AQUADEX 4213 offers excellent tray life and consistent performance across varying production conditions, making it a dependable choice for envelope manufacturers.
The high bond strength creates a secure seal that provides tamper-evident properties, giving end users confidence in the integrity of their mail. Once activated and sealed, the adhesive forms a strong bond that tears the paper substrate rather than releasing cleanly, providing clear visual evidence of any tampering attempts.
Fast drying characteristics mean envelopes move through the production line quickly without risk of blocking or offsetting. This allows manufacturers to maintain high throughput speeds whilst minimising downtime for cleaning and maintenance, directly impacting productivity and operational costs.
The formulation reactivates easily with controlled moisture application, providing consistent seal quality across the entire production run. This reliability reduces waste from failed seals and maintains quality standards that meet customer expectations for professional envelope products.
AQUADEX 4213 is a dextrin-based remoistenable adhesive formulated for envelope flap gumming applications. The adhesive responds well to standard moisture reactivation methods, whether applied by the end user with a sponge or roller, or through automated envelope sealing equipment. Its blocking resistance characteristics make it suitable for both individually produced envelopes and high-volume manufacturing where envelopes are stacked immediately after production. The formulation has been developed to work across different paper substrates commonly used in envelope manufacturing, from standard offset papers through to recycled and speciality stocks.

As with all industrial adhesives, appropriate handling procedures should be followed. Wear suitable protective equipment including gloves and eye protection during application. Work in well-ventilated areas and avoid prolonged skin contact. Consult the product Safety Data Sheet for complete safety information, first aid measures, and disposal guidance. Keep containers tightly closed when not in use and store away from sources of heat or ignition.
Apply AQUADEX 4213 at ambient temperatures using standard roller or spray gumming equipment. The adhesive should be stored in sealed containers. Stir well before use to maintain consistency. For optimal performance, maintain application equipment cleanliness and follow regular cleaning schedules to prevent build-up.
