II. Technical FAQs

What is corrosion?

Corrosion is the chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties. Usually corrosion is the oxidation of metals in the presence of water or water vapor, and is known as rust (iron, steel) white rust (galvanized steel), and other terms of corrosion failures such as tarnish, pitting and flaking.

How does the Product prevent corrosion?

The Product prevent corrosion in several ways:

  1. From outside, by acting as a protective barrier from external corrosive atmospheric elements such as abrasion, water, dirt, and acid gas pollutants. The Anti-UV membrane has good weatherbility, can shut out water and air that will lead to corrosion of metal surface.
  2. From inside, the primer coat has good waterproofing performance, settles on metal surfaces and inhibits rust advance by permeating rust layer because it is oil type.

 Can the Product protect those structure/parts that are already corroded?

Definitely, once the Product is wrapped onto the already-corroded steel structures, from the inside, the primer coat will inhibit rust advance by permeating rust layer because it is oil type, and from the outside, the Anti-UV membrane can, with good weatherbility, shut out water and air that will lead to corrosion of metal surface.

For better and long-term protection, it is recommended to protect the “susceptible to corrosion” steel structures right after it is constructed for long-life trouble-free operation.

Can the Product be used for complex shape strucutres/items like flanges, bolts, nuts, valves, connectors, uneven surfaces?

Yes. The Product set has Nitohullmac XG, which is clay-like filler material added inert inorganic fillers and thickener etc to liquid rubber and is a supplementary material to be used when putting or winding anti-corrosion tape, can be used as gap filler materials for irregular shaped parts like flange or valve. It has good workability, hard to change the hardness at high or low temp, can keep it molded even at high temp

 Does the topcoat has waterproofing function?

Yes. Once dried, the topcoat shall form a thing membrane that will increase surface strength with reinforce materials like cheesecloth. It can reduce stickiness of XG tape after application, and improve outside appearance, durability and waterproofing performance for XG tape.

 Are there any inhalation or contact risks with the Product?

The Product is safe. Please refer to the respective MSDS.

What is the best way to store the Product before use?

Keep the Product in original packaging until use. Store in a dry, covered warehouse at room temperature.
