ABAK spray coating solvent resistance
문제 현상
Insufficient solvent resistance after ABAK spray coating; the coating attacks the substrate.
원인 분석
There is little research on ABAK spray coating solvent resistance; solvents attack the alloy; compatibility of coating and substrate; internal stress cracking; surface pretreatment.；during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Solvent-resistant coating selection; ②substrate pretreatment; ③stress management; ④compatibility testing; ⑤process verification.；after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
ABAK spray coating solvent resistance is an application detail; matching of coating and substrate; testing ensures long-term quality.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
