[Case Study] A2 Fire-Rated Marble ACP: 9.0N/mm Peel Strength for Coastal Projects

1. The Challenge in Southeast Asia In coastal regions like Vietnam and Indonesia, high humidity (RH >80%) and salt spray often cause traditional ACP to peel or fade. B2B buyers need a solution that survives the monsoon season without structural failure.

We engineered a specialized Marble Aluminum Composite Panel that prioritizes core stability and coating integrity:

• Non-combustible Core: >90% inorganic mineral content (A2 Grade).

• Protective Coating: 25um - 28um PVDF (Kynar 500) for 20-year UV resistance.

• Visual Consistency: Batch-controlled marble patterns with Delta E <= 1.0.

• 180 Degree Peel Strength: >= 9.0 N/mm (Exceeding the 7.0 N/mm industry standard).

• Salt Spray Resistance: Passed 500-hour ASTM B117 test with zero corrosion.

• Surface Hardness: >= 2H Scratch Resistance.

• Safety: Complies with high-rise building fire codes.

• Durability: Designed for harsh tropical and coastal climates.

• Efficiency: 60% lighter than natural stone, reducing installation time and structural load.
