Features
- aliphatic main chain structure resistant to UV degradation, outdoor tan, 10 annual preservation > 90%, non-yellow, non-frying, non-fragmentation, no additional layer of protection required to work directly on epoxy or polyurethane surfaces, and both very strong (adhesion ≥3.0 MPa), with no rise, no drop, no empty drums, suitable for long-term exterior protection of the exterior wall, combined decorative and corrosion protection, against suntan and atmospheric erosion
- Solids content ≥95%, low VOC, non-smuggling, non-toxic, non-hazardous, non-hazardous gas releases during construction and use, which can be used directly in hospitals, schools, homes, industrial buildings, etc., in sites with high environmental requirements, no hazardous residues after construction and safe environment
- Oxygen, salt-spray support, industrial atmospheric corrosion, polyaspartic polyurea topcoat, 3～5 of epoxy resin, polyaspartic polyurea topcoat after covering the surface of epoxy, polyurethane topcoat, can be combined to further enhance overall tolerance, grinding, currosion protecing, resistance to wind erosion, industrial dust pollution, acid erosion, etc. in different scenarios, and reduce the cost of future maintenance
Applications
Directly covered in epoxy or polyurethane paints, interior walls, outer walls, epcoat priority for substrates, polyurethane topcoat fittings, polyaspartic polyurea topcoat protection
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.
