Best cold fill sealant It's a kind of ointment. Once exposed to air, the moisture solidifies into a tough, rubbery solid material.There are several main types: deacetic type\ dealcoholization\ take off the ammonia type.Best cold fill sealant often used as concrete asphalt pavement cracks bonding and sealing.So commonly known as road sealant.
1.Product overview.
Silicone adhesive English name is silicone.It's organic silicon.
2. Basic use
Used for bonding and sealing of concrete, asphalt pavement, airport runway, glass, marble etc.
3. Features:
1.Polydimethyl siloxane, the polymer of silicon dioxide can be called silicone. A single group of silicone rubber, which is cured by contact with the moisture in the air to produce a physical change;
2.BEST silicone gel will not be extruded, physical properties change and fracture under the temperature of minus 25 to 30 degrees Celsius. Fully cured silicone rubber in the temperature to 204 ℃ (400 of) using can still remain valid, but the temperature as high as 218 ℃ (428 of), the effective time shorten, resistance to high temperature and low temperature performance is stable.
4.Packaging:
Each can be packed in 4 and 30 kg, which is easy to construct and can be filled directly in the crack after opening the slot.
5. Construction procedures:
1. Small cracks do not need to be slotted, and 1.2cm cracks are slotted at a depth of about two centimeters.
2. Clean the cracks, and dust can not be found on either side of the crack wall.
3. Crack the adhesive directly into the crack.
4. After construction, spray the surface to float sand, 2 -- 3 hours after dry, open
