Environmental Performance Testing of Polyaspartic - Polyaspartic Encyclopedias

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:

1. VOC emission only 1/6 of water-based coatings.
2. Construction waste gas toxicity 20 times lower than OSHA limits.
3. Achieves top three global green certifications (Blue Angel/A+/GREENGUARD).
4. 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%.
