Functional materials

未标题-1.jpg

DESCRIPTION

GK-8A, comprised of a variety of polymers, is an efficient concrete curing agent with stronger permeability and film-forming property. When spraying on the concrete surface, it can permeate into concrete and react with cement hydrates to form a hard and compact film, which can insulate the concrete surface from air to prevent concrete moisture lost and to achieve the effect of water-conserving and curing.

USES：GK-8A concrete curing agent is not only suitable for large area concrete curing such as highway, airport, dam and port, but also for curing the industry and civil building and structure.

CHARACTERISTICS

GK-8A offers the following advantages:

* Excellent water retention performance,

* Continuous film forming, and no perforation,

* Providing water insoluble performance,

* Good heat resistance, and no deformation,

* High compressive strength development,

* No negative effect on dry shrinkage.

APPLICATION

RECOMMEND DOSAGE

1 kg for 4m2—6m2

USING METHOD	GK-8A can be used for curing of fresh concrete, as well as demolded concrete, and continuing curing after early wet curing. It requires one time horizontal coating. If it is uneven, twice is preferred. For vertical or incline, after the first uniform coating, the surface should be transparent or semi-transparent for 40-60 minutes, and then apply the second coating.
NOTES ON APPLICATION	1. It should be used above 5C. 2. It cannot be used in combination with other curing agents. 3. After spraying, please clean nozzle and spay pipe with water for avoiding blockage. 4. The film can sustain a long-term performance and will fall off by itself in roughly half a year.
