MAXTOP CRF corrosion resistant chains have excellent performance in corrosive environments.
CRF chain is based on carbon steel chain with CRF coating treatment to achieve good anti-rust performance.
The coating film has silver metallic look. Layers of metallic silver film are aligned with one another through the use of a binder, zinc and aluminum flakes.
| Features
1.No harm to the environment and health
Water-based chemical solution: Using aqueous liquid, the coating is not solvent-base; the surface treatment is friendly to both natural and working environments.
Completely chromium-free: Chromium compound is not used in the processing for CRF coating.
No Toxic Metal – Free of nickel, cadmium, lead, barium and mercury. It completely meets the requirement of RoHS, ELV and REACH regulations.
Closed system coating process: CRF coating is environmentally friendly; the main waste disposal of this coating is the steam and do not include any toxic substances regulated by law.
2.No concern for hydrogen embrittlement
CRF coating film and the coating process are not in contact with substances that could cause hydrogen embrittlement.
3.Superb resistance to high and low temperature
CRF film is able to withstand high and low temperatures for an extended period of time – within the temperature range of the chains from -30°C ~ 250°C(-22°F ~ 482°F).
The allowable load may decrease when the temperature is below -10°C or above 150°C depend on the chain sizes.
4.600 hours corrosion protection during salt spray test
CRF coating provides an outstanding corrosion resistance during the salt spray test (the test is based on ASTM B117 testing standard). Below is the test result after 600 hours salt spray test.
