Detail Company Introduction
Dear Sir,
This is Sara from Sino-expansion Co., Ltd. Here I’d like to introduce our product CRACKAG to you.
We are one of the largest manufacturers and exporters of expansive cement in China. CRACKAG is a kind of expansive chemical product, which is widely used in marble and granite quarrying, concrete demolition. Pls refer to the pictures attched.
When it is mixed with clean and cold water to be mortar and poured into pre-drilling holes of rock and concrete, it swells and exerts expansive capabilities on the hole-wall at a unit value of more than 50Mpa (500kg/cm2 .) which is strong enough to cut and crack reinforced concrete, marble and granite after a while. For more tech or other info, pls don’t hesitate to contact us.
I am hoping to set up a long term business relationship with your company for mutual benefit.
Await your early reply.
Best regards.
Sara
