Application and use
42Rpo is a removable, coloured pressure-sensitive adhesive with very high opacity. It shows good initial adhesion and, due to the innovative double-layer technology, very good removability on most surfaces - even after a longer application time.
Due to its balanced adhesive properties, the removable pressure sensitive adhesive is ideally suited for a wide range of applications. Due to its very high opacity, 42Rpo is usually used for opaque covering of information that should still be accessible afterwards (e.g. addresses, previous barcode and many more).
However, the low adhesion of 42Rpo is likely to be insufficient for applications on curved surfaces. The adhesive is resistant to light, heat and ageing.
Processing
Excellent die-cutting characteristics on all customary machines.
Storage conditions and shelf life
Storing at a temperature of 20 ± 5 °C, a relative humidity of 45 ± 5 % and a dark storage is recommended. Moisture, heat and direct sunlight have to be avoided.
Regulations concerning contact with food
The pressure-sensitive adhesive 42Rpo can be safely used for the back coating of labels for the labelling of foodstuffs for storage at room temperature and below. It may be used in direct contact with dry, moist and fatty foodstuffs that can be assigned a correction factor of at least 4 in accordance with Regulation (EU) No. 10/2011.
