|Thickness (mm)||1.6 ± 0.1%|
|Weight (kg / m³)||1.45 ± 0.1%|
|Loss factor DIN EN ISO 6721-3: D200 Hz at 20°C||0.050|
|Thermal stability DIN 52 123 ( °C)||Vertical application: 80 °C/24h ≤ 1 mm, 100 °C/ 2h ≤ 1 mm
Over-head: 100 °C
|Adhesive strength at 20°C (N/cm)||10 min adhesion ≥ 7
24 h adhesion ≥ 10
|Burning behavior DIN 4102||B 2|
Gives a light stiffening effect on thin sheet metal, water resistant.
The surface must be carefully cleaned from dust, grease, oil and water. Full area adhesion has to be insured. The adhesion strength is directly dependent from the processing pressure.
The material has to be pressed in firmly, e.g. using a feed roll.
Processing temperature: 18 – 25 °C
Dry at temperatures between 18 – 35 °C
Max. storage time: 6 months
Standard sheet size
1000 x 1000 mm
Specific formats and cut-outs on demand.
