Why Can Polyaspartic Polyurea Be Hand-Brushed?

Most of us have heard of polyurea materials. However, the majority of them are sprayed-on polyureas, which require specialized spraying equipment for application. So, what's different about Polyaspartic Polyurea? Why can it be hand-brushed?

The difference lies in their structural composition. Spray-on polyurea is an elastomeric substance formed by the reaction of isocyanate components (often referred to as Component A) with amine compounds (commonly known as Component R). The chemical reaction between these two components is incredibly swift, gelling in 5 seconds and achieving walk-on strength in just a minute. If applied manually, the material would have completed its reaction even before the application process begins. Therefore, it necessitates the use of professional equipment and must be applied under high temperature and pressure conditions.

On the other hand, Polyaspartic Polyurea is the result of the reaction between secondary amine groups on the polyaspartic ester resin and isocyanates, forming a resin that contains urea bonds. Its reaction speed is slower than that of the sprayed polyurea, allowing for a longer application window. It isn't limited to two-component spray equipment and can be conveniently applied using methods like air spray, airless spray, manual brushing, and roll coating, making it more versatile.

As an industrialized high-performance resin material, Polyaspartic Polyurea has a wide range of applications. It primarily serves as the main resin for coatings, used in waterproof coatings, anti-corrosion coatings, floor coatings, industrial coatings, and more. Additionally, it can be used in seam sealants, grouting adhesives, bonding agents, casting materials, and the development of new applications continues.

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.
