Global electro-chemicals specialist, Electrolube, is selectively partnering with key dispensing equipment manufacturers (including PVA, Nordson Asymtek and others) to ensure that its 2K conformal coatings enable customers to obtain optimum results from this innovative range of two-part coating systems. Electrolube’s revolutionary systems are specifically designed to combine the protection and properties of a resin with the straightforward application of a conformal coating without the use of harmful solvents.
While Electrolube’s innovative two-part (2K) conformal coatings continue to receive wide acclaim from the electronics industry, customers frequently enquire about the dispensing process, with questions such as: “How do I actually apply these revolutionary coatings – does it involve a large capital outlay – where do I start in order to source some suitable dispensing parts?”
Throughout the development of the 2K range, Electrolube has worked closely with selective coating machine manufacturers to ensure that formulations are optimised for application using commercially available dispensers. Included among these is PVA's two-component spray valve VPX-2KS, which has proved successful with Electrolube's 2K500 - a two-part polyurethane conformal coating system that provides a wide operating temperature, maintains clarity after prolonged exposure to UV light, as well as excellent thermal shock and abrasion resistance.
Electrolube’s conformal coatings team, comprising of Jade Bridges, Joel Shenton and Phil Kinner, Electrolube’s Technical Director of the coatings division, recently joined PVA’s Shane Plasse and Matt Lilla at PVA’s headquarters in Boston, USA, to further improve and refine the 2K application process.
At one point during this technical collaboration, an opportunity arose to test a new process for a customer who needed to apply a 2K coating of just 70µm thickness. This is considerably thinner than the recommended 200µm for 2K coatings and was dictated by the 100µm clearance between the board and its housing.
