Electrolube launch new conformal coatings at SMT Hybrid Packaging

Electrolube, the global manufacturer of specialist electro-chemicals for the automotive, electronics, LED and industrial manufacturing industries, will launch a series of innovative new polyurethane and silicone conformal coating products at this year’s SMT Hybrid Packaging exhibition, which takes place on the 5th-7th June in Nuremberg. Electrolube’s senior technical team, will be available to advise visitors of suitable conformal coating, encapsulation resin and thermal management solutions in Hall 4, Stand 548.

Electrolube’s 2K, two-part conformal coating range has been an important advancement for customers, combining the tough, resistant properties of an encapsulation resin, with the easy application of a coating. The company has extended the range with the new 2K550, 2K850 and 2K750 conformal coatings.

2K550 is a tough, flexible, high performance coating, which has excellent clarity and resistance to discolouration, humidity and condensation. The UL94V-0 compliant polyurethane coating is characterised by greater coating thickness and enhanced edge coverage and shows improved adhesion, hardness and scratch resistance. 2K550 also features a fluorescent trace to aid inspection.

The new 2K850 two-part, UV cure coating combines the speed and convenience of UV cure with the benefits of Electrolube’s 2K system, merging the properties of a resin with the easy application of a coating. The 2K850 offers a faster processing time while still delivering superb levels of protection. The polyurethane coating is a groundbreaking new product, providing an immediate tack-free coating and enabling complete cure at room temperature within 24 hours, compared to the industry moisture cure average of 8–14 days. Featuring a wide operating temperature range of -40 to +130°C, with good thermal shock performance. 2K850 provides a consistent chemical cure and excellent protection against water, moisture, salt mist and condensation, making it ideal for tough electronic applications exposed to harsh conditions.

Due to increasing demand, Electrolube has also developed a new silicone 2K conformal coating, 2K750. The UL94V-0 compliant coating provides a wide operating temperature range of -40 to +220°C, with a high continuous use temperature of 200°C. The tough, low-stress coating has an extremely fast thermal cure time of 10 mins at 80°C, in addition to curing at ambient temperature, and provides excellent adhesion to most solder resists and metals. The transition to implementing Electrolube’s 2K conformal coatings range couldn’t be simpler with a straightforward valve modification such as PVA’s VPX-2KS or Nordson Asymtek’s AM range.

Additional new silicone coating products on show include MCS and HCS. The new Moisture Cure Silicone (MCS) coating is a soft, flexible, low stress coating with a wide operating temperature range (-40 to +200°C) and a high continuous use temperature of 180°C. The low viscosity, solvent-free silicone material provides a rapid touch-dry time at ambient conditions (10 mins at 25°C, 50 per cent RH), which can be further accelerated with heat, and fully cures within 48 hours.

The new, low-viscosity Heat Cure Silicone (HCS) coating offers an extremely fast full thermal cure time of 10-12 mins at 110°C. The low odour, solvent-free coating meets the requirements of UL94V-0 and has virtually no cure by-products. Developed with improved adhesion, HCS is a soft, yet tough, low stress coating with a wide operating temperature range (-40 to +200°C) and a high continuous use temperature of 180°C.

Electrolube managing director, Ron Jakeman, comments: “Electrolube is increasingly becoming the go-to resource for specialist electro-chemical solutions that solve customers’ manufacturing problems and help them bring high-quality, reliable products to market faster. Our key focus for SMT will be to further endorse our position as a major player in the European market and highlight our expertise as a complete solutions provider in conformal coatings, encapsulation resins and thermal management solutions. We are looking forward to meeting visitors during the event, to learn about their requirements and help advise them on the efficient solutions we offer.”
