Using additives to drive coefficient of friction and wear reduction in plasticsmolykotetl
Plastics are increasingly replacing metals in many applications, offering a cheaper yet reliable alternative. Yet material replacement can lead to new lubrication challenges. Presented for the first time at the Polytrib conference in Slovenia, we share exciting new experimental evidence on the effectiveness of additives in both external and internal application.
See experimental results and comparative evidence of Dow Corning® silicone additives, such as Dow Corning® HMB-1103, Dow Corning® 50-011 and Dow Corning® 31-441 pellets and powders. Tested in a range of polyamide (PA) and polyoxymethylene (POM) applications results are compared against commonly used compounds, such as PFTE.

New Silicone Copolymer Lubricants - the alternative to PFPE lubricationmolykotetl
Molykote’s groundbreaking Silicone Copolymer research provides a fit-for-purpose alternative to PFPE lubrication in low end applications. In a presentation at the 20th International Colloquium Tribolgy in January 2016, Molykote unveiled innovative new research into Silicone Copolymers set to revolutionise the lubrication industry. Using a unique combination of Phenyl and Fluoro Silicone groups Molykote has created a new class of lubricants with both high thermal stability and elevated wear resistance
Shown for the first time at the VII Moscow International Lubricant Week, Molykote® experts present a new range of lubricants developed through the use of unique patented technology.
New silicone copolymer lubricants combine the thermal stability of phenyl siloxanes with the wear resistance of fluoro siloxanes to deliver increased wear resistance even at high temperatures. The balance of phenyl and fluoro groups can be adjusted to produce the ideal solution for each tribological challenge.
With high-temperature lubricity achieved, without sacrificing low-temperature operation, these new oils and greases function effectively in a wide range of temperatures (-35°C to 220°C) – delivering superior performance against ester based lubricants. With a lower density than PFPE lubricants, they offer lower cost-per-use and their wide additive acceptance delivers additional properties such as corrosion and oxidation resistance.
See the results of the research and development along with a direct comparison against a range of silicone, PFPE and ester based lubricants.
A wide range of applications are emerging as we work with industry to launch further ranges within this group. Contact your Molykote representative now to request a development sample.
The new frontier in industrial lubricant research: the silicone copolymers.molykotetl
Think that silicone lubricants have reached their limitations? Think again. Siloxanes are sometimes dismissed due to their lower load bearing capacity, but new research from Molykote® from Dow Corning proves that altering the molecular structure of pendant groups can bring about a whole range of new properties, and applications, for the trusted silicone lubricant.
This presentation, made to the 83rd NLGI annual meeting in June 2016, provides a detailed overview of the research, development, benefits and applications of a new range of copolymer siloxanes.
Combining the excellent wear and friction protection properties of fluorosiloxanes with the high onset oxidation temperature afforded by phenylsiloxanes, the phenyl-fluoro copolymer makes use of both pendant groups, in varying ratios, to provide a range of lubricants each with their own application benefits.
The lubricants are fully compatible with additives offering further wear resistance, and the potential for a range of product substrates, such as greases.
Need a silicone lubricant with excellent metal-metal application? They are already here.

Introduction
• Modern passenger cars are equipped with sophisticated
measures to avoid propagation of noise from the engine
and gearboxes into the passenger compartment
• This creates a very comfortable environment for car
occupants
• On the other hand, this enables “new noises” to become
audible – particularly those generated by the sliding of
plastic components made of thermoplastics having poor
affinity under the tribological aspect

Application process
• Anti-friction coatings can
be applied with traditional
painting equipment
• For interior components,
the most established
process is spraying
2016 All Rights reserved
32. 32
Application process
• Process can be fully
automated (robot spraying)
– Adv. for parts of
complicated geometry
• Specific automatic plants
are available on the market

33. 33
Process integration
• Possible integration into existing production lines:
– Water-based system (no flash point, no emissions)
• Processability:
– Drying time: Water elimination; can be reduced to 2 min with 60°C
hot air; coated area touch dry
– Curing time: Fully cured after 2 hours (application of intended max.
load)
• Aspect after drying/curing:
– Dry film adhering to substrate
– Transparent if applied at recommended film thickness (10-12 µm)
– Dry film changes the gloss of the coated surface
– Not suitable for visible areas

Processability
• Spraying application
generally carried out
with 0.5 or 0.3 mm
nozzles
• Sedimentation/clogging
can be critical: High
stability is required
After 1 day After 6 months @ 40°C
