3M Novec 1720 Electronic Grade Coating: Product Analysis
Product Overview
3M Novec 1720 Electronic Grade Coating is a clear, low-viscosity, low-surface-tension solution of a fluorosilane polymer carried in 3M™ Novec™ 7100 Engineered Fluid. Specifically engineered for easy-clean and anti-smudge performance on various surfaces including glass flat panel displays and mobile electronic device components, this coating represents a significant advancement in modern electronic protection technology.
The coating dries to form a thin, transparent, permanent film exhibiting exceptional hydrophobic and oleophobic properties. Post-curing treatment further enhances durability and abrasion resistance. With non-flammable characteristics, low toxicity, zero ozone depletion potential, and RoHS compliance, the product provides reliable surface protection solutions for electronic devices.
In-Depth Product Characteristics
1.Fundamental Physical Properties
Novec 1720 demonstrates an optimized combination of physical parameters: low viscosity and low surface tension ensure uniform coverage over complex surface structures; rapid drying capability enables surface drying within seconds, significantly improving production efficiency; excellent optical transparency maintains original visual effects of display devices without adding haze or clarity loss.
2.Protective Performance Features
The coating exhibits outstanding static contact angle performance, maintaining high contact angles for both water and hexadecane, demonstrating superior anti-wetting capability. After 2,500 linear abrasion cycles, contact angles remain stable, showing exceptional wear resistance and durability. This long-lasting protective effect ensures product reliability throughout extended usage.
Process Technology and Application Methods
1.Diversified Application Processes
Novec 1720 supports multiple application methods including dipping, spraying, or selective deposition, accommodating different production requirements and equipment configurations. This process flexibility enables integration into existing production lines without major equipment modifications.
2.Process Control Essentials
Moisture contact must be strictly controlled during application as water significantly reduces pot life. Surfaces to be coated must be clean and dry to ensure coating adhesion and uniformity. The rapid solvent evaporation enables fluoropolymer film drying within minutes, but thermal curing in an oven is recommended for optimal performance.
Comprehensive Application Solutions
Display Device Protection
For touch screens, LCD displays, flat panel displays, and other display equipment, Novec 1720 provides effective easy-clean and anti-smudge protection. Its transparent characteristics ensure no impact on display quality while offering durable protection for frequently contacted surfaces, particularly suitable for mobile electronic handheld devices such as smartphones and tablets.
Functional Coating Applications
As an anti-stiction coating, the product is suitable for liquid crystal displays, micromotors, or Micro-Electro-Mechanical Systems (MEMS) components, effectively reducing adhesion between parts. Simultaneously, as an anti-migration coating, it can be used for displays, spindle motors, or lubricated electronic parts, preventing contamination caused by lubricant migration.
Anti-corrosion Protection Solutions
The product provides anti-corrosion protection for various materials and components. The dense film formed by the fluorosilane polymer effectively blocks moisture and corrosive substances, extending the service life of electronic equipment.
