Automotive paint hardener recycling refers to the business of recycling, purchasing, or processing waste or by-products containing automotive paint hardeners. Automotive paint hardeners are a commonly used chemical used to cure and dry automotive paint, enhancing the coating's hardness and durability.

The process of reclaiming automotive paint hardeners typically includes the following steps:

1. Collection: Recycling companies or related organizations establish partnerships with auto repair shops, car manufacturers, and others to collect discarded automotive paint hardeners or surplus hardener materials.

2. Inspection: The reclaimed hardener will undergo quality inspection, including purity, moisture content, and impurity tests, to determine if it meets the relevant standards.

3. Classification: Categorize based on the quality and usage of the hardener, such as recyclable hardeners and non-recyclable waste.

4. Processing: Recyclable solidifiers will undergo a series of processing techniques, such as purification, filtration, and distillation, to ensure their quality and purity. Waste materials will be disposed of in an environmentally friendly manner, including chemical neutralization, incineration, landfilling, or other disposal methods.

5. Reuse: The treated binder can be reused in the production of automotive paints, coatings, etc., to achieve resource recycling.

The purpose of reclaiming automotive paint hardeners is to reduce resource waste and environmental pollution, while also enhancing resource utilization efficiency. Enterprises reclaiming hardeners must possess relevant qualifications and technology to ensure the safety and reliability of the recycling and processing process.
