One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

SPIROL Press-N-Lok™ Pin for plastic housings

The Press-N-Lok™ Pin was designed to permanently retain two plastic components to each other. As the pin is inserted, the plastic backfills into the area around the two opposing barbs, resulting in maximum retention. Assembly time is quicker, and it requires lower assembly equipment costs compared to screws and adhesives -- just Press-N-Lok™!

Load fasteners with integrated RFID

A crane, rope, or chain may be required when something needs lifting -- plus anchoring points on the load. JW Winco offers a wide range of solutions to fasten the load securely, including: lifting eye bolts and rings (with or without rotation), eye rings with ball bearings, threaded lifting pins, shackles, lifting points for welding, and more. Some, such as the GN 581 Safety Swivel Lifting Eye Bolts, even have integrated RFID tags to clearly identify specific lifting points during wear and safety inspections and manage them digitally and without system interruption.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted. Ideal for unidirectional continuous movement or rapid bidirectional motion.

What is 3D-MID? Molded parts with integrated electronics from HARTING

3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single, 3D component. It replaces the traditional printed circuit board and opens up many new opportunities. It takes injection-molded parts and uses laser-direct structuring to etch areas of conductor structures, which are filled with a copper plating process to create very precise electronic circuits. HARTING, the technology's developer, says it's "Like a PCB, but 3D." Tons of possibilities.

Special new Navy Research Lab-developed single-component topcoat applied on entire freeboard of Navy ship

Port-side view of USS Essex (LHD 2) after full application of an NRL-developed 1K polysiloxane topcoat in 2017. The Essex's entire freeboard, approximately 105,000 sq ft, was covered with 320 gal in about four weeks. NRL's patented 1K topcoat has demonstrated better exterior durability compared to legacy surface ship coatings.

 

 

 

 

Recently, a novel coating developed by researchers at the U.S. Naval Research Laboratory (NRL) for the exterior topsides of Navy surface ships went beyond small area testing to covering the entire freeboard of an amphibious assault ship.

Until April of 2017, NRL's single-component (1K) polysiloxane coating had only been tested on 400- to 800-sq-ft areas of ships due to limited production quantities and the typical size of topside paint repairs conducted by their crews.

However, based on positive Sailor feedback, and the 1K coating's outperformance of existing coatings with regard to color and gloss retention in sunlight, Sailors from the USS Essex (LHD-2) requested that larger quantities of the 1K polysiloxane coating be produced to paint the entire freeboard, approximately 105,000 sq ft.

Painting with 1K also helped return the ship to its required semi-gloss, haze gray camouflage appearance.

Dr. Erick Iezzi of NRL's Chemistry Division is the principal investigator and inventor of the 1K technology.

"The Navy was in need of a better solution for all the topside painting performed by Sailors on surface ships," Iezzi said. "The 1K is advantageous in that it provides greater than five times the retention of visual camouflage and better resistance to shipboard contaminants, such as running rust and soot, than the legacy silicone alkyds, which should reduce future costs to the Navy by eliminating the need to overcoat the latter every 9 to 12 months as a result of discoloration and staining."

The application on the freeboard of the USS Essex was performed entirely by Sailors, consumed more than 300 gal of the 1K polysiloxane, and took about 4 weeks to complete.

Single-component refers to an all-in-one-can system that does not require the measuring and mixing of two or more components before application, thus providing a "user-friendly" system for Sailors when applying on ships.

"The 1K polysiloxane is easy to use. There is no mixing, surface preparation is easy, and it covers well," said Lt. j.g. Donald Ham, Essex's Assistant Deck Department Head. "We painted our entire hull with approximately 320 gallons of the 1K, whereas it would have taken greater quantities of qualified two-component (2K) polysiloxanes. Thus, we not only saved time, but we saved money. The best part is that the 1K polysiloxane rolls on the ship just like the legacy silicone alkyds."

Funding for development, optimization, and transition of the technology was provided by the Naval Sea Systems (NAVSEA) Command.

"The 1K polysiloxane coating has tremendous potential," said Mark Lattner, manager for the NAVSEA Paint Center of Excellence program. "If the application on the USS Essex performs as expected, our Sailors will be empowered with an advanced coating technology that is robust, easy to use, and will yield significant cost avoidance."

NRL representatives and NAVSEA Corrosion Control Assistance Team (CCAT) members oversaw the application on the USS Essex and documented all aspects of the application. The performance of the 1K polysiloxane on the USS Essex will be monitored for several years, although the coating is estimated to be on the Qualified Products Database (QPD) this year. The 1K polysiloxane is expected to save the Navy several million dollars annually once fully implemented.

The patented technology, U.S. 9139753, has been licensed to coating manufacturer NCP Coatings (Niles, MI) for optimization and scale-up. Testing to the Navy's MIL-PRF-24635, Type V (high-durability) topside performance requirements was supervised by James Tagert of NRL's Chemistry Division.

"Our initial focus has been on coatings for the Navy, but we do intend to commercialize this technology starting with the Industrial OEM," said Randy Terrill, VP Technology & Quality, NCP Coatings. "The coating has potential in markets ranging from high-performance trailers to aerospace. The product designed for the Navy can be applied by brush, roll, or spray and can be modified for specific application equipment to provide the desired appearance. The SiloxoShield 1K Siloxane is a one-component coating that is isocyanate-free with chemical resistance and weathering performance similar to two component polyurethanes."
