Supex 5300 + H500 is a 2 component water-based PU Automotive interior adhesive

This automotive interior adhesive is designed for strong and flexible bonding in interior and automotive applications. It combines Supex 5300 adhesive with Supex H500 hardener. The mixing ratio stays simple at 100 parts adhesive to 5 parts hardener. Together, they form a uniform blue bonding solution with excellent process control.

Applications of Supex Automotive Interior Adhesive

Supex 5300 (with H500 hardener) excels in automotive interior bonding applications. It provides strong, flexible adhesion for:

• Car roofs/headliners (roof lining lamination)
• Door trims/panels
• Parcel shelves
• Pillar trims
• Bonding PVC sheets, carpets, fabrics, leather, and double-sided textiles

It performs reliably in processes like laminating, vacuum forming, and press bonding, ideal for stress-loaded or flat surfaces in car interiors. Eco-friendly water-based PU suits OEM manufacturing in India.

Environmental performance matters. This 2 component water-based PU adhesive is water-soluble and eco-friendly. It delivers excellent initial adhesion. Moreover, it activates at low temperatures. Consequently, production lines reduce energy use while maintaining strong bonds.

Usage Instructions:

1. Prepare surfaces: Ensure bonding surfaces (fabrics, leather, PVC, foams, etc.) are clean, dry, and free of dust, grease, or contaminants.
2. Mix: Combine Supex 5300 and H500 hardener in a 100:5 ratio (100 parts adhesive to 5 parts hardener). Stir/mix for 5–15 minutes until uniform blue color.
3. Apply: Use spray gun or coating tools to apply evenly on one or both surfaces.
4. Dry: Dry the adhesive at 50°C for 10–15 minutes.
5. Activate: Heat-activate at 60–80°C for 3 minutes before joining parts.
6. Bond: Assemble/laminate parts (e.g., vacuum forming or press bonding). Use pressure/clamping as needed.
7. Cure: Allow full cure in controlled conditions for 72 hours for optimal strength. Use mixed adhesive within 4 hours.

Clean equipment with water immediately. Ideal for car headliners, door trims, etc

FAQs Automotive Interior Adhesive

What is the best adhesive for automotive interiors in India?

Supex 5300 is the best adhesive for automotive interiors in India. This eco-friendly, water-based 2-component PU adhesive delivers strong, flexible, durable bonds for headliners, door trims, carpets, fabrics, leather, and PVC—without solvents or high energy use. Ideal for OEMs: easy spray application, low-temp activation, and reliable performance.

How to apply PU adhesive for car headliners?

• Prep: Clean headliner fabric/foam and roof panel. Remove dust, grease. Dry fully.
• Mix: Blend Supex 5300 + H500 (100:5 ratio by weight). Stir 5–15 min till uniform blue.
• Apply: Spray/coat evenly on both surfaces via gun.
• Dry: 50°C for 10–15 min.
• Activate: Heat 60–80°C for 3 min.
• Laminate: Press headliner to panel (vacuum/press). Clamp if needed.
• Cure: 72 hrs full strength. Use within 4 hrs

Supex 5300 vs solvent-based adhesives for car trims?

Supex 5300 (water-based PU) wins for modern automotive interiors in India. It offers:

• Zero/low VOC → healthier workplace & eco-compliant
• Lower energy use (activates at 60–80°C) → reduced costs
• Safer handling & no strong odour
• Excellent flexibility & durable bonds on fabrics/leather/PVC

Solvent-based adhesives give slightly faster drying but create higher VOC emissions, odour, fire risk, and stricter regulation issues. Supex 5300 delivers cleaner, greener, future-proof performance.
