Product Introduction
The HumiSeal® UVA300 Series is a one-part, high-solids, dual-cure acrylated polyurethane conformal coating designed for LED UV curing. This advanced technology reduces energy consumption, lowers curing temperatures, and extends equipment lifespan while offering excellent adhesion, flexibility, and chemical resistance. Multiple viscosity options cater to different application methods.
HumiSeal® UVA300 Series Features:
- Cures tack-free under LED UV light at 385nm or 395nm.
- Multiple viscosity options for various coating equipment.
- Provides secondary ambient curing for unexposed areas.
- Fluoresces under UV light for easy inspection.
- Non-flammable, VOC-free, and solvent-free.
HumiSeal® UVA300 Series Applications:
- Electronics Protection: Coats PCBs and sensitive components to prevent environmental damage.
- Selective Coating Processes: Suitable for airless film coating, swirl, spray, and needle dispensing.
- Automotive & Aerospace Electronics: Enhances durability and resistance in extreme conditions.
- High-Reliability Industrial Applications: Offers long-term protection from moisture and chemicals.
- Manual Rework & Touch-Ups: Applied via brushing for localized repairs.
