 Application Adding Method

Generally speaking, COST-1266 is used to seal the crack by indirect heating with the FO oil. 

Operation steps:


Use the suitable tools to clean the crack, remove any dust, oil, grease, print and other contaminants, and keep the crack clean and dry.

1. Hot melt the sealing paste, the heating temperature of the product is about 180°C-


Usually, we hot melt the sealing paste by indirect heating with FO oil, instead of directly heating and suddenly heating. 

Before heating, put it into heating container (drum) first, step heat up, the heating time is decided by entirely melting of sealing paste.


2.For better appearance, cover the outside of the joint areas with Ninon film or paper, lest cause contamination when sealing.


3. Let it cool down before pouring and sealing. The best pouring temperature is about 



4. Remove the Ninon film after finishing, keep the surface neat.

We suggest using COST style heating equipment. This equipment has good quality 

and can be operated easily. It helps improving the construction quality, and developing good work environment. 

Ending the pouring work, traffic can be opened in time immediately. 







Shelf Life

It can be kept for 5 years.




Keep away from fire. Storage temperature too high, the packaging will deform, but no affect 

its use.

Avoid to contact fire. No smoking during construction.

If splash on clothes or skin, please flush with water immediately, or ask for doctor.
