RP45 (sales code)
Water washable permanent adhesive.
Acrylic, water borne.
Should be used in applications where labels need to be water-washable. Best washability is obtained with hot alkaline water, but RP 45 is also washable with pure hot water. The required washing time depends on the labelled surface, time after applications and the washing conditions.

RP 45 is recommended especially for labelling of plastic substrates, like plastic boxes and containers in logistics and retail applications. Other labelling substrates should be tested carefully prior to application. Water absorption properties of the face paper will strongly influence the washability properties. Printing ink and method will also greatly influence the wash-off time. There is a risk that the wash-off properties may be reduced if labels are stored in humid conditions or under UV exposure (such as outdoor conditions) for long periods of time. Wash-off properties should be tested beforehand with printed labels.
The raw materials conform to FDA 21CFR 175.105 (indirect food contact).
From the date of manufacture one year in +20°C and RH 50%, with Thermal Eco face material 6 months.
