●Use complete equipment for spraying, which can be applied on site, fast curing and high production efficiency.

●According to the use requirements, various pigments and fillers can be added to make coatings with different colors and functions.

Construction Introduction

●Substrate processing (special primer for coating)

Because the curing speed of sprayed polyurea elastomer is extremely fast, the requirements for substrate treatment are strict.

1. The surface of the base should be compacted and flat, and there should be no looseness, sand, or peeling; garbage and debris must be cleaned; the base should be kept dry before construction, and construction should be in accordance with the construction specifications and design requirements.

2. Repair existing defects on the substrate surface. For different substrates, corresponding supporting materials can be used to repair surface holes, cracks and other defects, and make the necessary preparations for forming a smooth, smooth, and beautiful coating.

3. In order to improve the adhesion and shear strength of the coating film and the base layer, the special surface can be shot blasted, sandblasted, and sanded.

4. After the treatment of key parts is completed, a high-permeability primer must be applied to the surface of the base. In order to ensure the matching and compatibility of the coating and the substrate.

●Spraying

The spraying construction shall be carried out according to the construction process and scheme designed according to the actual site conditions. For special-shaped structures and weak locations, pre-enhanced spraying should be carried out. The overall construction of the spraying should be completed within 4H as much as possible. If it exceeds 4H, the reinforcement layer should be polished, brushed or sprayed with an interlayer standing mixture, and the polyurea coating should be applied after 20 minutes. When applying polyurea coating, ensure that the coating is uniform. Before construction, the slag and debris on the substrate must be cleaned up before construction.

Storage and transportation

Unused raw materials should be stored in well-sealed barrels to avoid moisture intrusion and affect raw material quality. The ideal raw material storage temperature is 25 ± 5 ℃. The storage period is 6 months.
