A and B Components

Changing Materials

•When changing materials, flush the equipment mul- tiple times to ensure it is thoroughly clean.

•Always clean the fluid inlet strainers after flushing.

•Check with your material manufacturer for chemical compatibility.

•Most materials use ISO on the A side, but some use ISO on the B side.

•Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the B (resin) side.

A and B Components

IMPORTANT!

Material suppliers can vary in how they refer to plural component materials.

Be aware that when standing in front of the manifold on proportioner:

•Component A (Red) is on the left side.

•Component B (Blue) is on the right side.

For all machines:

•The A (Red) side is intended for ISO, hardeners, and catalysts.

•If one of the materials being used is moisture-sensi- tive, that material should always be in the A (Red) side.

•The B (blue) side is intended for polyols, resins, and bases.

NOTE: For ratios higher than 1:1, the higher volume is typically the B (Blue) side.
