In the coatings industry, film hiding power is one of the key indicators to measure the performance of coatings. Hiding power not only affects the appearance quality of the coating, but is also directly related to construction efficiency and cost control. With the rapid development of the coating industry, the demand for the detection of paint film hiding power is increasing, especially in meeting international standards and improving product quality, high-precision testing equipment is particularly important.

Technical features:
The measurement accuracy of the measuring instrument is within 0.3%, which ensures the accuracy and reliability of the measurement results. Its spectral sensitivity is similar to the spectral power distribution of CIE standard light source C, which can accurately measure the intensity of reflected light, and is suitable for a wide range of colors and materials.
The instrument is small in size, simple in structure and easy to use. The digital display is precise and reliable, even in the case of large fluctuations in grid voltage, with minimal impact on the measurement results.
The paint film hiding force Tester has good stability and can be used continuously for a long time, which is suitable for a variety of application scenarios in laboratories and industrial sites.
In addition to measuring the hiding power of paint films and the tinting strength of pigments, the instrument can also be used in other areas where reflectivity needs to be measured, such as plastics, paper, textiles, etc.
Composition and working principle
host
The use of advanced new electronic devices, such as DC regulated power supply, DC amplifier, digital watch movement and adjustment knob, etc., to ensure the stability and reliability of the instrument.
Probes and accessories
It is composed of a light source, a lens, an optical filter, a ring selenium cell, etc., and is accompanied by a set of calibration standard plates and two sets of working standard plates for calibration and measurement.
Paint Film Applicator
Three wet Film Applicators are included to prepare standard coat films to ensure accurate measurements.
How it works
Based on the photoelectric integration technology, the hiding power of the paint film is evaluated by measuring the intensity of the reflected light. The spectral sensitivity of the instrument matches the spectral power distribution of the CIE standard light source C, enabling accurate measurement of reflectance.
Market application
Coatings industry——Paint film masking Tester is widely used in quality control and product development in the coating industry. By accurately measuring the hiding power of paint films, companies can optimize coating formulations, improve product quality, and reduce production costs.
Pigment Tests –The instrument can also be used for pigment tinting strength testing, helping pigment manufacturers to evaluate the performance of products and ensure the effectiveness of pigments in different applications.
Other areas –In addition to the coatings and pigments industry, paint film hiding force Testers can also be used in other areas where reflectance needs to be measured, such as plastics, paper, textiles, etc.
Test Method:
Sample preparation
Place a small amount of BPA epoxy in a 50 ml beaker and add a small amount of acetone to dissolve. A small amount of sample is dipped in a small glass rod and coated on the sodium bromide crystal plate to form a thin film.
Measurement process
Place the prepared sample on a sample holder and scan it using an infrared Spectrophotometer . On the resulting infrared spectrum, the reflectance is measured by plotting tangent lines from peaks and valleys around 1700 cm⁻¹.
data analysis
Based on the epoxy values and absorption ratios of the known samples, the standard operating curve equation was obtained using the least squares linear regression method to accurately assess the hiding power of the sample.
