Silicone anti-corrosion coatings formulated to restore metal structures and equipment on an advanced level


Corrosion is a serious concern in the utilities industry, where outdoor conditions accelerate the spread of rust. Power plants, distribution lines and substations are built under harsh weather conditions and temperatures, to which where metals such as steel and aluminium are exposed.

Research by NACE International, worldwide corrosion authority, demonstrated, that the annual cost of this problem comes to a total of $2.5 trillion which means corrosion in utilities makes up for the larger part of annual industrial corrosion costs, namely 39.7%.


To tackle this problematic, at Midsun Group, we have formulated a ready-to-use one-part system RTV coating, named Midsun Silprocoat to protect against corrosion and to optimize the usage of the equipment.


The product can be sprayed immediately after opening the pail. No primer is needed, and minimum surface preparation is required.


Moreover, the product cures in less than 1 hour and will last more than 10 years in challenging environments. 


Midsun Silprocoat is a top-notch resistance to weathering, water and chemical substances – making it ideal to use in coastal, industrial and desert areas. 

  • Extreme heat resistance (up to 160°C) 

  • Ideal to enclose lead paint

  • Optimal corrosion protection (e.g. power system equipment, metal hardware and structures, oil and gas storage tanks, pipes and metal barriers)

  • Strong adhesion

  • Anti-aging, offering a long-term solution

  • Available in VOC compliant formulations

  • High UV light resistance


In comparison to other products with self-priming solutions, the one-part silicone elastomer coating is known for its extreme durability under all circumstances, making it the perfect product to mitigate corrosion.  


*Properties Cured at standard conditions for 7 days


Prior to coating, the surface must be thoroughly cleaned. In most instances, the surface only requires a high-pressure water wash. Tightly bonded tenacious rust does not need to be removed, but, however, depending on the amount of corrosion present, solvent cleaning (SSPC-SP1), hand tool cleaning (SSPC-SP@), power tool cleaning (SSPPC-SP#) or commercial blasting (SSPC-SP6) may be required. Please contact your Midsun Group representatives for the recommended surface preparation.

Methods of coating insulators include brushing, rolling, and spraying. When a small surface needs to be coated, coating by aerosol cans is sufficient to use, preferably applied with a brush or roller is recommended method.

Usually one or two coats is sufficient to obtain the recommended minimum thickness of 10 mil 250 microns (0.010”). When coating a large structure surface, spraying is the recommended approach. 

Each coat can be applied as soon as the previous coat becomes tacky (not entirely dry!). This can be anywhere up to 15 minutes, depending on the ambient temperature and humidity. The full curing time is approximately 45 minutes.

* Standard Conditions are 25°C (77°F) and 50% relative humidity
