Electrolube, the leading manufacturer of specialist chemicals for the electronics, automotive, LED and industrial manufacturing industries, has announced that its innovative new 2K850 two-part, UV cure conformal coating has been selected as ‘SMT Technology Product of the Year’. This exciting new product was declared best in class for the Conformal Coatings category by the popular Indian electronics title, Electronics Maker, and was announced during India Electronics Week, held at the Bangalore International Exhibition Centre, 7-9th February.
This exciting new product combines the speed and convenience of UV cure, enabling an immediate tack-free coating, with the features and benefits of Electrolube’s revolutionary 2K conformal coating system; this innovative range combines the properties of a resin with the easy application of a coating. Once the two components are mixed, the system guarantees complete cure at room temperature within 24 hours, compared to the industry moisture cure average of about 8-14+ days.
Most single part UV cure systems require moisture to diffuse through the UV cured coating sections. If the material is a decent barrier to humidity, full moisture cure beneath components can be measured in weeks or even months for some components. For sensitive designs, the constant changes in material properties, as the moisture-cure process progresses can affect calibration. In a production scenario, this extended cure time can impact the amount of Work in Progress (WIP) and require excessive buffering. The 2K850 product offers major advantages over the first generation of single part UV cure coatings currently available. Current users of single part UV cure coating systems experiencing issues relating to their coating cracking during thermal shock, or extended moisture cure processes (or both) now have a robust alternative solution using their existing production equipment – the only additional requirement is a simple 2K fluid valve modification.
The 2K850 polyurethane system provides a much faster processing time with an advanced level of protection. The UL94V-0, IPC-CC-830C, MIL-I-46058C and IEC 61086 compliant coating features a wide operating temperature range of -40 to +130°C with excellent thermal shock performance and offers several other benefits over traditional UV cure conformal coatings. 2K850 is a tough, flexible, high performance coating, characterised by greater coating thickness (200-400μm), enhanced edge coverage and improved adhesion, hardness and scratch resistance. Ultimately, this coating provides a consistent and completely reliable chemical cure.
Electrolube’s 2K range, including 2K850 are all hydrophobic coatings, providing excellent water, moisture and condensation protection, including salt mist. This makes 2K850 an excellent choice for automotive, aerospace and other tough electronic applications exposed to harsh conditions.
Ron Jakeman, Electrolube’s managing director comments: “We are delighted that the 2K850 conformal coating has been selected for Best SMT Technology Product during IEW. Our manufacturing plant in Bangalore has seen exponential growth since we set up in 2016 and recognition of our products in this significant territory is a testament to the consistent drive for innovative solutions by our R&D team. The 2K850 really heralds a tremendous breakthrough for customers and is one example of how Electrolube is at the forefront of the industry, developing state-of-the-art electro-chemical solutions for electronics manufacturers.”
