In the specialised fields of electroplating and anodising, achieving the perfect finish can feel more like an art than a science. Yet, simply by using the right masking products, it is possible to achieve a precise and consistent finish. Central to this are masking lacquers and thinners. In this article we’re taking a look at these fundamental tools for the electroplating and anodising processes, exploring their efficiency, versatility, and final results.
What Are Lacquers and Thinners?
Masking lacquer, often referred to as stop-off lacquer, is a specially formulated coating that can be applied to certain areas of a component. When it comes to electroplating or anodising that component, and as with any masking product, the coated areas will remain untouched by the plating process. This can be hugely useful for a wide range of uses, from working on complex technical devises such as computer chips within the aerospace industry, right the way through to cosmetic items such as jewellery.
Thinners, on the other hand, are solvents used to adjust of the viscosity of the lacquer. A masking lacquer that has been thinned will be easier to apply, especially in hard-to-reach areas or through spray systems.
The Benefits of Lacquers and Thinners
Precision Masking
One of the biggest advantages of masking or stop-off lacquer is the precision masking it offers. The selective application of coatings ensures that only specified areas are plated or anodised. This can be essential for components requiring detailed designs or when certain areas must remain free from coating to maintain functionality.
Quick Drying
Time is often of the essence in any manufacturing process, and the quick-drying nature of masking lacquer significantly reduces waiting periods. This drying time boosts efficiency, allowing for quicker progression to subsequent stages of production.
Temperature and Chemical Resistance
Masking products designed for the electroplating and anodising industry are formulated to withstand high temperatures and aggressive chemicals. This resistance is vital during the plating and anodising process, ensuring that the masked areas remain unaffected and the coating does not peel or flake away.
Application Flexibility
The viscosity of masking lacquers can be adjusted using thinners, which is particularly advantageous when applying the stop-off lacquer via spray systems. This flexibility ensures a uniform coat over the component, including hard-to-reach areas, and provides a consistent and reliable masking solution.
Easy Removal
Post-plating or anodising, the removal of the masking lacquer is a straightforward process, leaving the protected areas untouched and in their original state. This ease of removal is essential for maintaining the integrity of the component and for facilitating a clean, efficient workflow.
