Waterborne polyurethane system
Product Details
Product features
Hydration system, almost odorless;
The coating has a smooth and flat appearance with good decorative properties.
The gloss of high-gloss polyurethane after lamination can reach 70-90 (high gloss)
For top use: 50-70 (for matte top use)
The gloss of matte polyurethane after lamination is ≤ 30.
This product has strong adhesion to various substrates and is not prone to peeling or falling off. It is not prone to yellowing, can enhance surface wear resistance and has a long service life. Anti-mold and antibacterial, it can be used in the pharmaceutical, food and other industries.
Scope of application
It is particularly suitable for floors that need to be kept highly clean and
In places where the construction odor is required to be low, such as hospitals, food factories,
Supermarkets, dairy factories, light industrial plants, warehouses, exhibition halls, schools, etc.

Notes
Strictly control the construction temperature between 10℃ and 30℃, and the relative humidity between 20% and 80%. Construction is prohibited when the ground is damp.
The polyurethane varnish can only be applied after the coating is completely dry; otherwise, there will be problems such as shrinkage and inability to apply.
After the topcoat layer dries, it should be promptly varnished. If left for too long, the surface is prone to contamination, and after varnishing, particles or even delamination may occur.
Water-based polyurethane can only be topcoat on the epoxy material or other materials recommended by our company. When topcoat on other external surface layers, there may be problems such as oil shrinkage and unresolved bubbles. If it is directly applied on inorganic floors, there is a risk of delamination and peeling.
When in use, first mix components A and C, stir evenly, and then add Component B. The addition sequence must be strictly followed.
When applying waterborne polyurethane by roller coating for topcoat, a short and medium-bristled roller should be used, and the coating should be applied in two coats horizontally and vertically to ensure even coating without any omissions.
Waterborne polyurethane dries relatively quickly. During construction, pay attention to controlling the joint marks, which should not exceed 10 minutes.
Water-based polyurethane matte products are less dirt-resistant compared to glossy ones. Once they get dirty, they must be cleaned promptly. Factories and garages should be cautious when choosing them.

Construction section

Construction conditions
Air temperature: 10℃ - 30℃
Relative humidity: 20% - 80%
Dew point temperature: The substrate and the substrate of the uncured coating must be at least 3℃ higher than the dew point temperature to reduce the risk of condensation or mottling of the ground coating.
Oily floors must be thoroughly cleaned up; otherwise, it may affect the even application of the coating.
