Application Instructions

This adhesive 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 9.0 - 9.5 with ammonium hydroxide solution, if necessary. If the pH of the adhesive falls below 8.0, coagulation may occur.
Air operated diaphragm pumps are recommended to pump the adhesive. Avoid the use of high-speed centrifugal pumps.

Cleaning Instructions

The adhesive will clean up with water and mild soap when wet; dried material may require clean up with a solvent such as acetone or ethyl acetate.

Typical Applications

Designed for transfer coating onto vinyl substrates.
This product can be coated onto release liner using conventional coating methods such as reverse roll and Mayer rod.
