What is dry film coating?
Dry-film lubricants are materials that are used to reduce the friction between two mating surfaces that slide against each other without the need for oils and greases.
What is DFL coating?
Dry-film lube (DFL) is a coating that is applied to the strip surface via a coil coating operation. They are used in stamping or forming operations as is without the use of any additional drawing oil or compound. Acrylic DFLs are the most commonly used for severe drawing applications such as stainless steels.
What is PTFE in lubricants?
PTFE stands for Polytetrafluoroethylene. This is a Fluoropolymer used widely in industrial applications. Due to its many properties, PTFE lubricant is what we commonly know as the non-stick coating used for cookware. This discovery was made accidentally in 1938 by an engineer from the DuPont organisation.
What is lubricant coating?
Dry lubricating films containing solid lubricants. Dry Film Lubricants. Applying a Lubrication Coating Over Sliding Surfaces of Parts Reduces Friction and Wear. Dry film lubricants formulated with solid lubricants, such as molybdenum disulfide(MoS2), PTFE and graphite, and binders.
What is Dry PTFE?
DRY PTFE Spray is a non-toxic, non-staining dry PTFE lubricant, ideal for use in environments where wet lubricants cannot be tolerated, e.g. dusty environments such as paper mills and bakeries. Manufactured by ROCOL and available to buy online today.
How does dry film lubricant work?
Dry film lubricant coatings will lower the coefficient of friction of your design (static/dynamic), reduce force relating to speed and load, and allow more consistent motion. Dry film lubricants work at elevated temperatures, making them safer than using wet lubricant oils or grease.
What is molybdenum coating?
What exactly is an MoS2 Coating? An MoS2 coating is a dry film lubricant that works by intrinsic slippage of the sulfur atoms (weak Van der Waals forces). This helps reduce wear on the parts and improve coefficient of friction. The coating is made up of high purity molybdenum disulfide powder.
Why is graphite used as a dry lubricant?
The carbon atoms are strongly bonded together in sheets. Because the bonds between the sheets are weak, graphite shows lower shearing strength under friction force. Thus it can be used as a solid lubricant and has become one of traditional and primary solid lubrication materials.
Is Teflon stronger than PVC?
Teflon has better heat resistance. The rated temperature of Teflon wire can be between 105-250 degrees, while the rated temperature of PVC wire is generally between 60-105 degrees. For example: if it is a military product, it is generally required that the product can work normally in an environment of 65 degrees.
