What are the Ingredients in Polyurea and Polyaspartic Polyurea?

What is the composition of polyurea?

Polyurea is an elastomeric material made by the reaction of isocyanate component (referred to as A component) and amino compound (referred to as B component), which is a new type of non-polluting, solvent-free, high-performance green coatings containing repeated urea groups in the molecular structure. Through the efforts of experts for decades, aromatic polyurea, aliphatic polyurea, polyaspartic polyurea and other polyurea with different molecular structures have been put into use in major fields.

The more widely used spray polyurea elastomer (SPUA) combines the reactive properties of polyurea with the rapid molding properties of reaction injection molded polyurethane (RIM), can be a variety of large-scale equipment or complex surfaces surface treatment, but its operation requires professionals equipped with special spraying equipment.

What is the composition of polyaspartic polyurea?

Polyaspartic polyurea is an aliphatic, slow-reacting, high-performance material that has gained attention due to its excellent overall performance, adjustable reaction time, and good outdoor weatherability of polyaspartic polyurea topcoats.

Polyaspartic polyurea is composed of two components, and hexamethylene diisocyanate (HDI) trimer and polyaspartic ester were used in the early stage, but the synthesized polyaspartic polyurea showed poor performance in mechanical properties and complex microstructure. Afterwards, polyaspartic polyureas were produced by first reacting aliphatic isocyanates with end-amino polyethers to obtain prepolymers or semipre-polymers, and then reacting with amino components.

A series of polyaspartic derivatives with different strengths, gel times and properties can be obtained by selecting different primary diamine compounds to react with maleates, and the tensile strength and elongation of the polyaspartic polyurea materials obtained by reacting different kinds of polyaspartic with HDI trimers with 20.5%-21.5%-NCO content are also varied greatly.

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.
