HumiSeal 1B31 is an industry-standard, single-component acrylic coating. It gives printed circuit assemblies excellent protection from moisture and the environment.
Key Features of HumiSeal 1B31
- 200 cPs viscosity
- 10 to 30 minute touch dry
- Perfect for high-volume lines
Flexible and Easy to Repair
This fast-drying formula is known for its excellent flexibility. In addition, you can remove it with chemical stripping, so rework is simple.
Quick Inspection
The coating fluoresces under UV light. As a result, inspectors can quickly confirm that no critical component is left unprotected.
Efficient in Production
With a viscosity of 200 cPs and a touch-dry time of 10 to 30 minutes, 1B31 keeps lines moving. So it is highly efficient for high-volume production.
Where It Works Best
1B31 suits a wide range of printed circuit assemblies. For example, it protects consumer devices, industrial control boards and other electronics that face humidity and airborne contaminants.
Because it is a single-component formula, there is nothing to mix before use. As a result, operators can get started quickly.
Simple Rework When You Need It
Repairs are part of real-world production. Fortunately, you can remove this acrylic coating with chemical stripping. So technicians can reach a faulty part, fix it and then recoat the area without scrapping the board.
In addition, the UV tracer makes it easy to confirm the repaired area is fully covered again.
Why Choose HumiSeal 1B31?
HumiSeal 1B31 offers a strong barrier against humidity and contaminants. Meanwhile, it maintains high insulation resistance.
For example, it is an ideal choice for consumer electronics and industrial controls. Therefore, it delivers reliable, long-term performance in varied conditions.
