Graco 313289s Changing Materials, Keep Components a and B Separate

Overview

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.

Follow these recommendations for reassembly and setup:

•use at least a 3/8 in. (10 mm) x 25 ft. (7 m) 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 wetted 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. See Flush on page 14.

•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 on page 14.
