• Store unmixed components between 18°C and 25°C for 24 hours before use
• Mix A530 primer base for 10 minutes using pneumatic or oscillating mixer
• Mix base and hardener until homogeneous
• Add Thinner E in two stages
• Application mixture temperature: 15°C to 35°C
• Recommended filtration: 120-150 µm filter

Application Equipment

Defect Correction Guidance

• If recoating time is exceeded, reactivate surface using Scotch-Brite
• For micro-bubbles, runs, rejects, or inclusions:
• Reactivate surface using abrasive paper grade 220 to 320
• Remove dust and clean with approved cleaning product
• Apply a thin coat of AEROPRIM 530 to achieve required thickness
• For significant defects, remove primer using approved chemical paint remover or plastic media
• Repeat surface treatment where required

Cleaning & Maintenance

• Clean application equipment using suitable cleaning thinner such as P
• Ensure spray equipment is free from contamination before reuse
