Novec EGC-2702 surface modifier coating protects electronic components against moisture and corrosion - rapidly, economically and safely
3M launched Novec EGC-2702, a surface modifier coating that provides economic and fast protection against moisture and corrosion in electronics manufacture and assembly. A cost-effective high performance alternative to traditional conformal coatings, Novec EGC-2702 can be applied and dried within seven minutes, which is less than a third of the time of leading existing competitive products. It is also non-flammable and is designed to help electronics companies adhere to environmental, health and safety requirements.
Available exclusively in the UK and Ireland from distributor Acota, Novec EGC-2702 is aimed at electronics environments involving coating of sensitive components, such as circuit boards. Particular target markets include automotive, telecommunications, military and aerospace equipment.Novec EGC-2702 removes the need to mask surface areas - such as connection points - during the coating process, so time, labour and associated costs are substantially reduced. Novec EGC-2702 cures in just 40 minutes, which compares favourably with alternatives – for example acrylic, silicone and urethane-based coatings – which can take from 3 hours to one week to cure. Novec EGC-2702 can be cured at room temperature or with the aid of additional heat.
Once applied, Novec EGC-2702 forms a transparent layer of just one micron, yet is waterproof and repellent against aqueous solutions, oils and synthetic fluids, up to temperatures of 200 degrees Centigrade. In addition, future repairs can be carried out to the electronics component without the need to remove the coating.
Unlike most other coatings available, Novec EGC-2702 is non-flammable, which eliminates the need for electrical equipment used in the drying process to be classified as flameproof or ‘intrinsically safe’.
Due to the reduced drying and curing time, the volume of equipment and storage required is a third in comparison to conformal coatings: important in environments where floor space is often limited. This also helps to minimise energy consumption.
Novec EGC-2702 is a fluoropolymer dissolved in Novec 7200 hydrofluorether (HFE), developed by 3M, which is one of the world leaders in fluoro-based chemistry. Novec EGC-2072 is just one of a range of HFEs supplied by the company as part of its mission to provide manufacturers with speciality fluids designed to reduce the impact on the environment and conform with legislation. Novec EGC-2702 has zero ozone-depleting potential and has a high occupational exposure limit of 200 parts per million (PPM).
