Bottom Coating FAQ Section
What substrates are suitable for Bottom Coating application?
Our Bottom Coating formulations are engineered for use on carbon steel, stainless steel, concrete, and certain thermoset plastics. For best results, surfaces must be properly prepared according to SSPC-SP10 standards, with all contaminants removed and an appropriate surface profile achieved. We offer specialized primers for problematic substrates that require enhanced adhesion.
How does Bottom Coating compare to traditional epoxy coatings?
Bottom Coating represents a significant advancement over conventional epoxy systems. While standard epoxies typically offer 5-7 years of protection in harsh environments, our Bottom Coating formulations provide 12-15 years of service life. The proprietary chemistry provides 30% greater abrasion resistance and superior flexibility, reducing cracking and delamination issues common with traditional coatings.
Performance Comparison Data
| Test Method | Bottom Coating | Standard Epoxy |
|---|---|---|
| ASTM D4541 (Pull-off Adhesion) | 3,750 psi | 2,100 psi |
| ASTM G65 (Abrasion Resistance) | 35 mg loss | 150 mg loss |
| ASTM B117 (Salt Spray) | 5,000 hours | 2,000 hours |
Bottom Coating Maintenance Guidelines
- Annual Inspection: Check for any signs of mechanical damage or coating degradation
- Cleaning: Use pH-neutral cleaners only - avoid strong solvents
- Touch-up Protocol: Repair damaged areas within 24 hours of identification
- Recoating Interval: 12-15 years under normal service conditions
What safety precautions are required when applying Bottom Coating?
All Bottom Coating applications require OSHA-compliant PPE including NIOSH-approved respirators with organic vapor cartridges, chemical-resistant gloves (butyl rubber recommended), and protective eyewear. Maintain adequate ventilation with a minimum of 4 air changes per hour in enclosed spaces. Our formulations contain less than 100g/L VOC, but proper respiratory protection remains essential during spray application.
