QMB-II Minimum Film-Forming Temperature Tester

Applicable standards: GB/T 9267-2008 and ISO 2115-76 are used to determine the minimum film‑forming temperature of polymer emulsions. When polymer emulsions are employed as surface‑treatment agents for coatings, adhesives, synthetic fibers, leather, paper, and other materials, their film‑forming properties constitute one of the most critical characteristics. By applying a polymer emulsion or latex paint onto a metal substrate, the water evaporates, allowing the polymer particles to interact and, at an appropriate temperature, to form a continuous, transparent film. The lowest temperature at which this film‑forming process can occur is defined as the minimum film‑forming temperature of the polymer emulsion, commonly abbreviated as MFT.

QMB-II Minimum Film-Forming Temperature Tester

Description

Product Introduction

Technical Specifications:

1. The gradient plate’s operating temperature can be adjusted anywhere between -7°C and 70°C.

2. Gradient board test points: 13

3. Gradient interval: 20 mm

4. Test coating troughs: 6 units, with a length of 240 mm, a width of 22 mm (national standard: 20–25 mm), and a depth of 0.25 mm (national standard: 0.20–0.30 mm).

5. The inspection report shows: at 16:00, points 1–13 indicate the working gradient temperature, point 14 indicates the instrument ambient temperature, and points 15 and 16 indicate the inlet and outlet temperatures of the cooling water.
