Henkel’s Aerodag Ceramishield has been rebranded and is now under the company’s high profile Loctite brand. Now known as Loctite SF 7900 Ceramic Shield, this protective coating is formulated to actively repel welding spatter and the product is now widely available through Loctite surface treatment distribution channels so many more manufacturers can take advantage of its clear benefits.
This dry film is easy to apply, dries in seconds and adheres well to contact tips, shrouds, welding nozzles and jigs. It is sprayed directly onto degreased surfaces from an aerosol can, creating a ceramic coating that prevents adhesion of welding spatter for up to 8 hours without the need for re-application.
The use of Loctite SF (silicone-free) 7900 Ceramic Shield therefore minimises the downtime that is traditionally needed to remove spatter build up. Indeed, users report productivity gains of up to 10 per cent and a reduction in the cost of consumables by up to 70 per cent. After the shift, a gentle tap on the welding torch removes minor spatter build up and the equipment is then ready for a top-up coat. There is no need for expensive and environmental hazardous chemicals to release the spatter.
Another advantage of Loctite SF 7900 Ceramic Shield is that it provides both physical and thermal protection, both of which increase the service life of welding equipment. The quality of the weld seam is also enhanced as the shroud remains spatter free and the gas flow is not interrupted.
Laser and plasma cutting nozzles are particularly sensitive to spatter, so an application of Loctite SF 7900 Ceramic Shield is all that is needed to ensure the machining process is unimpaired. The coating also projects jigs, fixtures and fittings against spatter for up to a week and can equally be used on power cables, sensors and other metal components for the same purpose.
