Pure acrylic emulsion is a water-based polymer coating, which is copolymerized from monomers such as methyl methacrylate (MMA) and butyl acrylate (BA). It is an environmentally friendly coating that does not contain volatile organic solvents. Pure acrylic emulsion has excellent water resistance, weather resistance, scratch resistance and good adhesion, as well as good gloss and smoothness. Pure acrylic emulsion is widely used in indoor and outdoor wall coating, floor coating, metal surface anti-corrosion coating, plastic surface coating and other fields. It is a high-quality coating with stable performance, convenient construction, environmental protection and health.
Detection performance
| performance | Test items |
|---|---|
| solid content | Solids content of paint |
| drying time | coating drying time |
| water resistance | Water resistance |
| weather resistance | UV resistance, corrosion resistance, etc. |
| Adhesion | The degree of bonding between the coating and the substrate |
| Gloss | Gloss of the coating surface |
| Flatness | Flatness and smoothness of the coating surface |
| Scratch resistance | Scratch resistance of the coated surface |
| Color fastness | Color fastness of the coating |

The results of these test items can help evaluate the quality and applicability of pure acrylic emulsion, and how it will perform in practical applications. The test methods and equipment vary according to the specific type of pure acrylic emulsion and the test items.
Detection method
The following are common detection methods for pure acrylic emulsion:
Solid content: Use oven drying method, centrifugation method and other methods to test the solid content in the coating.
Drying time: Use a device such as a drying time Tester to measure how long it takes for the coating to dry.
Water resistance: test the water resistance of the coating by water immersion, water mist, water droplets and other methods.
Weather resistance: test the UV resistance and corrosion resistance of the coating through artificial accelerated aging test or natural climate exposure.
Adhesion: The degree of bonding between the coating and the substrate is tested by cross-hatch method, peeling method, tensile method and other methods.
Gloss: Use a gloss meter and other equipment to test the gloss of the coating surface.
Flatness: Use parallel plate method, optical microscope and other equipment to test the flatness and smoothness of the coating surface.
Scratch resistance: Test the scratch resistance of the coating surface by scratch test.
Color fastness: Use color difference meter and other equipment to test the color difference and color fastness of the coating.
Others: According to the specific type of pure acrylic emulsion and testing items, select the appropriate testing method and equipment for testing, such as measuring the density, viscosity, pH value of the paint, etc.
NBCHAO 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.
