7035 powder coating: With excellent mechanical properties, how to resist outdoor physical impact?

Update:13 Feb,2025

Pencil hardness is a common method to measure the hardness of coatings. It determines the hardness level of coatings by scratching the surface of coatings with pencil leads of different hardness. 7035 powder coatings performed well in pencil hardness tests, and its hardness level is much higher than that of ordinary coatings, which means that it can better resist scratches and wear.

In practical applications, the hardness of coatings is directly related to their service life and aesthetics. Natural factors such as wind, sand, rain, and sunlight in outdoor environments, as well as artificial friction and scratches, may damage the coating. The high hardness of 7035 powder coatings enables it to maintain the integrity and aesthetics of the coating under these harsh conditions. Even if exposed to outdoor environments for a long time, the coating is not prone to scratches, wear, etc., thereby extending the service life of the coating.

In addition to pencil hardness, impact strength is also one of the important indicators for measuring the mechanical properties of coatings. It reflects the ability of the coating to maintain the integrity of the coating when it is impacted by external forces. 7035 powder coating also performs well in impact strength. Its excellent impact resistance enables it to withstand various physical impacts in outdoor environments, such as human damage, natural falling objects, etc.

In outdoor environments, the coating may be subjected to impact forces from different directions, such as bird strikes, branch scratches, and human kicks. These impact forces often cause serious damage to the coating and even cause the coating to fall off. The high impact strength of 7035 powder coating enables it to maintain the integrity of the coating under these impact forces, thereby avoiding the occurrence of coating shedding and cracking.

The reason why 7035 powder coating can perform well in mechanical properties is mainly due to its unique formula and advanced production process. The coating uses high-quality polyester resin as the main film-forming material, and adds an appropriate amount of fillers, additives and pigments. Through precise proportioning and mixing, a coating system with excellent mechanical properties is formed.

In terms of production technology, 7035 powder coating uses advanced electrostatic spraying technology and high-temperature baking curing technology. Electrostatic spraying technology enables the coating to be evenly attached to the surface of the substrate to form a dense coating. The high-temperature baking and curing process enables the resin molecules in the coating to fully cross-link and cure, forming a coating structure with high strength and hardness.

In practical applications, 7035 powder coatings have shown excellent mechanical properties and weather resistance. Whether in the fields of building curtain walls, transportation facilities, household appliances or automotive accessories, the coating can provide a durable and beautiful protective layer. Especially in outdoor environments, the high hardness and high impact strength of 7035 powder coatings enable it to effectively resist the erosion of natural factors such as wind, sand, rain, and sunlight, as well as damage caused by artificial friction and scratches.

For example, in the field of building curtain walls, 7035 powder coatings are widely used in the coating of various metal sheets and aluminum alloy profiles. These materials are easily eroded by natural factors such as wind, sand, and rain in outdoor environments, and the high hardness and high impact strength of 7035 powder coatings enable it to effectively protect these materials from damage, thereby extending the service life of building curtain walls.
