Product Description
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 ensuring excellent adhesion, flexibility, and chemical resistance. The series offers multiple viscosity options to accommodate different application methods and features a secondary ambient curing mechanism, making it ideal for electronics protection in high-performance environments.
Features of HumiSeal® UVA300 Series
- Curing tack-free under LED UV light at 385nm or 395nm.
- Offering multiple viscosity levels for different coating equipment.
- Allowing application at elevated temperatures for increased process stability.
- Providing secondary ambient curing for unexposed areas within 7 days.
- Fluorescing under UV light to enable easy inspection.
- Ensuring high flexibility for superior adhesion and thermal cycling performance.
- Delivering excellent chemical and moisture resistance for enhanced durability.
- Being non-flammable, VOC-free, solvent-free, and RoHS compliant.
Applications of HumiSeal® UVA300 Series
- Electronics Protection: Coating PCBs and sensitive components to prevent environmental damage.
- Selective Coating Processes: Suitable for airless film coating, swirl, spray, and needle dispensing.
- Automotive & Aerospace Electronics: Enhancing durability and resistance in extreme conditions.
- High-Reliability Industrial Applications: Providing long-term moisture and chemical protection.
- Manual Rework & Touch-Ups: Applied via brushing for localized repairs.
