DD66-05 2K Chrome-Effect Silver Coating

DD66-05 2K Chrome-Effect Silver Coating

DD66-05 is a two-component, solvent-based acrylic coating developed for automotive interior plastic parts that require a bright metallic and chrome-effect appearance. The system is designed around a chrome-effect silver resin, metallic silver pigment system and dedicated hardener. Compared with a 1K system, the 2K structure is intended to provide a more robust cured film and improved resistance potential after the complete coating system has been validated.

The coating is suitable for premium automotive interior components where metallic appearance, surface durability and process flexibility are important. It provides a coating route for customers seeking a chrome-effect finish while reducing reliance on conventional electroplating processes. Final appearance and durability depend on the substrate, primer, basecoat, silver layer, clearcoat and application conditions used together.

Core positioning: 2K chrome-effect silver coating for automotive interior plastic refinishing and component finishing.

Technical Data Sheet (TDS)

Provisional-data notice: DD66-05 does not currently have a model-specific approved TDS in the available company knowledge base. The figures marked as reference are based on the existing Haowei DD33-1C 2K chrome-effect silver system and public industry application references. They must not be used as final legal, quality-control or production specifications until confirmed by DD66-05 testing and an approved TDS.

Key Technical Advantages

Bright chrome-effect metallic appearance

The DD66-05 concept is designed to provide strong metallic character, bright silver appearance and a chrome-effect finish for automotive interior components. Metallic orientation, spray control, film build and the selected basecoat have a direct influence on the final visual result.

2K cured-film structure

The two-component system combines the silver coating with a dedicated hardener before application. This structure is intended to support a denser and more durable cured film than a simple air-drying 1K system, subject to formulation and performance validation.

Improved process durability potential

The reference 2K system is positioned for resistance to abrasion, scratching, solvent exposure, water and perspiration, weathering and elevated temperature. These claims must be verified on the final DD66-05 formulation and the complete substrate–primer–coating–clearcoat system.

Broad automotive plastic application

The proposed application range covers ABS, PC/ABS, PP, PE, PA6 and POM after suitable surface preparation. F-10 is used as the reference primer route for PP/PE, while POM-1 is the reference primer route for PA6/POM. Each substrate requires a compatibility and adhesion trial before mass production.

Alternative route to conventional electroplating

DD66-05 is positioned as a coating-based route for customers who need a metallic appearance without relying solely on conventional electroplating. The actual choice should consider appearance grade, abrasion requirements, chemical exposure, environmental compliance and production capacity.

B2B development support

Because the product is still in the parameter-confirmation stage, the strongest commercial offer is a controlled sampling and validation program: substrate identification, primer selection, ratio screening, spray-panel comparison, adhesion testing and final durability review before volume supply.

Professional Application Workflow

Recommended process logic

1. Substrate preparation — Remove contamination, previous coating residue, wax and oil. Prepare the plastic by an appropriate combination of cleaning, sanding, flame treatment or plasma treatment.
2. Primer selection — Use F-10 as the reference primer route for PP/PE. Use POM-1 as the reference primer route for PA6/POM. Confirm the primer and substrate combination through a test panel.
3. Basecoat preparation — Where a deeper chrome-like appearance is required, evaluate a suitable smooth, high-gloss basecoat as part of the complete system. The basecoat choice is a project variable and is not yet a confirmed DD66-05 specification.
4. Material conditioning — Stir the silver paint thoroughly before use so the metallic pigment is evenly dispersed. Do not introduce the hardener until the mixing step.
5. 2K mixing — Use the provisional starting ratio DD66-05 silver paint : hardener : DD-200 thinner = 10 : 1 : 25 ± 5. Mix only the quantity required for the validated working period. The final ratio and pot-life requirement must be established by DD66-05 testing.
6. Fine spray application — Apply controlled thin or medium coats using the selected spray equipment. Public industry references commonly use a fine spray setup around 0.8–1.0 mm and approximately 1.8–2.0 bar as a starting point, but these are not approved DD66-05 settings.
7. Flash-off and curing — Allow the coating system to flash off and cure according to the validated film build, booth temperature, humidity and clearcoat system. Do not publish a fixed DD66-05 drying time until confirmed.
8. Final validation — Check metallic appearance, adhesion, scratch and abrasion resistance, solvent resistance, water/perspiration resistance and complete-system durability before mass production.

Process control note

Chrome-effect coatings are sensitive to over-application, uneven film build, contamination and handling marks. Always prepare a test panel before production. The complete substrate–primer–basecoat–silver–clearcoat system must be approved together; a single silver-layer test cannot represent final product performance.

Website publishing note: The current page is a technical reference draft, not a final certified TDS. Replace provisional values, hardener code, packaging, shelf life, drying conditions and test claims with approved DD66-05 documents before publication.

Handling and storage

DD66-05 is planned as a solvent-based 2K coating system. Keep all components tightly closed, protect them from direct sunlight, heat sources and open flames, and provide adequate ventilation during application. Avoid skin and eye contact and use the personal protective equipment required by the final MSDS. The hardener may introduce additional occupational and transport requirements; the final formulation classification and regional chemical regulations must be confirmed before shipment.

For export to the EU, North America, Japan or other markets, confirm the applicable chemical, transport, labeling, VOC, worker-safety and environmental requirements for the final formulation and destination before shipment.

Product

DD66-05 is a proposed two-component chrome-effect silver coating for automotive interior plastic parts that require a bright, premium metallic appearance. The system is intended to combine a chrome-effect silver resin and metallic pigment package with a dedicated hardener, creating a coating route for customers seeking stronger cured-film performance than a basic 1K air-drying system may provide. The application concept follows the established Haowei 2K chrome-effect workflow: prepare the plastic surface, select the appropriate primer, evaluate the basecoat, mix the silver paint with hardener and thinner, apply controlled thin or medium coats, allow validated flash-off and curing, and approve the complete system before production. ABS, PC/ABS, PP, PE, PA6 and POM are the proposed substrate range, with F-10 used as the reference primer route for PP/PE and POM-1 for PA6/POM. The provisional starting ratio is silver paint : hardener : DD-200 thinner = 10:1:25 ± 5, referenced from the existing Haowei DD33-1C 2K system. Because DD66-05 does not yet have an approved model-specific TDS, all technical values, packaging, hardener identity and performance claims require laboratory confirmation, pilot spraying and batch-level documentation before commercial publication. Haowei Chemical can position the product around controlled sample development, OEM support and complete coating-system validation.
