High-solids coatings are coatings with high solid content and relative molecular weight, often abbreviated as HSC (High-Solids Coating). These coatings typically have a solid content of 65%, 85%, or even higher. The most environmentally friendly high-solids coatings are solvent-free. High-solids coatings are widely used in industries such as light manufacturing, handicrafts, textiles, electromechanical equipment, instrumentation, and engineering machinery coatings.

In the diverse market of grout sealants, distinguishing between polyurea and epoxy variants can be challenging. Here are some insights from Feiyang: Before Application: Experienced users can differentiate by scent; polyurea emits a milder and more characteristic odor compared to epoxy. Using pH test strips to check the alkalinity of Component A can provide useful information. Alkaline readings typically indicate polyurea, while non-alkaline readings suggest other types of sealants. Mixing a known epoxy B component with the B component of the sealant under evaluation can reveal polyurea; if a heat-generating, gel-forming reaction occurs, it indicates polyurea.

The main ingredient in epoxy sealants is epoxy resin, and the combined content of the A and B components in the sealant formula exceeds 50%. Given that epoxy resin is the primary component, discoloration is inevitable and is only a matter of time. The materials contain chromophoric groups, such as the aromatic ether and benzene ring structures in epoxy resins, as well as the conjugated double bonds in unsaturated resins. These structures can form colored substances when exposed to UV radiation or oxygen oxidation, leading to yellowing and powdering of the material.

Polyurea flooring enhances the strengths of epoxy flooring, improving both its physical and construction properties. Unique in design and customizable in color, polyurea flooring offers excellent wear resistance, non-slip surfaces, and vehicular traffic endurance, making it easy to clean. This makes it highly suitable for use in industries such as the oil industry, chemical plants, electronics, pharmaceuticals, food, machinery, and offices. Specifically, polyaspartic polyurea, representing the third generation of polyurea products, outperforms standard polyurea flooring in wear and scratch resistance, weather durability, color stability, and crack resistance, even in outdoor settings. Its simple, efficient, and rapid application makes it an optimal choice for high-end, solvent-free flooring solutions.

High-content solid, low-viscosity refers to a material with high solid content and low viscosity. Polyaspartic resin is a typical example of this kind of material. High solid content means fewer volatile substances in the material, resulting in lower VOC (Volatile Organic Compounds) emissions, which contributes to the creation of environmentally friendly products. Low viscosity enhances the workability of the material, facilitating easier application. Additionally, resins with lower viscosity require fewer diluents, further reducing VOC emissions.

Cold storage units are categorized into low-temperature, medium-temperature, high-temperature, quick-freeze, and controlled atmosphere types. The primary market is low-temperature storage, accounting for 72%, primarily used for food storage at -18 to -25°C, which is ideal for preserving meat and vaccines. The unique environment of cold storage units demands high-quality flooring materials that can withstand prolonged low temperatures and endure the impact and pressure of forklifts during loading and unloading. Therefore, the materials must exhibit excellent low-temperature resistance and impact durability.
