Kanto Kasei LK-123 Dry Film Lubricant is a specialty HANARL lubricant developed for precision sliding parts, mechanical mechanisms and electronic equipment where clean, controlled and efficient lubrication is required. It is particularly suitable for applications where conventional grease or oil may spread, bleed or contaminate nearby parts, making it a practical lubrication solution for precision devices, office automation equipment, electronic mechanisms and appearance-sensitive components.
Product Overview
Kanto Kasei is a Japanese manufacturer specializing in functional lubricants for precision electronics, mechanical assemblies, automotive electrical components and industrial equipment.
HANARL is Kanto Kasei’s specialty dry and semi-dry lubricant coating brand. The product family is designed to provide lubrication through a thin and uniform coating rather than a thick layer of conventional grease.
Kanto Kasei LK-123 Dry Film Lubricant belongs to this precision lubrication category and is commonly used where smooth sliding performance, reduced friction and cleaner mechanical operation are required.
HANARL dry lubricant technology uses a fluorine-based carrier system that allows lubricating ingredients to be distributed uniformly across the treated surface. After application, the fast-drying carrier evaporates and leaves a controlled lubricating film.
This thin-film approach can provide important advantages in compact electronic mechanisms where conventional grease may occupy too much space, spread into unwanted areas or affect the appearance of surrounding components.
Key Features and Advantages
Thin and Uniform Lubricating Film
One of the main advantages of HANARL dry-film technology is the ability to create a thin, consistent lubricant layer.
The coating can be applied to specific sliding areas without covering the entire component with grease. This makes the lubrication process easier to control in small and complicated precision assemblies.
Improved Sliding Performance
The lubricating film helps reduce friction between compatible contacting surfaces.
Improved sliding characteristics can support smoother movement, reduce operating resistance and improve the overall feel of precision mechanical mechanisms.
Reduced Wear
Repeated sliding contact can gradually wear resin, metal and other component surfaces.
Kanto Kasei LK-123 Dry Film Lubricant can help reduce direct contact between moving surfaces, supporting lower friction and reduced mechanical wear in appropriate applications.
Clean Lubrication
Traditional grease may migrate away from the original application area, particularly under pressure or repeated movement.
Dry-film lubrication provides a cleaner alternative for mechanisms where lubricant spreading could contaminate exterior surfaces, optical components or other nearby parts.
Reduced Oil Bleeding
Kanto Kasei specifically develops HANARL grades for applications where oil bleeding and lubricant migration are undesirable.
A controlled lubricating coating can therefore be especially useful near appearance-sensitive components and compact electronic assemblies.
Fast-Drying Application
HANARL products use a quick-drying carrier system designed to improve production efficiency.
After the coating is applied, the carrier evaporates quickly and leaves the functional lubricating film on the component surface.
This reduces the need for lengthy drying processes and can help improve cycle time in production environments.
Flexible Application Methods
Kanto Kasei’s HANARL family can be applied using several manufacturing methods.
Depending on the component and production process, application may include:
These methods make it possible to coat both small precision areas and larger component surfaces.
Consistent Application Quality
Because the lubricating ingredients are distributed within the carrier, uniform films can be formed without requiring highly specialized operator skills.
This can help improve consistency from component to component during mass production.
Suitable for Precision Mechanisms
Kanto Kasei LK-123 Dry Film Lubricant is especially relevant for compact assemblies where clearance is limited.
Thin lubrication helps avoid excessive grease accumulation while maintaining the required sliding performance.
Applications of Kanto Kasei LK-123 Dry Film Lubricant
Electronic Device Sliding Parts
HANARL dry lubricants are designed for sliding areas in electronic mechanisms where smooth movement and clean appearance are important.
Typical applications may include small rails, guides, covers and other movable components.
Light-Load Plastic Gears
LK-123 can be considered for compatible resin and plastic gear mechanisms where a thin lubricant coating is preferred over conventional grease.
Material compatibility should always be confirmed before mass production.
Printer and Copier Mechanisms
Office automation equipment contains numerous sliding and rotating mechanical components.
Dry-film lubricants can support smooth movement in printers, copiers and related equipment while reducing visible grease contamination.
Precision Sliding Rails
Kanto Kasei LK-123 Dry Film Lubricant may be used on compatible small rails, guides and precision sliding mechanisms that require low friction and controlled lubricant placement.
Camera and Optical Equipment
Lubrication around optical assemblies requires careful control because migrating grease can contaminate lenses or visible surfaces.
Kanto Kasei’s HANARL technology is specifically positioned for applications where oil spreading must be minimized.
Mobile and Electronic Device Mechanisms
Kanto Kasei has documented the use of HANARL lubricant coatings for sliding exterior portions of mobile phones and cameras.
These applications benefit from a thin lubricating layer that can provide durable sliding performance without unnecessary lubricant transfer.
Small Hinges and Moving Assemblies
Selected hinges, rotating joints and compact mechanical assemblies may also benefit from dry-film lubrication where conventional grease would be inconvenient.
Home Appliance Components
As electrical appliances have become smaller and more mechanically complex, lubrication is increasingly required around compact mechanisms and exterior sliding areas.
HANARL coatings provide an alternative to conventional lubrication methods for these applications.
Appearance-Sensitive Parts
Fully dry HANARL coatings are designed to reduce oil bleeding and transfer.
This type of lubrication is particularly useful near exterior or visible components where grease contamination would negatively affect product appearance.
Precision Machinery
Kanto Kasei LK-123 Dry Film Lubricant can also be considered for selected precision mechanical equipment requiring controlled low-friction movement and a clean lubricating film.
Material Compatibility

Country of Origin:
Japan
Important Technical Note
Kanto Kasei’s official website describes the technology, advantages and application methods of the HANARL dry lubricant coating family.
The manufacturer does not publicly display every individual HANARL model on its website because the product lineup is extensive and grades may be selected according to specific customer requirements.
For this reason, exact LK-123 specifications such as lubricant composition, solvent system, drying time, coating thickness, friction coefficient, operating temperature and service-life performance should be confirmed from the latest official Kanto Kasei LK-123 TDS or SDS before being used as guaranteed engineering values.
Selection and Application Considerations
Before mass production, users should evaluate LK-123 on the actual component materials.
Important factors include:
Substrate material
Surface condition
Operating temperature
Mechanical load
Sliding speed
Required service life
Lubricant application amount
Environmental exposure
The correct coating quantity is also important.
Excessive application is generally unnecessary because dry-film lubricants are designed to function through a thin controlled coating.
