Description
TACKWHITE WT 13 is an ultraremovable acrylic waterborne pressure sensitive adhesive, based on microspheric polymers in water dispersion, modified with additives and wetting agents in order to have a very good wettability on any surface combined with a clean and long lasting removability.
Application
TACKWHITE WT 13 is suitable for the production of removable and repositionable washi (paper) tapes and removable labels (made with paper, PVC, PE, PP or PET). It can be direct or transfer coated by rotogravure or Mayer bar.

Handling
TACKWHITE WT 13 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 values higher than 8.5 with ammonium hydroxide solution, if necessary. If the pH of the adhesive falls below 8.8 coagulation may occur. To pump the adhesive, air operated diaphragm pumps are recommended. Avoid the use of high speed centrifugal or gear pumps.
The recommended coat weight range is 15-20 g (dry)/m².
Packaging
The product is supplied in iron drums (200 kg); IBC containers (1000 kg).
Storing
TACKWHITE WT 13 must be stored at temperatures between +5°C and +40°C, avoiding freezing conditions.
Keep containers closed to maintain proper pH. The product tends to separate, stir well before use.
Use within 6 months from production date (unopened and in the original packaging).
