Handling
TACKWHITE AMC 61 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 in open coating pans 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. 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, but it can vary accordingly to the desired final properties.
Packaging
The product is supplied in iron drums (200 kg); IBC containers (1000 kg).
Storing
TACKWHITE AMC 61 B 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).
