1. Specifications of F520

2.Properties of F520

FEISPARTIC F520 is an amino-functional co-reactant for polyisocyanates; it could be used to formulate high-solids, two-component polyurethane topcoats, and solvent-free coating materials.

FEISPARTIC F520 can also react with –NCO functional HDI trimmer from which a longer gelling time and excellent yellow resistance can be achieved. A longer gelling time can also be obtained when mixing with FEISPARTIC F420 to achieve a pure aspartic polyurea coating with a high build and a fast dry two-pack coating system. FEISPARTIC F520 is compatible with other hydroxyl-functional resins, such as acrylic and alkyd resin. It is widely applied in formulating a variety of protective coatings.

Polyaspartic ester polyurea resins react with polyisocyanates to create two-component polyurea/clear urethane coats.
Polyaspartic resins blend well with isocyanates for a more robust, more durable finish. The noted features they provide exterior coatings are weather and yellow resistance, zero VOCs (volatile organic compounds), and fewer coats that need to be applied to give more efficiency. End-users find freedom in a fast dry time, and it can be easily applied with standard equipment even though it has a high solid content. The advantages of using polyaspartic esters are the flexibility to design the reactivity to accommodate batch mixing and application, control over the cure rate when added to aliphatic coatings, and the ability to change the reaction time to extend the pot life. It can be customized to the needs of the application.

3. Storage

FEISPARTIC F520 resin must be stored in tightly sealed containers to prevent from contacting with moisture. Recommended storage temperatures are 0°-40°C (32°-104°F). The shelf life of FEISPARTIC F520 is 12 months when stored in original closed containers at 77°F (25°C).

4. Polyaspartic Property Advantage

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.
