Dry Film Lubricants

Solid-phase lubrication coatings that provide intermittent dry lubrication and friction reduction where liquid lubricants are impractical — extreme temperatures, vacuum, clean-room, or contamination-critical environments.

Technology Overview

Intermittent Dry Lubrication to Withstand Extreme Conditions

Dry film lubricant coatings are engineered to reduce friction and prevent wear in applications where liquid lubricants are impractical — operating under extreme temperatures, vacuum environments, radiation exposure, or where contamination from oil or grease is unacceptable.

Calico's CT series dry film lubricant line uses advanced formulations of molybdenum disulfide (MoS₂), PTFE, graphite, and tungsten disulfide applied via spray process with substrate-appropriate surface preparation. These coatings create a solid, low-friction surface that provides intermittent dry lubrication throughout the component's operational life.

Typical thickness ranges from 0.00025" to 0.002", making dry film lubricants suitable for assemblies with tight tolerances where liquid lubricants would create contamination risk or dimensional interference. Applications span aerospace fasteners, defense mechanisms, firearms components, medical devices, and industrial machinery requiring maintenance-free, clean-operating surfaces.

Process Overview

Precision at Every Step

Step 01

Surface Preparation

Substrate-specific cleaning and surface profiling. Mechanical abrasion or chemical etching creates optimal surface energy and anchor points for the coating to bond effectively.

Step 02

Masking

Precision masking protects critical mating surfaces, threads, and features where coating would affect assembly clearances or functional performance.

Step 03

Spray Application

The dry film formulation is spray-applied in controlled thickness passes. Film build is monitored to achieve 0.00025"–0.002" final thickness as required by the application.

Step 04

Low-Temperature Cure

The coating is cured at controlled temperature to cross-link the binder system and drive out solvent. Final adhesion and lubricity are verified through standard test protocols.

Why Dry Film

Advantages of Dry Film Lubricant Coatings

Intermittent Lubrication

Provides dry lubrication through millions of cycles without replenishment — ideal for sealed assemblies and hard-to-access components.

Contamination-Free

Eliminates oil and grease contamination risk in clean-room, food processing, pharmaceutical, and medical device environments.

Thin & Precise

Thickness from 0.00025" enables use on tight-tolerance assemblies without dimensional interference or fit-up issues.

Chemical & Corrosion Resistance

Protects substrates from corrosion, chemical attack, and environmental exposure — extending service life beyond uncoated components.
