The full name of the product "Polyaspartic" is "Polyaspartic Ester Polyurea". It comprises two components, A and B. Component A is polyaspartic ester resin, and Component B is isocyanate curing agent. These components are individually sealed and packaged, mixed uniformly on-site in a specific ratio, exhibit low viscosity, and cure rapidly.

Introduction to Polyaspartic

Polyaspartic ester is a new type of aliphatic, slow-reacting, high-performance coating material in the polyurea industry, known as the third generation of polyurea. It is a novel two-component, relatively slow-curing, highly weather-resistant polyurea material. This technology has nearly 15 years of application history in European and American markets and 7 years in the Chinese market. The chemical reaction principle of polyaspartic ester polyurea:

Evolution of Polyurethane Reaction Types

Reaction Activity: Hydroxyl group < Secondary amine group < Primary amine group

Polyaspartic successfully addresses issues associated with spray polyurea systems such as overly rapid reaction rates leading to difficulty in control, poor adhesion, and dependence on large equipment. It also overcomes the shortcomings of traditional polyurethane coatings, including inability to cure at low temperatures, sensitivity to humidity, and the need for baking equipment for curing.

Product Composition

Component A: Polyaspartic resin

The structure of polyaspartic resin, containing secondary amine groups. Its reactivity and physical properties vary according to changes in X and R.

Component B: Isocyanates (HDI trimer/IPDI, HMDI prepolymer)

The HDI trimer series, due to its aliphatic properties and cyclic structure, exhibits:

• Exceptional UV resistance and weatherability (non-yellowing with excellent gloss retention)
• Chemical and solvent resistance
• Excellent appearance

The HDI trimer polyisocyanate, with its high transparency and very light color, is ideal for producing attractive and durable polyurethane varnishes and topcoats.

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.
