Sprayed Polyurea vs. Hand-Applied Polyurea: Which Performs Better?

Polyurea, dubbed the "greatest invention in the coatings industry" and one of the most promising high-tech materials of the 21st century, is a familiar term to many. Commonly, polyurea is categorized into hand-applied and sprayed types. But what distinguishes these two?

Sprayed polyurea is further divided into aromatic and aliphatic types. Aromatic sprayed polyurea, the first-generation, is now complemented by aliphatic sprayed polyurea, the second-generation, offering improved mechanical properties and aging resistance with reduced reactive activity. Sprayed polyurea, comprising Components A and B, cures rapidly (about 10 seconds), thus requiring large-scale spray equipment.

Features of Sprayed Polyurea:

1. Quick reaction, suitable for any surface, including curves, without sagging.
2. Excellent stability, minimally affected by environmental factors.
3. Superior physical properties, achieving desired thickness in one application.

Drawbacks of Sprayed Polyurea:

1. Complex application process, requiring professional operation.
2. Contains toxic elements, demanding strict protective measures.
3. Ideal for large projects, challenging for precise local applications, with potential contamination in non-sprayed areas.
4. Moderate weather resistance and adhesion.

Hand-applied polyurea, primarily polyaspartic polyurea, represents the third-generation. This innovative dual-component, slow-reacting (relative to sprayed polyurea) material boasts high weather resistance. Polyaspartic polyurea ingeniously modifies the reactive groups of traditional polyurea, simplifying application and broadening its use.

Characteristics of Polyaspartic Polyurea:

1. Adjustable activation time (ranging from minutes to hours), easy application through various methods like brushing, spraying, or rolling.
2. Low odor, high solids content, and low VOC emissions, environmentally friendly, energy-efficient, and does not require baking.
3. Excellent overall performance, withstanding weather, wear, and aging, capable of curing at low temperatures.

For different scenarios, both sprayed and hand-applied polyurea have their merits. The choice depends on the specific performance requirements of the application.

Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and producing polyaspartic polyurea resin and other new chemical products. We are recognized as a "National Special New Key Little Giant" and a "State-level High-tech Enterprise", with more than 50 polyaspartic polyurea invention patents. We also participated in the preparation of 13 industry standards for polyaspartic polyurea materials as a leading company in this field, ranking No.1 in the Chinese market.

In the coating industry, polyaspartic polyurea is used in construction machinery, automobile, containers, fan blades, marine heavy corrosion protection, and high-end industrial and commercial floor coatings. In the adhesive field, it is mainly used in sealants, stone adhesives, electronic adhesives, film circuit packaging adhesives, and other high-end applications. In the waterproofing materials sector, it is primarily used in hydroelectric dams, water parks, building waterproofing repair materials, and other areas. In the structural materials field, it is applied to curling tracks, artificial ice skating rinks, and other structural materials.

Polyaspartic polyurea is considered a high-end new material in the strategy of manufacturing power. We have broken the foreign technology monopoly and filled the domestic market gap. Due to its comprehensive characteristics of "Environmental protection, Energy saving, and Long durability", polyaspartic polyurea can contribute to the realization of genuine carbon neutrality in the coatings, adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied overseas. It has been widely used to replace Bayer's current polyaspartic system in many coating companies and has been applied in anti-corrosion and waterproofing by international coating companies.
