P-Bar Type T Fluorocarbon Barrier Film High-Temp Stable Oleophobic Film for Electronics
Detailed Information
- Product Number: P-Bar Type T
- P-Bar Type T is manufactured for the fluorocarbon barrier film. While"Type P"describes a general application style or alternative formulation category, Type T is used for primary barrier film solutions.
- Primary Function: Acts as an oleophobic barrier film to stop oils, greases, and fluids from creeping, migrating, or bleeding away from lubricated components and contaminating sensitive electronics, optics, or switches.
- Concentrations Available: Offered in various active-ingredient weight percentages depending on the desired barrier thickness:
· Type T 0.2% (Thinnest film, ideal for delicate electrical contacts)
· Type T 1.0% (Standard general-purpose barrier)
· Type T 2.0% (Thicker barrier film for aggressive containment needs)
- Surface Energy: Creates an ultra-low surface energy barrier (approximately 10 dynes/cm), forcing migrating oils to bead up like water on a waxed surface.
- Temperature Resistance: Stable in operational environments up to +200℃.
- Carrier Solvent: Dispersed in a fast-evaporating fluorinated solvent carrier that air-dries within minutes.

Application Fields
- Bearings and Actuators: Applied as a perimeter"doughnut"ring around pivot shafts, housing seats, or bearing shoulders. It prevents lubricating grease from bleeding onto nearby components.
- Optics and Cameras: Used to keep oils away from lenses, prisms, and optical glass (historically used to protect the mast cameras on Mars Rovers) to prevent distortion or ruined refraction indexes.
- Electrical Contacts and Switches: Painted around the perimeters of printed circuit boards, connectors, and potentiometers to prevent creeping oils from fouling electrical pathways.
- Fluidics & Dispensers: Used on spray heads and nozzles to keep liquids from creeping up and degrading nozzle performance.

How It Is Applied
1. Surface Preparation: The surface (metal, plastic, or glass) must be thoroughly cleaned and degreased so the barrier film adheres correctly.
2. Application Methods: The liquid solution can be applied via:
- Dipping the component directly into the solution.
- Spraying it uniformly onto the target zone.
- Brushing it onto small or localized areas.
1. Drying/Curing: * Standard Air Dry: Takes about 5 minutes at room temperature as the fluorinated carrier solvent evaporates, leaving behind an invisible micro-film.
- Standard Bake: Baking for 10 minutes at 90℃ can increase abrasion resistance.
- Vacuum/Low-Outgassing Bake: Baking for roughly 2 hours at 120℃ is often used for aerospace or vacuum environments.

Critical Rule of Usage
- Never apply P-Bar Type T directly to friction surfaces (such as bearing balls, raceways, or active electrical contact points) that actually require lubrication. Doing so will repel the required lubricant, causing the component to run dry and fail prematurely.
