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%.

Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and producing polyaspartic polyurea resin and other new chemical products. We are recognized as a "National Special New Key Little Giant" and a "State-level High-tech Enterprise", with more than 50 polyaspartic polyurea invention patents. We also participated in the preparation of 13 industry standards for polyaspartic polyurea materials as a leading company in this field, ranking No.1 in the Chinese market.

In the coating industry, polyaspartic polyurea is used in construction machinery, automobile, containers, fan blades, marine heavy corrosion protection, and high-end industrial and commercial floor coatings. In the adhesive field, it is mainly used in sealants, stone adhesives, electronic adhesives, film circuit packaging adhesives, and other high-end applications. In the waterproofing materials sector, it is primarily used in hydroelectric dams, water parks, building waterproofing repair materials, and other areas. In the structural materials field, it is applied to curling tracks, artificial ice skating rinks, and other structural materials.

Polyaspartic polyurea is considered a high-end new material in the strategy of manufacturing power. We have broken the foreign technology monopoly and filled the domestic market gap. Due to its comprehensive characteristics of "Environmental protection, Energy saving, and Long durability", polyaspartic polyurea can contribute to the realization of genuine carbon neutrality in the coatings, adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied overseas. It has been widely used to replace Bayer's current polyaspartic system in many coating companies and has been applied in anti-corrosion and waterproofing by international coating companies.
