Product Description
Sag Index Applicators
This applicator allows the sag resistance of coating to be visually evaluated. It applies a series of 10 parallel tracks of the coating to the substrate.
Each adjacent track is thicker than the last. This test panel is then held vertically. The sag index value is determined as being the first track which does not sag into the one below (with the thickest at the bottom). The step interval between each track indicates a sag of 25%.
Now conforming to new International Standard BS / ISO 16862

Precision Meets DurabilityCrafted from stainless steel, our sag index applicator offers reliability and longevity with 0.01 mm gap accuracy. The integrated handle design enhances stability, while the satin/matte finish reduces glare during measurement. Multiple gap heights allow for highly accurate and consistent sag resistance testing, making it the preferred choice for professionals in the paint industry.
Designed for Easy MaintenanceAfter each use, cleaning the applicator is essential to prevent residue accumulation. Its polished surfaces make maintenance swift and efficient, ensuring that precise results are achieved every time. A simple manual cleaning procedure preserves calibration integrity for consistent performance in R&D and quality testing applications.
FAQs of Sag Index Applicators:
Q: How is the Sag Index Applicator used in paint sag resistance measurement?
A: To measure sag resistance, apply the paint onto a substrate using the applicators precise gap heights, then observe sag behavior. The tools accuracy ensures reproducible results crucial for paint formulation and quality control.
Q: What benefits does the satin/matte surface finish offer during testing?
A: The satin/matte finish reduces glare, providing clearer visibility when applying and measuring paint patterns, which improves accuracy and comfort for the operator in laboratory environments.
Q: Where can this applicator be used, and for which types of testing is it ideal?
A: It is best used in R&D labs and quality control departments within the paint and coatings industry, supporting ASTM D4400 and ISO 16862 compliance in sag index testing procedures.
Q: What is the recommended cleaning process for maintaining the applicator?
A: Clean the applicator manually after each use with suitable solvents to remove paint residue, ensuring gap heights remain precise and free of buildup. Dry thoroughly before storing.
Q: What are the maximum substrate and measurement ranges for this applicator?
A: The tool accommodates substrates up to 2 mm thick and a measurement range approximately between 75 m and 300 m, depending on the model, allowing versatility in test specimens.
Q: How does integrated handle design impact usability?
A: With the handle seamlessly part of the main body, users experience enhanced grip and stability, reducing fatigue and facilitating consistent manual application for reliable testing results.
