Product Description
HW-3306 2K Soft-Feel Coating for Automotive Interior Plastics | Haowei Chemical
HW-3306 is a 2K polyurethane soft-feel coating for automotive interior plastics, delivering a smooth tactile finish, abrasion resistance and chemical-wipe durability.
HW-3306 is a two-component solvent-based polyurethane soft-feel coating developed for automotive interior plastic parts. The coating is designed to form a smooth, delicate tactile surface with a baby-skin or peach-skin feel, upgrading both the appearance and touch quality of hard plastic components.
The coating cures through crosslinking with an aliphatic isocyanate hardener to form a dense and tough film. It is intended for interior applications where soft-touch quality, abrasion resistance, scratch resistance, flexibility and resistance to daily contaminants are important.
Technical Data Sheet (TDS)
Typical-data notice: The values above are extracted from the FG-3306 reference TDS. Actual batch-specific values should be confirmed against the relevant inspection report or CoA. HW-3306 must not be treated as a formally approved specification until the commercial code and technical documents are aligned.
Key Technical Advantages
Smooth soft-feel touch
HW-3306 is designed to create a delicate baby-skin or peach-skin tactile finish. It helps improve the touch quality of hard plastic interior components and supports a more premium interior appearance.
2K polyurethane coating structure
The coating crosslinks with an aliphatic isocyanate hardener to form a dense and tough polyurethane film. Proper ratio control, mixing, spraying and curing are essential to achieving the intended tactile and physical performance.
Abrasion, scratch and flexibility performance
The FG-3306 reference TDS identifies excellent abrasion resistance, scratch resistance and good flexibility. These properties are relevant to interior parts exposed to repeated touching, rubbing and handling.
Resistance to daily interior contaminants
The reference TDS lists resistance to wet and dry wiping, perspiration, sunscreen, cleaning agents and aging. Final performance should be verified on the actual substrate, primer, color coat and complete HW-3306 coating system.
Multi-substrate application
The system is intended for ABS, PC/ABS, PP, PE, PA6 and POM after suitable surface preparation. F-10 primer is required for PP/PE, while POM-1 primer is required for PA6/POM.
B2B appearance-and-touch solution
HW-3306 can be positioned for automotive interior refinishing workshops, trim-part manufacturers, automotive component suppliers and distributors seeking a coating that combines tactile quality with physical and chemical resistance.
Professional Application Workflow
- Clean the substrate — Remove dirt, grease and surface contamination with the approved cleaning process.
- Strip and prepare — Remove old coating or surface film where required, allow the surface to dry, and sand according to the validated repair system.
- Select the primer — Use F-10 primer for PP/PE. Use POM-1 primer for PA6/POM. Confirm adhesion on the actual substrate before production.
- Prepare the coating — Stir HW-3306 soft-feel clear coat thoroughly before mixing.
- Mix the 2K system — Use clear coat : 3390 hardener : FG-C2 thinner = 10 : 1 : 5 ± 2 as the reference starting ratio. The final ratio and applicable working period should be confirmed during process validation.
- Filter and spray — Filter the mixed coating when required and apply with the selected spray equipment using a uniform, controlled process.
- Cure under validated conditions — Establish drying and curing conditions for the actual substrate, coating thickness and equipment. The available FG-3306 TDS does not specify a universal fixed drying time.
- Validate the finish — Check soft-feel uniformity, appearance, adhesion, abrasion resistance, scratch resistance, wiping resistance and chemical resistance before mass production.

B2B Commercial and Compliance Support
Supply format
- HW-3306 soft-feel coating: reference 18 kg/pail.
- FG-C2 thinner: 18 kg/pail.
- 3390 hardener: 1 kg/bottle.

Publishing note: The available technical file uses FG-3306 as the product code. Replace the reference code with HW-3306 only after the commercial label, TDS and MSDS have been aligned.
Handling and storage
HW-3306 is a solvent-based 2K polyurethane coating. Keep all components tightly closed, store at a constant 5–38 °C, avoid direct sunlight, and keep away from heat sources and open flames. Provide adequate ventilation during application and avoid skin and eye contact. The hardener may introduce additional occupational-safety and transport requirements. Refer to the final MSDS for personal protection, storage, first-aid and transport information.
For export to the EU, North America, Japan or other markets, confirm the applicable chemical, labeling, transport, VOC, worker-safety and environmental requirements for the final formulation and destination before shipment.
