Comparation between Graphene Zinc & Epoxy Zinc
| Items | Epoxy zinc rich coating system | Epoxy graphene zinc coating system |
| SST | 600hrs. （HG/ 3668） | 4500hrs. |
| Moisture and heat resistance | Good | Excellent |
| Cathodic protection performance | Cathodic +barrier protection, rapid corrosion of damaged areas | Excellent cathodic+barrier protection, effectively avoid crevice corrosion and localized corrosion |
| Crevice corrosion, localized corrosion, acid corrosion | Barrier protection is dominant, and localized corrosion is serious | Good cathodic protection ability, excellent local corrosion protection performance, composite coating system can effectively solve the problem of acid rain corrosion |
| Maintenance cycle | About 5 to 7 years, local pre-treatment or poor application, rust will appear in 1 to 2 years | >15 years |
| Application property | Moderate, high requirements for pre-treatment and construction environment conditions, otherwise it is easy to crack and fall off | Easy, can be conveniently applied in the factory and on site, and the requirements for the ambient environment conditions are general requirements |
| Touch up | It must be thoroughly ground down to the steel body, making maintenance difficult | Good recoating performance, low treatment requirements before recoating |
| Cost | High procurement costs, multiple repainting and maintenance throughout the life cycle, resulting in large direct and indirect losses | Low purchase cost, long-term anti-corrosion, avoiding multiple maintenance, good corrosion adaptability, convenient application and maintenance, and low life-cycle cost |
