Humiseal 1a68 Updated Page

Typically applied at a thickness of 25 to 75 microns (1-3 mils). Storage and Maintenance

1A68 is a (1K) system, meaning it does not require mixing prior to use. It cures via solvent evaporation. As the solvents evaporate, the acrylic resin forms a clear, flexible film over the circuit board. This eliminates the pot-life issues associated with two-component systems, reducing waste and simplifying inventory management.

For high-volume production, 1A68 can be used with conventional spray equipment. It is typically thinned in a 1:1 ratio with HumiSeal Thinner 521 to ensure a pinhole-free finish. humiseal 1a68

HumiSeal 1A68 is a high-performance, single-component polyurethane conformal coating designed to protect printed circuit boards (PCBs) from harsh environmental conditions. It is particularly valued for its balance of chemical resistance and ease of application. Caplinq +1 Key Characteristics Chemistry: It is a moisture-curing urethane coating. Protection: Offers superior resistance to chemicals and abrasion. Inspection: The coating contains a UV tracer, allowing it to fluoresce under blacklight for easy visual inspection of coating coverage. Compliance: It is IPC-CC-830 compliant, RoHS compliant, and UL recognized. Caplinq +2 Application & Curing Versatility: Can be applied via spraying, dipping, or brushing. Cure Profile: It cures at room temperature through reaction with atmospheric moisture, though the process can be accelerated with mild heat. Repairability: While it provides a tough, durable finish, it can be removed using specific strippers if board repair is necessary. Caplinq +2 Primary Use Cases It is typically selected for general PCB applications where standard acrylics might not provide enough chemical or mechanical protection, but where the extreme flexibility of a silicone isn't required. Detailed safety and handling protocols can be found in the HumiSeal 1A68 Safety Data Sheet provided by ConRo . Are you looking for specific

Modern formulations of 1A68 are designed to meet rigorous industry standards. It typically complies with IPC-CC-830 and military specifications (such as MIL-I-46058C), making it suitable for aerospace, automotive, and consumer electronics applications. Typically applied at a thickness of 25 to

A significant advantage of HumiSeal 1A68 is its reworkability. Because it cures through solvent evaporation rather than cross-linking polymerization, it remains soluble in specific solvents. If a component needs to be replaced, the coating can be softened and removed using HumiSeal’s proprietary Thinner 521 or common solvents like isopropyl alcohol (IPA) and xylene. This ease of removal contrasts with polyurethane coatings, which often require aggressive chemical strippers or thermal methods to remove.

Accelerated: Can be cured in 30 hours at 76°C or 20 hours at 88°C. As the solvents evaporate, the acrylic resin forms

HumiSeal 1A68 is an acrylic-based coating. Acrylics are generally favored for their ease of application, rapid drying times, and simple rework processes. Unlike epoxies or polyurethanes, which can be difficult to remove once cured, acrylics offer a balance between protection and repairability.
