Sag Resistance Tester Paint Flow Test 50-675μm Gradient 25μm

Product Features & Attributes
This sag resistance tester is used to determine the sagging performance of paints during application and drying on vertical surfaces. It rapidly evaluates product quality and determines optimal paint application thickness, saving time and application costs. Suitable for paint formulation adjustment and application thickness control, not applicable to varnishes and powder coatings.

Working Principle: Apply paint evenly onto a glass panel with multi-groove film thickness gradients (50~675μm, 25μm gradient). Place vertically under standard conditions to dry. Observe sagging at each groove position to determine the maximum film thickness without sagging, evaluating paint sag performance and optimal application thickness.

Structural Features:

• Tool steel construction, corrosion resistant, easy to clean

• Compact and well-designed structure

• Attractive appearance, simple operation

• High precision control, excellent performance

Technical Parameters:

• Glass panel size: 200×120×(2~3)mm

• Film thickness range: 50~675μm

• Thickness gradient: 25μm

Test Procedure:

1. Apply paint evenly across grooves on the glass panel

2. Place panel vertically, dry under standard conditions

3. Observe sagging at each groove position

4. Determine maximum film thickness without sagging

5. Evaluate paint sag performance and optimal application thickness

Precautions:

• Clean and dry after each use

• Only trained personnel may operate

• Do not leave during testing

• Store in clean, non-corrosive room temperature environment

• Read manual carefully before use

Maintenance:

• Clean promptly after each use

• Store in dry place when not in use

• Avoid contact with corrosive substances

Available in different specifications: different film thickness ranges (50-675μm, 50-1000μm, etc.), different thickness gradients (25μm, 50μm, etc.), and different panel sizes to suit various paint types and testing standards.

Mainly used in paint manufacturers, coating contractors, automotive coating industry, quality inspection institutions, research universities, and more for paint sag resistance and optimal application thickness testing.
