Gel-Tac® 619ND

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

• 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 - 14 lbs. (dry)/3000 sq. ft. (18 - 23 g (dry)/sq. meter) for the purposes of initial evaluation.

• 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.

For best performance, the product should be stored and used at 65 - 85°F. Do not freeze. Personnel should wear gloves and splash goggles when handling material. Keep containers closed to maintain proper pH.
