Anti-corrosion Coating FAQ
Q: How long does anti-corrosion coating typically last?
A: Our high-performance anti-corrosion coating systems provide protection for 10-15 years in standard industrial environments and 7-10 years in marine conditions when properly applied and maintained. The actual service life depends on environmental factors, surface preparation quality, and maintenance practices.
Q: Can anti-corrosion coating be applied over existing paint?
A: While possible in some cases, we recommend complete removal of existing coatings for optimal performance. If overcoating is necessary, conduct adhesion testing and ensure compatibility. The surface must be thoroughly cleaned and profiled (minimum 25 microns profile) for proper bonding of the new anti-corrosion coating.

Additional Anti-corrosion Coating FAQ
Q: What are the safety precautions when applying anti-corrosion coating?
A: Always use proper PPE including respirators with organic vapor cartridges, chemical-resistant gloves, and protective clothing. Ensure adequate ventilation in confined spaces. The product contains isocyanates (in the curing agent) - avoid skin contact and inhalation of vapors. Refer to the SDS for complete safety information and first aid measures.
