|
Bitumen
|
✓ Good penetration into the surface due to its fluidity |
✗ Its protectiveness can be affected by polymer grade |
| ✓ When used in pavements, it improves the sticking between different layers and increases the resistance to deformation |
✗ It is affected by the temperature in the summer season by making the coating soft |
| ✓ High water resistance |
✗ Difficult to apply to plastic surfaces |
| ✓ High resistance to mechanical damage |
✗ Overheat buildings when it is used to the roof |
| ✓ High resistance to UV radiation |
|
|
Acrylics
|
✓ Highly resistant to variations in temperature |
✗ Complex removal procedure |
| ✓ High impact resistance |
✗ Fast drying |
| ✓ High chemical resistance |
✗ Poor water repellent |
| ✓ User friendly, easy to apply |
✗ Low UV radiation resistance |
| ✓ High fungus resistance |
|
| ✓ Lower cost applications |
|
| ✓ Good adhesion properties |
|
|
Polyurethane resin
|
✓ High performance in its mechanical properties such as flexibility, strength, hardness, and stiffness |
✗ It is sensitive to humidity |
| ✓ Control concrete carbonation |
✗ Delays the natural breathing capability of concrete |
| ✓ Long service life |
✗ Low weathering resistance |
| ✓ High resistance to UV radiation |
✗ Strong toxic fumes |
| ✓ Economic maintenance |
✗ Less alkali-resistant than epoxy coating |
| ✓ High hardness and impact resistance |
✗ High cost |
