Applications & Uses

Application Method
Compatible Substrates & Surfaces
Typical Applications
  • Designed for transfer coating onto paper substrates.
  • This product can be coated onto release liner using conventional coating methods such as Reverse roll and Extrusion systems.
  • It should be applied at amounts of 10-13 lbs. (dry)/3000 sq. f t. (16-21 grams (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 9.9 with ammonium hydroxide solution, if necessary. If the pH of the adhesive falls below 8.5, 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.
