Description
TACKWHITE AMC 20 is a ultra-removable p.s. adhesive, based on acrylic microspheric polymers in water, properly modified with additives and wetting agents which produce a very good wettability combined with a very constant and clean removability.
Application
TACKWHITE AMC 20 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. It can also be applied by transfer coating, in this case it is necessary to use a suitable primer.

Handling
TACKWHITE AMC 20 may separate over time: this is typical for this type of adhesive. Mix before use: adhesive will readily redisperse with mild agitation. Check pH in open coating pans and adjust to 9 with ammonium hydroxide 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 15-20 g dry/m², according to paper porosity.
Storing
TACKWHITE AMC 20 must be stored at temperatures between +5°C and +40°C, avoiding freezing conditions.
