CONFORMAL COATING

Nectec’s Conformal Coating solutions combine diverse material technologies with environmental durability to protect electronic components. With types ranging from acrylic to silicone, they offer tailored protection for circuit boards in automotive, aerospace, and industrial sectors. Key features—including moisture/salt spray resistance, high thermal stability, and easy repairability—ensure long-term reliability. The eco-friendly formulations (e.g., halogen-free AC-UV401) meet safety standards, while fast-curing and dual-curing options enhance production efficiency. Backed by technical parameters like high insulation resistance and thermal shock tolerance, these coatings are essential for extending device lifespan in challenging environments .

Description

  1. Diverse Material Types for Versatile Applications
    Offers modified acrylic (AC-U201), polyurethane (AC-U301), UV+moisture dual-curing (AC-UV401), and silicone (AC-S501) types, each tailored for specific needs. For example, AC-S501’s silicone formula suits high-vibration environments, while AC-UV401’s dual curing is ideal for high-temperature automotive applications .
  2. Excellent Environmental Protection
    Provides robust insulation, moisture resistance, and salt spray protection (e.g., AC-U301), preventing corrosion and extending component lifespan. It also inhibits mold growth and shields against dust and chemical erosion .
  3. High Thermal and Electrical Performance
    Maintains stability across wide temperature ranges (e.g., AC-S501 resists thermal shock), with high electrical insulation (≥10⁹ Ω) and fast curing (e.g., AC-U201 dries at room temperature). These features ensure reliability in harsh conditions .
  4. Easy Application and Repairability
    Formulations like AC-U201 and AC-S501 allow simple repair due to their film properties, while UV+moisture curing (AC-UV401) enables efficient production processes. Adhesion to various materials ensures consistent coverage .
