5 Operation
High viscosity products
Use a feed line with larger internal diameter for dispensing high viscosity products.
Instead of using a ¼" feed line, use a ⅜" feed line. Feed line Kit No. 97220, order no.
135561, is available for this purpose.
Use a larger, conical dispense needle, e.g. needle PPC18GA, ID -
(No. 97222) or PPC16GA, ID
product dispensed will be insufficient.
Separation of products
To ensure optimum adhesive strength, the product should not be allowed to separate.
Use only small containers holding the amount of product consumed during a shift or a
day to minimize separation.
Avoid angled fittings for product connections, e.g. to the dispense valve. Use straight
fittings only. Care should be taken to run the feed line properly, with a wide radius.
Thixotropic products
Prolonged idle periods will change the flow behavior of a thixotropic product due to its
chemical properties. As a result, the amount of product dispensed will be reduced. To
compensate for this phenomenon, run 2 – 3 dispense cycles before returning the system
to operation.
