ZHENGDA Curing Agent

ZHENGDA Curing Agent is an efficient concrete curing agent, which is widely used in construction, road, bridge and other engineering fields. It is made of high-quality raw materials and has the characteristics of efficient curing, strong durability and convenient construction.

The main component of the curing agent is polyamide ester resin, which can quickly react with the cement in the concrete to form a high-strength chemical bond, making the concrete more robust and durable. In the construction process, only need to apply the curing agent to the concrete surface, and then mechanical polishing or grinding, you can achieve the ideal effect.

ZHENGDA curing agent can not only improve the strength and durability of concrete, but also effectively prevent the phenomenon of sand formation and powder drop on the surface of concrete. At the same time, it can also play a waterproof, dustproof, oil and other functions, making the concrete surface easy to clean and maintain.

The curing agent is suitable for all types of concrete surfaces, including newly poured concrete, old concrete restoration, industrial floors, etc. Not only that, it can also be used indoors and outdoors, adapting to a variety of environmental and climatic conditions.

In short, ZHENGDA curing agent is an efficient and reliable concrete curing agent, which has been widely used in construction, roads, Bridges and other engineering fields, and has become the preferred product for concrete surface treatment.
