Bio-based wash primer expands validation on industrial carbon steels

The growing need to replace chromated primers used in steel corrosion protection has driven the development of safer and more sustainable alternatives. BIO FLAV PRIMER, a bio-based wash primer developed from valorized agro-industrial byproducts offers an alternative to conventional primers formulated with zinc tetroxychromate, eliminating the use of chromated compounds and combining high corrosion protection with a nontoxic, biodegradable, and environmentally friendly formulation.

The protection mechanism is based on the interaction of natural compounds with the metal surface, where they form a molecular network of chelates capable of stabilizing existing corrosion products and generating a continuous, adherent, and non-porous organic film. This passivating interfacial layer stabilizes the substrate and provides an excellent base for the adhesion of subsequent coatings.

Developed by BIOFLAV Ingenieria de Superficies, comparative studies of the primer conducted on SAE 1010 steel demonstrated superior performance compared to the benchmark commercial wash primer formulated with zinc tetroxychromate, achieving 92% corrosion protection efficiency under the evaluated conditions. While the chromated primer relies on active pigments that are progressively consumed during service, the organic film developed by BIO FLAV PRIMER maintained highly stable electrochemical behavior throughout the evaluation period.

As part of the current technological validation stage, prior to pre-pilot and pilot scale-up, the development is extending its evaluation to other carbon steels of industrial interest. For this purpose, an oil drilling rod made of SAE 4140 carbon steel, discarded after a failure mechanism in service and exhibiting significant surface deterioration, is being used. The use of a recovered industrial component previously subjected to severe operating conditions allows for the evaluation of the coating’s performance in a representative service scenario, providing evidence for the subsequent stages of technological scale-up and its future industrial and infrastructure implementation.

Gore gains FDA approval for first deep venous stent indicated for the IVC and iliofemoral veins

W. L. Gore & Associates, Newark, Delaware, announced on January 6, 2026 that the U.S. Food and Drug Administration has approved the GORE VIABAHN FORTEGRA Venous Stent for the treatment of deep venous disease in the inferior vena cava (IVC), iliac, and iliofemoral veins. The device is the first stent approved in the United States for the IVC and iliofemoral indication, and previously received FDA Breakthrough Device designation.

The FORTEGRA Venous Stent (formerly the GORE VIAFORT Vascular Stent) consists of an open-structure, self-expanding wire-wound nitinol frame and an expanded polytetrafluoroethylene (ePTFE) polymer lattice. The combination is designed to balance conformability to the natural venous anatomy with compression resistance throughout the entire device length, while the wound nitinol architecture supports fracture resistance under the dynamic mechanical loading characteristic of large-vein anatomy.

Approval was supported by an international pivotal trial that evaluated 89 patients with deep venous disease across the IVC, iliac, and iliofemoral veins. The device met its primary safety and effectiveness endpoints and demonstrated patency, freedom from clinically driven reintervention, and safety performance consistent with a first-line venous stent indication.

W. L. Gore & Associates is a privately held global manufacturing company founded in 1958 and headquartered in Newark, Delaware. Its medical products division supplies cardiovascular, vascular, structural heart, and surgical solutions in more than 50 countries and has served the deep venous disease space through prior peripheral and arteriovenous platforms.

One Minute Mentor: Austenitizing of Water-Hardening Tool Steels

Austenitizing temperatures for water-hardening tool steels normally vary from 760 to 845 °C (1400 to 1550 °F), as indicated in Table 2. Higher temperatures are sometimes used for special purposes (Fig. 2). Hardenability increases as austenitizing temperature increases. The optimum time at austenitizing temperature is from 10 to 30 min. Preheating is unusual except for very large tools or those with intricate cross sections. It is particularly important to protect shallow-hardening steels against scaling and decarburization. Severe scaling can interfere with heat transfer during quenching and slow the required high rate of cooling. Decarburization will produce a soft surface on any tool steel, but in a deep-hardening steel it can be ground off until the underlying hard high-carbon area is reached. Grinding a shallow-hardening steel will frequently expose the soft core.

Confluent Medical Debuts Filmcast Select for Tailored Polymer Tubing Performance

Confluent Medical Technologies, Chattanooga, Tennessee, announced the launch of Filmcast Select, a materials customization program that enables medical device OEMs to tailor key performance attributes of Filmcast PTFE and polyimide tubing for specific applications.

The program addresses a growing challenge in minimally invasive device design: as procedures advance and devices become smaller and more complex, the traditional one-size-fits-all approach to polymer tubing is no longer sufficient. Filmcast Select allows customers to select tubing based on the characteristics that matter most, including flexibility, strength, durability, surface finish, and optical clarity.

The program includes several specialized PTFE options: FlexaCast for increased flexibility and elongation, DuraCast for enhanced abrasion resistance, and UltraCast for higher tensile strength in demanding applications. Confluent can also work with customer-preferred PTFE dispersions, allowing OEMs to leverage existing biocompatibility data and reduce development time.

Confluent Medical Technologies is a global leader in the design and manufacture of medical devices and components, specializing in nitinol, polymer, and catheter-based technologies.

One Minute Mentor: Mechanical Shock

Mechanical shock is sometimes used to stabilize tool steels. One method of producing shock is to suspend the part so that it hangs freely and then strike it with a wooden hammer. This is believed to set up elastic waves which add to the magnitude of the residual stress imparted by the previous heat treatment. At locations where the resultant magnitude of stress exceeds the elastic limit, plastic flow should occur and result in stress relief. This would be manifest by higher dimensional stability. A shock treatment should not be considered as a substitute for a thermal method of stabilization but rather as an auxiliary method which enhances stabilization.

Dimensional changes in W1 steel resulting from dropping on a concrete floor as determined by Fletcher (are shown in Fig. 6. The untempered specimens showed greater dimensional changes than the tempered specimens due to the higher level of residual stress in the untempered condition.
