Elastomeric coating is a kind of coating with high elasticity and strong flexibility. Its main components are polymer resin, filler, solvent, etc. It has good waterproof, durability, anti-ultraviolet and other properties. Elastomeric coatings are suitable for roofs, walls, and floors of various buildings. They can effectively prevent water leakage, cracks, etc., and can also play a role in heat insulation and noise reduction. They are widely used in residential buildings, industrial facilities, and public buildings.

Detection method
The following are the corresponding detection steps:
Film thickness:
scratch a straight line on the coating surface;
The film thickness of the coating was measured using a Film Thickness Gauge.
Adhesion:
scratch a straight line on the coating surface;
Use an adhesion Tester to measure the adhesion of the coated surface.
Water resistance:
scratch a straight line on the coating surface;
Place the coating sample in the water circulation test box to carry out the water circulation test;
Observe the changes in the coating sample, such as peeling off, discoloration, etc.
Weather resistance:
Place the coating sample in the light aging test box to carry out the light aging test;
Observe the changes in the coating sample, such as color changes, surface cracks, etc.
Wear resistance:
Place the coated sample in the abrasion Tester;
A wear test was performed to observe the wear of the coated samples.
Bending properties:
Place the coated sample in the bend Tester;
Bend tests were performed to observe the deformation of the coated samples.
Elongation at break:
Coated samples were tested using an elongation at break Tester;
The elongation at break of the coated samples under tension was measured.
For each test, the specific steps will be different, and you need to refer to the corresponding test standards or methods. Commonly used standards or methods include: ASTM, ISO, GB/T, etc. During the detection process, attention should be paid to the accuracy and repeatability of the instrument, as well as the source and storage method of the sample.
