## Key takeaways

- Kae Hwa's InduBarrier™ Type 5B and 6B laminates are engineered for biohazard, pharmaceutical, and automotive coating environments — different use cases than Type 4B.
- Type 5B (EN 13982-1) blocks dry biological aerosols and particulates, making it suited to biohazard and pharmaceutical work where APIs and powder chemicals must be contained.
- Type 6B (EN 13034) is a lightweight, low-linting, limited-splash fabric that blocks automotive paint sprays and solvents while still letting body heat dissipate.

## Frequently asked questions

### Can Type 5B and Type 6B materials be safely used for biohazard, pharmaceutical, and automotive coating applications?

Yes. Kae Hwa's InduBarrier Type 5B and 6B laminates are engineered for exactly these controlled environments: Type 5B (EN 13982-1) blocks dry biological aerosols and particulates for biohazard and pharmaceutical work where APIs and powder chemicals must be contained, while Type 6B (EN 13034) is a lightweight, low-linting, limited-splash fabric that blocks automotive paint sprays and solvents while still letting body heat dissipate. Unlike Type 4B, which is built for heavy liquid sprays, 5B and 6B trade some liquid resistance for lighter weight and better mobility in dry-particulate or light-splash settings.

### When should Type 4B be used instead of Type 5B or 6B?

Type 4B is built for heavy liquid sprays, so it's the right choice when workers face substantial liquid chemical exposure. Type 5B and 6B trade some of that liquid resistance for lighter weight and better mobility, making them better suited to dry-particulate, biological-aerosol, or light-splash environments like biohazard containment or automotive paint work.
