Components A and B

IMPORTANT!
Material suppliers can vary in how they refer to plural
component materials.
Be aware that in this manual:
Component A refers to resin or major volume.
Component B refers to the hardener or minor volume.
NOTE:
This equipment doses the B component into the A com-
ponent flow. An integration hose must always be used
after the mix manifold and before the static mixer.
NOTE:
Please follow these recommendations for setup:
use at least a 3/8 in. (10 mm) x 25 ft. (7 m) hose as
the integration hose.
install a 24-element static mix tube after the integra-
tion hose.
Keep Components A and B Separate
NOTICE
To prevent cross-contamination of the equipment's wet-
ted parts, never interchange component A (resin) and
component B (hardener) parts.

Changing Materials

When changing materials, flush the equipment mul-
tiple times to ensure it is thoroughly clean.
Always clean the fluid inlet strainers and outlet filter
after flushing, Flush Mixed Material, page 16.
Check with your material manufacturer for chemical
compatibility.
Epoxies often have amines on the B (hardener)
side. Polyureas often have amines on the A (resin)
side.
NOTE:
If the amine will switch between the two sides, see
Flush Mixed Material, page 16.
