns, immediate medical assistance is suggested.
Supply
Nominal roll length: 1mx10m ; Nominal roll width : 1m ; Nominal thickness : 3mm, 4mm, 5mm
