What is BCHP?
copper hydroxy-phosphate (BCHP)
BCHP (Copper hydroxy-phosphate) for Laser Marking Pigments and LDS/MID.
Technical owner: Aurexene Materials Engineering Team · Last updated: 2026-07-25
What It Is Not
- BCHP is basic copper hydroxy phosphate, not black carbon, carbon black, or an LDS/MID catalyst by default.
When Not to Use It
- Do not use BCHP when the required laser response mechanism, polymer compatibility, color, or process window has not been validated in the target resin.
Intrinsic Screening Summary
- Identity screen
- Cu2(OH)PO4; Green crystalline powder; orthorhombic copper hydroxyphosphate
- Intrinsic feature
- BCHP requires source-backed function review before public grade-level positioning. composition, form, processing route, and the linked application requirements.
Application Fit
Selection & Validation Framework
| Decision Question | Material-Level Answer |
|---|---|
| Integration and processing criteria | Required for: Laser Marking Pigments, LDS/MID, and LASER Curable Systems. Measure: particle distribution; settling; redispersion; storage stability; moisture exposure. Sample state: final host formulation or part state. Failure signals: Use when evaluating Laser Marking Pigments / LDS/MID / LASER Curable Systems formulations or systems.. |
