3M Novec 1710 Electronic Grade Coating Product Analysis
Product Overview
3M Novec 1710 Electronic Grade Coating is a high-concentration, single-component fluorinated polymer solution using 3M Novec 7100DL Engineered Fluid as the solvent, characterized by low viscosity and low surface tension. Designed for moisture and corrosion protection of printed circuit boards and electronic components, it dries to form an ultra-thin, transparent coating with excellent hydrophobic and oleophobic properties. Beyond direct use as a protective coating, 1710 can also serve as a concentrate to replenish solid content in application baths or be blended with other materials to create customized coating systems. The product requires no curing, offers easy application, and features strong environmental and safety credentials including non-flammability, zero ozone depletion potential, low toxicity, low global warming potential, RoHS compliance, and U.S. EPA VOC exemption.
Physicochemical Properties Analysis
1.Stable High-Solids System
Novec 1710 has a density of 1.5 g/ml (@23°C), a boiling point of 61°C, and no flash point by closed-cup test, ensuring safe handling. With a viscosity of 4.3 cP, it is suitable for dip, brush, and selective dispensing processes, achieving handling capability within two minutes at room temperature to support efficient production.
2.Well-Balanced Dry Film Performance
The cured coating thickness can be adjusted from 0.1 to 10 microns and exhibits excellent thermal stability, maintaining protective performance after 24 hours at 175°C, with a glass transition temperature (Tg) of 44.5°C. Static contact angles of 105° (water) and 65° (hexadecane) demonstrate strong dual-phobic properties. Electrically, it offers a dielectric constant of 3.2 (@1kHz), dissipation factor of 0.002, and dielectric strength of 2000 V/mil, suitable for most electronic insulation applications.
Application Performance and Solutions
Adaptable to Diverse Protection Needs
Novec 1710 can serve as a high-performance alternative to traditional conformal coatings, providing reliable protection against moisture, chemical vapors, and ion migration for PCBs and electronic components. It can also be used as a high-concentration additive to enhance the overall protective performance of composite coating systems.
Supports Continuous Production and Maintenance
Its function as a concentrate is particularly valuable for long-running application baths, allowing easy replenishment of solid content to maintain consistent coating performance, reduce the frequency of bath replacement, and improve production continuity and cost efficiency.
Technical Advantages and Process Benefits
Versatile and Cost-Effective Design
1710 can be used as a ready-to-apply coating or as a raw material for dilution or formulation, delivering multiple functions from a single product. This reduces inventory variety and supply chain complexity for users.
Excellent Process Compatibility and Control
The coating supports various application methods including dip, brush, and selective dispensing, with viscosity and film thickness easily adjustable through dilution. It dries rapidly without post-treatment, making it compatible with mainstream electronics manufacturing processes.
Easy Rework and Maintenance
The coating can be dissolved and removed using Novec 72DA (recommended) or 7100DL Engineered Fluid, facilitating rework and repair. As a bath replenisher, it also simplifies maintenance procedures and extends overall system life.
