CJ-H1 Black Adhesive for Automotive Interior Wrapping | PVC Leather and Plastic Bonding | Haowei Chemical

CJ-H1 is a 2K solvent-based automotive interior adhesive for PVC leather, PP foam, PC and ABS, with strong heat-activated bonding and flexible wrapping performance.

CJ-H1 is a universal two-component solvent-based contact adhesive developed for automotive interior renovation, re-covering and custom wrapping. Commonly called Haowei Black Adhesive, it is designed for bonding PVC leather, foam-backed materials and interior plastic parts used in door panels, dashboards, headliners and seat-covering applications.

The adhesive provides strong initial and heat-activated tack, high-temperature resistance after curing, good plasticity and spray-friendly application. It is suitable for vacuum thermoforming and manual wrapping where controlled surface preparation, heat activation and pressing are required.

Technical Data Sheet (TDS)

Typical-data notice: Values shown above are typical data or application references. Actual batch-specific values should be confirmed against the relevant inspection report or CoA. The hardener code must be checked against the final commercial packaging because the application-guide archive contains a CJ-GHH code variant.

Key Technical Advantages

Strong initial and heat-activated bonding

CJ-H1 is designed to provide strong initial tack and effective heat-activated bonding. This supports controlled wrapping and forming operations on automotive interior trim materials.

High-temperature resistance after curing

The cured adhesive is intended for interior components exposed to elevated cabin temperatures, including dashboards and headliners. Final heat resistance should be confirmed on the actual material combination and bonding process.

Spray-friendly application

The adhesive is formulated for even spray application and is described in the TDS as non-clogging through standard spray guns. This supports consistent coverage on large panels and shaped trim components.

Flexible wrapping performance

After curing, the adhesive is designed to maintain plasticity and support manual wrapping or vacuum thermoforming. The application guide specifically notes that wrapped leather should retain its shape without deformation when the process is properly controlled.

Suitable for multiple interior materials

The reference application range includes PVC leather, coated PP foam, PC/ABS and ABS plastic parts. Difficult or adhesive-rejecting materials should be tested before production, and primer selection should follow the validated substrate process.

Suitable for automotive interior renovation

CJ-H1 can be positioned for professional interior renovation workshops, trim-part manufacturers, automotive component suppliers and distributors serving door-panel, dashboard, headliner and seat-covering projects.

Professional Application Workflow

1. Clean the materials — Remove grease, dust and other contaminants from the surfaces to be bonded.
2. Prepare plastic substrates — Sand the plastic where required. For PP, use the validated primer or PP adhesion promoter process. PC and ABS do not require primer in the referenced guide, but difficult materials must be tested.
3. Mix the 2K adhesive — Mix CJ-H1 adhesive and CJ-CHH hardener at 20 : 1. Mix only the quantity required for the intended working period.
4. Spray evenly — Apply the mixed adhesive uniformly to the surfaces to be bonded using the selected spray gun or nozzle.
5. Flash off — Allow the sprayed film to dry naturally until it loses surface tack. At 30–40 °C ambient, the reference open time is approximately 60–120 minutes.
6. Heat activate and laminate — During bonding, activate the adhesive with hot air at 45–65 °C. The application guide references at least 15 seconds of industrial heat-gun activation for full activation.
7. Press and position — Heat, position and press in one controlled operation. Appropriate pressure improves the bonding result.
8. Cure and validate — Allow the assembly to cool and cure. Bond strength is referenced as reaching a maximum after approximately 24 hours; full heat-resistance development is referenced at 72 hours. Validate the actual material combination before mass production.

Handling and storage

CJ-H1 is a solvent-based flammable adhesive. Keep containers tightly closed, store at a constant 5–38 °C, avoid direct sunlight, and keep away from heat sources, open flames and ignition sources. Use adequate ventilation during spraying and heat activation. Avoid skin and eye contact and follow the final MSDS for personal protection, storage, first-aid and transport requirements.

Reseal the adhesive container immediately after each use to limit solvent evaporation and thickening. Reseal the hardener immediately after each use because moisture exposure may cause premature curing or product failure. Use mixed adhesive ideally within 5 hours; longer sealed storage is not recommended by the application guide.

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

Product

CJ-H1 is a universal 2K solvent-based black adhesive developed for automotive interior renovation, re-covering and custom wrapping. It is suitable for bonding PVC leather, coated PP foam materials, PC/ABS and ABS plastic parts used in door panels, dashboards, headliners and seat-covering applications. The adhesive is designed to provide strong initial tack, heat-activated bonding, high-temperature resistance after curing and flexible wrapping performance. It can be applied by spray gun or nozzle after mixing with CJ-CHH hardener at the reference ratio of 20:1. The recommended workflow is to clean the materials, prepare the plastic substrate, spray the mixed adhesive evenly, allow the film to lose surface tack, activate it with hot air at 45–65 °C, and press the materials together in a controlled operation. At 30–40 °C ambient, the application guide references an open time of approximately 60–120 minutes; industrial heat-gun activation is referenced at at least 15 seconds. Bond strength is referenced as reaching a maximum after approximately 24 hours, while the guide references 72 hours for maximum heat resistance. Haowei Chemical supplies the product in 18 L pails with a net weight of 15 kg, as well as a 1 L small pack with a net weight of 0.8 kg. Before publication or export, confirm the hardener code because the formal TDS lists CJ-CHH while an archived application note uses CJ-GHH.
