Procedure

1.Paint Preparation: Dilute the original paint with 10% water (by volume).

2.Spray Application on Substrate: Using the same substrate, apply the paint with a spray gun using the following pattern:

Horizontal passes: 6 passes.

Vertical passes: 4 passes (over the same wet area, creating a heavy film build).

3.Multi-Round Evaluation (3 Rounds):

Round 1: Spray 2 overlapping cross-coats (one horizontal + one vertical pass set).

Round 2: Spray 3 overlapping cross-coats.

Round 3: Spray 4 overlapping cross-coats.

4.Fluid Adjustment Between Rounds: After completing each round, increase the fluid delivery (material output) of the spray gun by approximately half a turn.

5.Constant Parameters During Each Round: Within each round, do not adjust the fluid flow rate, air pressure, or atomization settings of the spray gun.

Purpose: This method evaluates the paint's sag resistance under increasing film thickness and material output, simulating potential application errors or heavy builds.

Conclusion

Anjeka 4420 demonstrates superior application characteristics in spray operations:

Excellent Atomization: Provides finer mist and reduced overspray compared to other thixotropes at equivalent viscosity.

Smooth Application: Results in a quieter spray process with less paint mist.

Enhanced Metallic Effect: Promotes superior aluminum flake orientation and alignment.

Balanced Performance: Maintains good sag resistance without negatively affecting gloss or recoatability.

High-Gloss Finish: Achieves gloss values of up to 121 GU (at 60°) and 75 GU (at 20°).
