Consultation & Requirement Analysis

Initiate a conversation with us, whether it's through our website or email. We'll delve deeply into discussing your coating needs. Every detail of each project is crucial, and we ensure that we provide the optimal coating solution that meets all your specifications. Here are the core areas we consider during our requirement analysis:

Expected appearance color and gloss level

Guidelines for Appearance Requirements

1.Physical Samples: Examples include already-coated parts, plastic or aluminum pieces.

2. Color Card Code: PANTONE, RAL, or other international color standards. E.g., "RAL(D2.E2.K7)".

3. Image/Digital Reference: While not the first choice, it can sometimes serve as a reference. Be mindful of screen and printing variations.

4. Color Description: Such as "Deep Ocean Blue" or other specific color names.

5. Color Variation: Given the potential differences in color due to various substrates and coatings, please specify your acceptable range of variation.

6. Desired Gloss Level: Options include high gloss, semi-gloss, satin, or matte. If possible, provide a specific GU range.

Substrate and Product Applications

Guidelines for Providing Your Substrate and Application Information:

1.Metals: Clearly specify the type of metal you are using, such as aluminum, iron, copper, aluminum alloy, zinc alloy, or aluminum-magnesium alloy, among others.

2.Plastics: Indicate the specific type of plastic, like ABS, PC, ABS+PC, PP, PA nylon, etc.

3.Rubber: Describe the kind of rubber material you are working with.

4.Carbon Fiber: Provide detailed information about your carbon fiber composite to ensure we offer the most suitable coating.

5.Wood: Whether it's hardwood or softwood, specify the type of wood to assist us in selecting the optimal coating for you.

6.Other Substrates: If your material type isn't listed above, please provide a detailed description or relevant information.

7.Product Applications: Clarify the kind or purpose of the product where you intend the coating to be applied, such as automotive industry (e.g., wheel rims) or bicycles (e.g., frames).

Expected Physical Testing Requirements

Provide Your Performance Requirement Guidelines:

1. Adhesion: Please specify if tests such as peel-off or cross-hatch are required.

2. Hardness: Indicate whether pencil hardness or Rockwell hardness tests are needed.

3. Abrasion Resistance: Specify if the coating needs to resist wear from friction or rubbing.

4. Gloss Level: Let us know if a specific glossometer reading is desired.

5. Drying Time: State any required drying period post-application./

6. Flexibility: Indicate if impact or bending tests are necessary.

7. Environmental Resistance: Describe if tests for UV resistance, salt fog resistance, or high humidity resistance are required.

8. Chemical Resistance: Specify if the coating needs to resist solvents, acids, or alcohols.

9. Water Resistance: Inform us if the coating should withstand water immersion or repulsion.

10.Temperature Tolerance: Specify if the coating must endure high or low temperatures.

11. Film Thickness: Indicate if a specific dry film thickness is necessary.

12. Color Matching: Let us know if the coating's color should align with a specific standard or sample.

13. Anti-Yellowing: State if the coating must resist yellowing under prolonged light exposure.

14. Additional Performance Requirements: If you have any other specific coating performance or testing requirements not listed above, please specify. We will do our best to accommodate and provide you with the relevant data and support.

Production Factor Requirements

Provide Your Production Requirement Guidelines

1.Coating Type: Specific categories such as water-based, powder, oil-based, etc.

2.Order Quantity/Coating Volume: Please specify the estimated order quantity or the total amount of coating required.

3.Baking Requirements: Please specify whether low temperature, high temperature, or other specific temperature baking is needed, or if baking is not required at all.

4.Curing and Drying: If not baked, state if the coating should be left at room temperature for 24 hours or any specified period.

5.Packaging Time: Time required to package the product post curing or drying.

6.Quality Inspection: Standards and procedures for quality and qualification inspection after product completion.

7.Product Labeling: Ensure clear and accurate labeling for each product, providing all necessary information such as product name, batch number, instructions for use, safety information, etc.

8.Storage Conditions: Specify appropriate storage conditions like temperature and humidity control to ensure the stability of the coating.

9.Transportation: Consider the mode and conditions of transportation to ensure product performance and stability during transit.

10.Safety and Environmental Considerations: Ensure all production and packaging activities comply with local safety and environmental regulations.

11.International Delivery: If the product is sold overseas, provide related export standards and requirements.

12.Additional Production Requirements: If you have any other specific production needs or special requirements, please elaborate in detail.
