Features
- The aliphatic backbone resists UV degradation, with color retention >90% after 10 years of outdoor exposure. It does not yellow, chalk or crack and needs no additional protective layer. Suitable for exposed roofs, exterior walls and coated steel roofing, particularly long-term exterior-wall protection against sun and rain.
- elongation at break ultra 300% capable of stretching, deforming and covering hair cracks following outside walls; The three-dimensional network structure is self-healing, so as to eliminate leakage from the outer wall from its roots and adapt to the micromorphic needs of different parts of the outer wall
- No membranes, no sutures, water pressure tolerance up to 0.6 MPa, waterproofing on the outer wall floor and local water harvesting scenes, closed water test 72 h zero leakage, effective containment of rainwater into the walls
- Solids content ≥95%, low VOC, non-smuggling, non-toxic, non-hazardous gas releases during construction and use, which can be used directly in the outer walls of buildings, including hospitals, schools, houses, etc., and in sites with high environmental requirements
- Oxygen, salt-spray emission, industrial atmospheric corrosive, grinding properties are 3～5 times epoxy resin, service life 20～25, far beyond traditional polyurethane, asphalt, resistant to long-term wind and rain erosion, industrial dust pollution, etc., and reducing later maintenance costs
- It also has non-floating features, suitable for construction on the outer wall, is not easy to fall and can be decorated to match the needs of all types of building exterior wall decorations and integrate waterproofness with decorations
Applications
Waterproofing of exterior walls, exterior repair, exterior protection of industrial buildings, waterproofing of new energy buildings
Storage
This product is combustible and shall be kept at low temperatures and at a temperature of ≤40℃, which requires storage in a cool, dry and ventilated environment for a period of one year, far from the source of the fire.
