In a recent blog, we discussed JB water-based adhesives’ uses and advantages. JB adhesives are a line of water-based pressure sensitive adhesives. They can be used for a variety of applications including tape, label, masking and specialty packaging. Let’s take a closer look at considerations to make when applying JB adhesives:
Typical Drying Considerations
Typical drying equipment for JB adhesives is zoned convection ovens. In most applications, the first zone is set to a lower temperature to prevent adhesive skinning. Then, the temperature is increased in subsequent zones to complete drying.
It is important to note:
- Oven and dwell time must be customized for each application.
Press Side Additives
Aziridines are commonly used as cross linkers. This will increase cohesive strength and deaden the tack to make a product more removable.
It is also recommended that the following items be added:
- Defoamer should be added to unformulated products and can be added in small amounts to some formulated products to optimize runnability.
- Surfactant can also be added to improve wet out when applying the adhesive to low surface energy substrates.
