Henkel Offers Electro-ceramic Coatings for Various Engine & Exhaust System of Powertrain

Published on 2013-04-24. Author : SpecialChem

Aimed at meeting the ever-increasing requirements on automotive efficiency, performance and service life, Henkel has developed an array of innovative product solutions covering the full range of powertrain manufacturing processes. Henkel's presence at "Engine Expo 2013" - Europe's leading international trade fair for engine technologies, taking place from June 4 to June 6 at Stand 3610 in Stuttgart, Germany - will focus on a range of multifunctional surface treatment solutions, adhesives and sealants designed to contribute to the optimization of assembly processes.

With its unique combination of innovative products and process know-how, Henkel not only contributes to the smooth and cost-efficient production of powertrain components but also helps enhance durability, safety and sustainability through compliance with the highest of quality standards. Henkel has solutions supporting every step along the value chain: Cleaning, cooling and lubrication during the manufacture of powertrain components, plus surface treatment, bonding and sealing at the assembly stage. Henkel - world market leader for adhesive technologies - thus plays a significant role in shaping trends in the automotive industry. Worthy of particular mention in this respect is the growing importance of lightweight construction technologies and the constant need to reduce emissions and fuel consumption.

Multifunctional electro-ceramic coatings

Under the brands Loctite and Bonderite, Henkel is able to offer a select range of electro-ceramic coatings (ECC) for various engines and exhaust system applications. Suitable for aluminum, titanium, magnesium and their alloys, these coatings enable such metals to be used in the manufacture of light constructions that would normally require steel, thus greatly reducing vehicle weight. With beneficial tribological properties leading in particular to reduced wear, Henkel's electro-ceramic coatings also contribute significantly to increasing engine component efficiency and saving fuel. Tests also show that ECC helps reduce harmful engine emissions by diminishing the quantity of nitrogen oxides produced during fuel combustion. Further, diesel engines are found to be less noisy, thus meeting the ever present need for quieter vehicles. Henkel's electro ceramic coatings further combine outstanding corrosion protection with high resistance to extreme thermal loading, satisfying the prime prerequisites for, say, exhaust system and turbocharger component longevity.

ECC also delivers top performance for Porsche Motorsport, with which Henkel has a mutually beneficial collaboration agreement. Henkel is committed to supporting this partner not only as an official Porsche Mobil 1 Supercup sponsor but also through heavy involvement in Porsche's product development activities. Henkel products are therefore regularly tested by Porsche under the extreme conditions that only motor sport can provide.

Innovative liquid gasketing portfolio

Gaskets are incorporated in powertrain components to prevent gas and liquid leakage. Aside from its liquid gasketing products, based on anaerobic-curing specialty products and silicones and used primarily for engine components, Henkel has also now developed a range of innovative polyacrylate gasketing systems. These Loctite products offer exceptional resistance to aggressive transmission oils and axle lubes and can therefore be relied upon to durably seal flanges and similar connections on transmission cases, differentials and axles. The new technology exhibits up to a nine-fold reduction in volatile organic compound vapor permeability compared to conventional gaskets. In addition, polyacrylate-based liquid gaskets offer the advantages of not affecting the foaming behavior of transmission and axle lubricants, and of being paint-coatable.

Reliable porosity sealants for drive components

Porosity - and the possibility of leakage - is always a concern when it comes to the casting of cylinder blocks, cylinder heads, transmission cases and similar from light metal alloys. However, such problems can be quickly and reliably avoided by having Henkel seal these components. For this, the components are sent to special service centers where - in a fully automatic process - they are impregnated under vacuum with a Loctite resin, so sealing the pores and avoiding scrap. This certified process is already in operation at many renowned automobile manufacturers and component suppliers.
