What is Truly Eco-friendly Coating?
Eco-friendly coatings are products that meet performance and safety standards while adhering to the technical criteria for environmentally certified products.
Types of Eco-friendly Coatings
The main types of eco-friendly coatings are as follows:
- UV-curing coatings
- Powder coatings
- Water-based coatings
- Conventional high solid content coatings
- Polyaspartic polyurea coatings
How to Choose Eco-friendly Coatings?
1. UV-Curing Coatings
- Advantages include rapid curing, high efficiency, energy savings, and being solvent-free.
- Disadvantages include a strong odor and the toxicity of volatile monomers. It also requires specialized equipment and is unsuitable for complex workpieces or thick, colored coatings.
- Application Areas: Mostly used in wood coatings, crafts, and advertising packaging, with significant industrial application limitations.
2. Powder Coatings
- Advantages include being solvent-free, odorless, and recyclable, with excellent production line efficiency and corrosion resistance.
- Disadvantages include the need for complex equipment and processes, high energy consumption, and limited suitability for complex or non-metal workpieces.
- Application Areas: Industrial anti-corrosion fields, replacing some high-solid or solvent-free coatings in heavy anti-corrosion applications.
3. Water-based Coatings
- Advantages include being water-dilutable and offering enhanced safety for users and the environment.
- Disadvantages include high requirements for substrates and environmental conditions, as well as the need for wastewater and waste treatment. Certain applications also demand high energy consumption for baking.
- Application Areas: Building, furniture, and some light industrial anti-corrosion fields.
4. Conventional High Solid Content Coatings
- Advantages include reduced cost and lower VOC emissions.
- Disadvantages include slow drying, high application viscosity, limited suitability for thin coatings, and high hardness and brittleness.
- Application Areas: Mainly used in heavy anti-corrosion fields.
5. Polyaspartic Coatings
- Advantages include low VOC emissions, fast drying, high efficiency, suitability for solvent-free thick or thin coatings, curing at ultra-low temperatures, and excellent tensile and mechanical performance.
- Disadvantages primarily involve high material costs, leading to increased product pricing.
- Application Areas: Widely used in industrial anti-corrosion, adhesives, waterproofing, flooring, and increasingly favored in high-end markets.
Polyaspartic coatings demonstrate superior overall performance among eco-friendly coatings.
These coatings offer significant environmental advantages, including no need for wastewater treatment and substantial energy savings for large workpieces. They are also temperature-insensitive, allowing for all-season application. Additional benefits include reduced labor costs due to thick coatings, exceptional weather and temperature resistance, as well as outstanding wear and impact resistance.
