Applications & Uses

Product Application

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. It should be applied at amounts of 11 – 13.5 lbs. (dry)/3000 sq. ft. (18 – 22 g (dry)/sq. meter) for the purposes of initial evaluation.

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.
