What properties should be tested for pure acrylic emulsion?
Pure acrylic emulsion is a water-based polymer coating, which is composed of methyl methacrylate (MMA) and butyl acrylate (BA) and other monomers, and is an environmentally friendly coating without volatile organic solvents. Pure acrylic emulsion has excellent water resistance, weather resistance, scratch resistance and good adhesion, and has a good gloss and flatness. Pure acrylic emulsion is widely used in indoor and external wall coating, floor coating, metal surface anti-corrosion coating, plastic surface coating and other fields, is a stable performance, convenient construction, environmental protection and health of high quality coating.
Detection performance
| Performance | test item |
|---|---|
| Solid content | The content of solids in the paint |
| Drying time | Coating drying time |
| Water resistance | Water resistance |
| Weather fastness | Uv resistance, corrosion resistance, etc |
| Adhesive force | The degree of bonding between coating and substrate |
| glossiness | Gloss of the coated surface |
| flatness | The flatness and smoothness of the coating surface |
| Scratch resistance | Scratch resistance of the coated surface |
| Colour fastness | Color fastness of the coating |
| other | Such as density, viscosity, pH value, etc |
The results of these test programs can help evaluate the quality and suitability of pure acrylic emulsions and how well they perform in practical applications. Test methods and equipment vary according to the specific pure acrylic emulsion type and test items.

Detection method
The following are common test methods for pure acrylic emulsion:
Solid content: Use oven drying method, centrifugal method and other methods to test the content of solids in the paint.
Drying time: Use equipment such as a drying time tester to measure the drying time of the coating.
Water resistance: The water resistance of the coating is tested by means of water immersion, water mist, water drop, etc.
Weather resistance: The UV resistance and corrosion resistance of the coating are tested by artificial accelerated aging test or natural weather exposure.
Adhesion: The combination degree between the coating and the substrate is tested by means of grid method, stripping method, stretching method, etc.
Gloss: Use equipment such as a gloss meter to test the gloss of the coated surface.
Flatness: Test the flatness and smoothness of the coating surface using parallel plate method, optical microscope and other equipment.

Scratch resistance: The scratch resistance of the coating surface is tested by scratch test.
Color fastness: Use equipment such as a color meter to test the color difference and color fastness of the coating.
Other: According to the specific type of pure acrylic emulsion and test items, choose the appropriate test method and equipment for testing, such as measuring the density, viscosity, pH value of the coating.
North and South tide reminds you: the performance test of pure acrylic emulsion needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
