Technical Information
HumiSeal 1B31 is a clear, fast-drying acrylic conformal coating in aerosol form, widely used for protecting printed circuit boards and electronic assemblies from moisture, dust, chemicals, and fungal contamination in harsh operating environments. The acrylic formulation provides an excellent balance of moisture resistance, electrical insulation, and ease of removal for rework — a key advantage of acrylic conformal coatings over urethane or silicone alternatives. The 11.5 oz aerosol can delivers a uniform, controlled spray coat on PCBs and assemblies without the need for spray equipment. HumiSeal 1B31 is one of the most widely specified conformal coatings in electronics manufacturing globally.
Why Choose HumiSeal 1B31?
- Industry-Standard Acrylic Formula — HumiSeal 1B31 is one of the most widely used conformal coatings globally
- Aerosol Convenience — Uniform spray coat without spray equipment for MRO and prototype use
- Easy Rework Removal — Acrylic formula dissolves in standard solvents for component rework
- Fast-Drying — Rapid tack-free time for efficient production and repair workflows
- Clear Coating — Transparent film allows visual inspection of coated PCB assemblies
Frequently Asked Questions
Q: What is HumiSeal 1B31 Clear Acrylic Conformal Coating used for?
A: HumiSeal 1B31 is used for conformal coating of printed circuit boards and electronic assemblies to protect against moisture, dust, chemicals, and fungal contamination in military, industrial, automotive, and consumer electronics applications.
Q: What is the MPN for HumiSeal 1B31 11.5 oz Aerosol?
A: The Manufacturer Part Number (MPN) is 19863.
Q: What IPC specification does HumiSeal 1B31 meet?
A: HumiSeal 1B31 meets IPC-CC-830 qualification requirements for conformal coatings. Consult the current HumiSeal 1B31 datasheet for specific IPC class qualifications and MIL-I-46058 listing status.
Q: How is HumiSeal 1B31 removed for PCB rework?
A: HumiSeal 1B31 acrylic conformal coating can be removed for rework using standard acrylic conformal coating removers or isopropyl alcohol. Localized removal with a solvent-soaked swab or aerosol stripper allows component replacement without full board stripping.
Q: How many PCBs can a 11.5 oz aerosol of HumiSeal 1B31 coat?
A: Coverage depends on PCB size and coating thickness applied. Consult the HumiSeal 1B31 datasheet for coverage rate data. For production-scale coating, liquid HumiSeal 1B31 in bulk is more economical than aerosol cans.
