Dowsil 1-2577 Low VOC is a one-part RTV silicone conformal coating supplied as a solvent-based elastoplastic resin solution with reduced volatile organic content. It is applied as a liquid and spreads evenly over electronic assemblies, providing smooth coverage and controlled leveling during processing. During curing, it reacts with atmospheric moisture and dries into a firm, uniform film, giving users a predictable coating experience with stable handling, clean appearance, and consistent surface quality suitable for regulated electronic manufacturing environments.

• Elastoplastic Film - After curing, Dowsil 1-2577 forms a resilient elastoplastic coating with strong surface durability. Typical cured film hardness supports abrasion resistance suitable for handling and assembly, while maintaining flexibility to avoid cracking. Coating thickness in the range of 25 to 75 microns can be achieved uniformly, supporting stable mechanical protection of coated surfaces.

  
  

• Low VOC System - The formulation is designed with reduced volatile organic compounds compared to conventional solvent-based silicone coatings. Specific gravity of the uncured material is approximately 0.88, indicating a lighter solvent system that supports lower solvent load. This helps reduce odor during application and supports compliance with low-emission manufacturing requirements.

  
  

• Room Cure - Dowsil 1-2577 cures at room temperature through moisture absorption, eliminating the need for thermal ovens in standard processing. Tack-free time is typically achieved within minutes to hours depending on film thickness and ambient humidity. This curing behavior supports simplified processing and flexible production scheduling.

  
  

• Heat Accelerated - After initial solvent flash-off, curing speed can be accelerated with mild heat exposure. Typical low-temperature bake conditions allow faster throughput without affecting final coating integrity. This option supports inline manufacturing processes where reduced cycle time is required.

  
  

• UV Indicator - The coating incorporates a UV inspection tracer to support quality control. Under ultraviolet light, the cured film provides clear visual contrast, allowing operators to verify coating coverage and thickness. This feature supports automated or manual inspection processes and reduces the risk of uncoated areas.

• PCB Protection - Dowsil 1-2577 is used to coat printed circuit boards to protect conductive traces and solder joints. Typical coating thicknesses of 25 to 50 microns provide electrical insulation while maintaining component visibility. This supports stable electrical performance and reduces risk of short circuits caused by surface contamination.

  
  

• Electronic Assemblies - In electronic assemblies, the coating is applied to protect components from environmental exposure. After curing, volume resistivity typically exceeds 1 × 10¹³ ohm·cm, supporting reliable insulation. This helps maintain signal integrity and operational stability in assembled electronics.

  
  

• Regulated Electronics - Dowsil 1-2577 is suitable for electronic products manufactured under regulated standards. The cured coating supports compliance with recognized industry requirements for electronic protective coatings. This makes it appropriate for applications where controlled materials and inspection-ready coatings are required.
