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 corrosion protection of buried, elevated and exposed pipelines, particularly oil, chemical, water-supply and drainage pipes exposed to sunlight, rain, soil attack and corrosive media.
- Elongation at break exceeds 300%, accommodating thermal expansion, contraction and minor pipe deformation while bridging fine cracks at joints and surfaces. A dense three-dimensional network blocks moisture, oxygen and corrosive media to prevent rust and corrosion, accommodating deformation in steel and concrete pipes.
- Non-suture membrane, impenetrable water pressure up to 0.6 MPa, resistant to internal pressure of pipes and external soil pressure, closed water test 72 h zero seepage, effective barrier to external moisture, soil corrosive material infiltration to the surface of pipes, avoidance of piping damage, leakage of media
- Solids content ≥95%, low VOC, non-odour-free, non-toxic, non-hazardous gas releases during construction and use, direct use in pipelines such as drinking water pipes, chemical and gas pipelines, suitable drinking water delivery, food-grade media, etc.
- Oxygen, salt-spray fusion, corrosive resistance to various industrial media (oil, acid solutions), grinding properties are 3～5 times the epoxy resin, service life 20～25 years, far beyond traditional corrosion protection coatings, which are resistant to long-term problems of piping such as soil corrosion, media flushing, industrial atmospheric erosion, and reduce pipe maintenance and replacement costs
- Appearances can be transmuted, depending on the use of pipelines and environmental needs, to integrate corrosion protection with marking, and to balance protective and recognition
Applications
Construction of drainage and fire pipes for water protection and repair; Oil and gas pipelines, chemical pipelines, heat pipelines, pipelines sealed;
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.
