The environmental performance of polyaspartic is its core advantage over traditional solvent-based coatings, particularly suitable for sensitive environments such as food factories, hospitals, and schools. The systematic environmental testing framework and certification details are as follows:
Core Environmental Indicator Test Methods
1. VOC (Volatile Organic Compounds)
Testing Standards: GB 38507-2020 (water-based coatings), ISO 11890-2 (Headspace Gas Chromatography)
polyaspartic characteristics: 100% solids content formulation, actual VOC ≤5g/L (National standard limit 50g/L)
Testing Procedure:
2. Hazardous Substance Limit Testing
Biological Safety and Ecotoxicity Testing
1. Acute Oral Toxicity (OECD 423)
Method: Rats administered 5000mg/kg dose orally and observed for 14 days
Result: LD₅₀ >5000mg/kg (practically non-toxic)
2. Aquatic Toxicity (ISO 6341)
Test organism: Daphnia magna (water flea)
EC₅₀ (48h): >100mg/L (non-toxic; epoxy resin EC₅₀≈20mg/L)
Environmental Verification During Application
1. Construction Waste Gas Analysis (EPA Method 25A)
Field Sampling: Gas collected 0.5m from spray area
Key Data:
2. Solid Waste Leaching Toxicity (GB 5085.3)
Method: Detection of heavy metal leachate from waste residue
Result: Lead/Cadmium/Chromium leachate <0.1mg/L (far below hazardous waste limit of 5mg/L)
Long-term Environmental Performance Verification
1. Harmful Substance Release After Aging (LEED v4.1)
Procedure:
1.QUV aging for 4000h
2.TVOC emission tested according to CDPH Standard V1.2
Result: TVOC <50μg/m³ (LEED Gold requirement ≤500μg/m³)
2. Drinking Water Contact Safety (GB/T 17219)
Immersion test: Coating immersed in 40°C deionized water for 30 days
Testing items:
Authoritative Environmental Certification Systems
1. Global Mainstream Certifications
2. Additional Certifications for Special Scenarios
Food Contact: FDA 21 CFR 175.300
Children's Toys: EN 71-3 (Heavy metal migration)
Medical Devices: ISO 10993 (Biocompatibility)
Environmental Comparison with Traditional Materials
Technologies for Enhancing Environmental Performance
1. Bio-based Raw Material Substitution
Castor oil-modified polyether: Bio-carbon content ≥30%, CO₂ emissions reduced by 40%
Performance balance: Hardness reduced by 10%, chemical resistance unchanged
2. Nano-photocatalytic Coating
Titanium dioxide addition: VOC self-decomposition (formaldehyde purification rate 92%)
Side-effect control: Additive ≤3% to prevent chalking
Summary: Three-dimensional Environmental Performance Verification System
Engineering Value
Polyaspartic achieves comprehensive environmental protection from production to disposal through molecular design (100% solids content), clean technology, and biodegradable modification:
- VOC emission only 1/6 of water-based coatings.
- Construction waste gas toxicity 20 times lower than OSHA limits.
- Achieves top three global green certifications (Blue Angel/A+/GREENGUARD).
- Biodegradation rate exceeds national standard (GB/T 19277) by 150%.
Note: Verify third-party test reports (focus: TVOC emission, heavy metals, acute toxicity). Prioritize innovative formulations with bio-based content >20%.
