透明烤漆搪瓷是金属（尤其是铝和镁）的保护性涂料之一，因此，英国镁的主要供应商Magnesium Elektron推荐使用。

在需要对铝，钢，钛和镁进行Zui大保护的地方使用。提供透明涂层，以保护船舶免受海洋和其他恶劣环境的影响，包括需要对工业溶剂，油和液压油具有高度化学耐性的应用。

经过专门配制以提供产品性能，该产品具有透明，低气味和高闪蒸的特性，因此非常适合浸渍罐和喷涂。

还发现该产品不仅抗重铬化，而且抗HAE重度阳极氧化。这对于在镁上进行后加工以提供Zui大的保护很有用。

该产品于1995年2月由卢卡斯·西方公司（Lucas Western）批准用于BRR 710变速箱，由于对重阳极氧化具有抵抗力，因此引起了人们的关注，这意味着整个铸件都可以采用机械加工的Rockhard进行涂层，并采用Rockhard进行涂层“Rockhard clear stoving enamel is one of the best protective coatings for metals, particularly Aluminium and Magnesium and as such is recommended by Magnesium Elektron, the leading suppliers of Magnesium in the UK.

Used where maximum protection is needed on Aluminium, Steel, Titanium and Magnesium. Provides a Clear coat for protection against marine and other harsh environments including applications where a high level of chemical resistance to industrial solvents, oils and hydraulic fluids is necessary.

Specifically formulated to give optimum product performance this product is crystal clear, low odour and high flash making it ideal for dip tanks as well as spraying.

This product has also been found to be resistant not only to re-chromating, but also to HAE heavy anodising. This is useful for post machining on magnesium for maximum protection.

Approved in February 1995 by Lucas Western for use on the BRR 710 gearbox, this product caused interest due to resistance to heavy re-anodising, which means that whole castings can be coated with Rockhard machined and recoated with Rockhard.
