High wet tack side seam adhesive designed for secure envelope bonding at minimal coat weights. This efficient formulation delivers paper-tearing bond strength with low maintenance requirements, making it an economical choice for volume envelope production.
The white adhesive provides good visual contrast during application and quality control checks.
The ability to achieve reliable bonds at lower coat weights directly reduces adhesive consumption per thousand envelopes. This efficiency cuts material costs without compromising the bond strength or seam security that customers expect, improving profit margins on competitive envelope products.
Paper-tearing performance provides clear evidence of proper bonding. When seams are tested, the paper substrate fails before the adhesive releases, confirming that the bond strength exceeds the internal strength of the paper itself. This characteristic gives manufacturers and customers confidence in seam reliability.
Low maintenance characteristics mean fewer production interruptions for equipment cleaning and less labour spent on maintenance activities. The adhesive runs cleanly through application systems without excessive build-up, crusting, or hardening that can interfere with precise application.
AQUAPAL 4607 is a high wet tack side seam adhesive formulated to provide maximum bonding performance at minimal application weights. High wet tack characteristics means the adhesive develops strong initial grab immediately on contact with the substrate, before significant drying has occurred. This rapid tack development allows folding operations to proceed quickly without waiting periods, supporting high-speed production cycles.

Follow standard industrial adhesive safety practices during handling and application. Wear protective gloves and safety eyewear to prevent contact with skin and eyes. Maintain good ventilation in application areas to minimise exposure to vapours and mists. Wash thoroughly with soap and water if skin contact occurs. Seek medical attention if eye contact occurs after rinsing thoroughly with water. Keep away from sources of ignition and store in cool, dry conditions. Consult the product Safety Data Sheet for comprehensive safety information, including emergency procedures and environmental considerations.
Apply AQUAPAL 4607 at room temperature using properly maintained side seam application equipment. Protect from freezing which can cause permanent separation or property changes. Mix well before use and at regular intervals during production. Clean application equipment with warm water before adhesive dries to prevent difficult residue removal.
