Description
TACKWHITE AMC 8 B is an ultraremovable water based pressure sensitive adhesive, based on acrylic microspheric polymers properly modified with additives and wetting agents which produce a very good wettability of any surface combined with a very constant and clean removability. TACKWHITE AMC 8 B is characterized by a very low peel and tack, suitable for the production of repositionable labels for newspaper.
Application
TACKWHITE AMC 8 B is suitable for the production of removable and repositionable paper labels. It is designed for direct coating onto paper substrates by conventional coating methods such as flexo or Mayer rod.
With a suitable primer (such as PRIMER MC-K) can be also applied by transfer coating.

Handling
TACKWHITE AMC 8 B may separate over time: this is typical for this type of adhesive. Mix before use: adhesive will readily redisperse with mild agitation. Check pH and adjust to values higher than 8,5 with ammonia solution, if necessary. If the pH of the adhesive falls below 8,8 coagulation may occur. Air operated diaphragm pumps are recommended to pump adhesive. Avoid the use of high speed centrifugal pumps.
The recommended coat weight range is 10-15 g (dry)/m², according to paper porosity.
Packaging
The product is supplied in plastic pails (20 kg); plastic drums (100 kg); IBC containers (1000 kg).
Storing
TACKWHITE AMC8 B must be stored at temperature between +5°C and +40°C, avoiding freezing conditions.
Product tends to separate over time, stir slowly and for a prolonged time before use.
Use within 6 months from production date (unopened and in the original packaging).
