Product Application

Designed for direct coating onto paper substrates by conventional coating methods such as flexo or mayer rod. Peel values of 2 - 4 oz/inch are typically realized in the recommended coat weight range of 4 - 8 pounds (dry)/3000 sq. ft. (6 - 13 grams (dry)/sq. meter). This product shows optimal performance on paper substrates with intermediate Sheffield smoothness values. Some substrates may require priming or additional deposition of adhesive.

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 9.5 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 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.
