Inorganic Zinc Paint

This is an important difference between the two materials and is the reason why under many difficult corrosion conditions the inorganic zinc coating will.

Inorganic zinc paint. Corrosion of steel is caused by water oxygen and ions present in abundance in our atmosphere diagrammatic representation of an inorganic zinc silicate coating on steel zinc corrosion products are trapped within the glassy matrix forming a layer that prevents further oxidation. Inorganic zinc rich paints which adhere to the steel with mild chemical reactivity have good solvent resistance and can withstand temperature up to about 700 f 375 c. The zinc pigments comply with astm d520 type ii zinc dust. Designed for use over prepared blasted steel in a variety of industrial areas zinc clad ii es contains 85 by weight of zinc dust in the dry film.

As the name implies this type of coating has large amounts of zinc metallic dust mixed with a binder. On the other hand zinc in galvanizing is pure zinc and any acid in the atmosphere reacts directly with it with no inhibition of the reaction as in the case in the inorganic zinc coating. Part of the interzinc 22 series interzinc 2280 is a two component solvent based silicate inorganic zinc rich primer 80 suitable for use with a wide range of high performance anticorrosive systems and topcoats in both maintenance and new construction. Barrier 90 conforms to the compositional requirements of sspc paint 20 level 1 and iso 12944 iso 20340 bs 4652 bs 5493 as nsz 3750 9 1994.

Inorganic zinc rich coatings generally consist of a silicate binder whereas organic zinc rich coatings can use a wide array of binders including epoxy polyurethane and alkyd etc. Inorganic zinc coatings provide excellent anti rust corrosion protection when used in chemical plants refineries and coastal or offshore installations. An inorganic zinc coatings is a type of coating that possess the distinct ability to give corrosion protection to surfaces such as steels. A two component solvent based inorganic ethyl silicate zinc rich coating.

Inorganic zinc coatings is compatible with epoxies phenolics acrylics silicones and many other coatings. Inorganic zinc rich paints do not chalk peel or blister readily are easy to weld and provide simpler cleanup than organics. The type of zinc rich coating is defined by the binder that is used during the formulation and manufacturing of the coating.
