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.

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.
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

How to reduce hot forging costs through innovative techniques?Srikar Shenoy
This presentation gives successful industrial case studies of cost reduction in hot forging by the use of:
1. Anti-scale protective coatings to prevent rejections due to scaling, reduce or eliminate shot blasting, reduce decarburization in heat treatment, hot rolling and hot forging.
2. Environment friendly die lubricants that eliminate pollution and increase die life.
3. Zero maintenance die lubricant spraying systems that ensure maximum uptime and no unplanned downtime during hot forging.

An ideal flanged joint would consist of two, mirror-finish, perfectly flat
and parallel surfaces bolted directly together to create a leak-free seal.
However, manufacturing processes do not allow for perfect sealing surfaces.
Most flange faces have surface irregularities that cannot be sealed without
the use of some type of compressible, resilient material or a combination of
materials between them to seal the fluid being transferred. This is true
even for the most finely machined surfaces as a turbine flange where the
surface asperities can create a leak situation.
Project Sales Corp presents an exhaustive range of sealing and gasketing
material that can be used to effectively seal flanges and in many cases seal
leaks that can develop in operation and can be sealed in-situ without an
outage of the equipment. We stock gasketing compounds, jointing Compounds,
Flange Sealants, Thread Sealants, Pipe Sealants, Form-in-place RTVs, Turbine
Flange Sealing Compounds. Please see attached presentation for more details.

The flooring is most operational part of any Industrial, Commercial, Residential or Institutional buildings. The floor is heavily exposed to physical and chemical abuses, load due to traffic of forklift & trolleys, abrasion due to mechanical wear, stress, chemical resistance to spillages from occasional to continuous immersion, temperature, snow, ice melting chemicals such as rock salt, slip resistance, impact resistance, fire resistance, conductivity, aesthetics, rapid curing , anti-bacterial and permeability to liquids. In this high demanding industrial environment, concrete surface fails. Also concrete substrate is porous in nature thus when water and other fluids enter into concrete, the reinforcing steel corrodes. To sustain and maintain the industrial floor a protection is must.
Monarch's FloorClad Screeds & Toppings offers seamless high performance flooring systems to enhance floor design life and for the ultimate convenience of easy to clean surface with increased resistance to liquid penetration. The toughness and durability of the hygienic coating along with choice of attractive colors suits to variety of environmental conditions. The coated decorative surface presents ideal and pleasant working atmosphere resulting in productivity improvement.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
