Key points of the article
- A large South American mining facility was facing uneven wear and seizures in the pins of its SAG mill, causing downtime and high maintenance costs.
- The challenge was to find a lubricating paste capable of operating under extremely high loads, reducing friction and extending the life of the mechanical components.
- Molykote P-74, a high-performance paste based on MoS₂, was chosen for its effectiveness against wear, seizure, and metal-to-metal contact.
- The application led to an immediate improvement: greater durability of the couplings, stable lubrication, and reduced maintenance interventions.
- This case demonstrates the importance of relying on tested technical lubricants to ensure efficiency, operational continuity, and protection even in extreme conditions.
In the industrial sector, structural bonding is a critical phase that requires reliable, resistant solutions compatible with extreme operating conditions. A significant example is low-temperature environments, such as those typical of refrigeration systems, cold room components, or electronics for cold environments. In these contexts, choosing an acrylic adhesive capable of maintaining mechanical performance and thermal stability is not just a matter of performance: it is a guarantee of operational continuity.
With this objective, Permabond UV6357 was developed, a single-component UV-curing solution designed to offer reliability, flexibility, and sealing even in critical conditions.
Technical Characteristics of the UV6357 Adhesive
Permabond UV6357 is a highly reactive single-component acrylic adhesive that cures rapidly through UV light exposure. It was initially developed for a manufacturer of refrigerator and freezer components, where extreme thermal conditions severely test adhesive joints.
The product has been optimized to ensure:
- High thermal resistance, especially at low temperatures
- Excellent adhesion on glass, metal, and rigid plastics (such as ABS, PVC, and Nylon)
- Resistance to thermal shocks and cooling/heating cycles
- Very high elongation at break, to prevent cracking and detachment
- Flexibility and impact resistance, even after prolonged curing
- Good resistance to detergents and industrial cleaning cycles
These characteristics make it ideal for applications in refrigerated environments or exposed to thermal excursions, with stable and long-lasting performance.
Adhesive for Refrigerators and beyond: Strategic Applications
Permabond UV6357 is successfully used in a variety of applications in highly specialized sectors. In addition to being an excellent adhesive for refrigerators, it is used in:
- Shelves and compartments of fridges and freezers
- Handles for doors and hatches
- LED lighting for cold rooms
- Electronic displays and touchscreens
- Optical scanners and transparent plastic components
- Rear windows of industrial vehicles
- Double-glazed windows for thermal insulation
In all these applications, the UV6357 acrylic adhesive demonstrates superior versatility, allowing for invisible, strong, and quick bonding without compromising aesthetics or functionality.
An Ally in Production Processes
Being a single-component acrylic adhesive, UV6357 does not require mixing or preparation: simply apply it and expose it to UV light for controlled, rapid, and repeatable curing. This feature is particularly advantageous in automated processes and environments where cycle time is a critical parameter.
