Q: Functionality and durability

Based on our current knowledge, the following functionality and durability of 3M™ Thermoscript foils can be expected. Generally, not less than the following times with vertical outdoor weathering, provided the foils have been properly processed and applied according to 3M recommendations: Durability Outdoor use: 2-3 years Indoor use: virtually unlimited Shelf life 2 years Recommended storage condition 23°C / 50% relative humidity. It is recommended to store the film/label rolls in polyethylene bags.

Q: Processing

Die-cutting Sharp knives and minimal web tension are recommended, to avoid possible adhesive squeeze-out. Substrate pretreatment / Bonding See processing information KG-054
