Gel-Tac® 619R2

For use in applications that require the properties of low to medium tack and clean removability.

Designed for direct coating onto various substrates by conventional coating methods such as Flexo or Mayer rod. This product should be applied at amounts of 7 – 11 lbs. (dry)/3000 sq. ft. (11.4 – 18 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. 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.

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.

For best performance, the product should be stored and used at 65 – 85°F. Do not freeze. Keep containers closed to maintain proper pH.
