Crack Sealant

We are offering crack sealant.
product overview
reey series crack sealants are economical and durable high-elasticity-polymer. They are applied to asphalt pavement irregular cracks, cement pavement work joints, cracks treatment before composite pavement construction, airport pavement joints, special roads, and roads of wharfs etc.
reey series sealants have unique characteristics including waterproof, caking property, elastic-plastic, high temperature stability, low-temperature flexibility, durability and anti-embedding. Under natural changes of the climatic conditions and repeated vehicle axle load, they can achieve longer road performance without early aging.

characteristics:
1. Waterproof
crack sealant couldn’t be dissolved by water and couldn’t imbibe water. It could stop water’s infiltration.
2. Caking property
crack sealant has strong cohesion with the road surface even when the road is thermal expansion or cold contraction. It couldn’t be dissolved by water and couldn’t imbibe water but could stop infiltration of water.
3. Elasticity
crack sealant has good flexibility. Its amount of stretch meets the crack and joint requirements of transfiguration. It could extend and contract along with road surface without snapping.
4. Stability with high temperature
crack sealant could stay toughness in summer without becoming liquid to pollute the road and affect the traffic.
5. Flexibility with low temperature
crack sealant could stay flexible in winter low temperature without rigidification and brittle crack.
6. Set-in resistance
crack sealant could resist sundries such as sands or stones setting in road and guarantee the flex of joints on road surface.
7. Hot-melting characteristics
crack sealant is a kind of hot-melting material. It could be heat up time after time when using. The left material in crack sealing machine could be used again by heating without cleaning out.
