Honeywell Solutions in Non-Cure Rubber Asphalt Waterproof Coatings
Release Time:
2021-09-15
Non-cured rubber asphalt waterproof coating uses rubber, asphalt and softened oil as the main components, and is mixed with temperature control agent and filler to make a waterproof coating that maintains a viscous paste state within the service life. It has self-healing properties and is suitable for construction engineering deformation. The waterproofing treatment of seams and other special parts has outstanding effects, and is widely used in non-exposed building waterproofing projects.

As Xiongan New District further clarifies the heat resistance and viscosity of non-cured rubber asphalt waterproof coatings at 130°C, it will develop towards high heat resistance and low construction temperatures. The selection of high temperature resistant modifiers is crucial to improve Softening point, lower viscosity at high temperatures, and lower use of naphthenic oils will improve the quality of non-cured rubber asphalt waterproof coatings.

| Modifier type | Performance characteristics |
| Honeywell wax | Significantly improves high temperature performance, reduces system viscosity, and lowers construction temperature at the same time. Good compatibility with asphalt, no segregation problem |
| Domestic oxidized wax | It can improve high-temperature performance, but increases viscosity, making construction inconvenient and product stability not high. |
| PP wax |
It can improve high temperature performance, but it dissolves slowly, has poor compatibility, increases viscosity, is inconvenient for construction, and reduces the bonding performance of the system. |
| Domestic polyethylene wax | Limited improvement in heat resistance |
| EBS | Limited improvement in heat resistance, easy to precipitate, affecting the appearance of the can after opening |
