This document provides information on Zinc Anode 304 MZS, an inorganic zinc silicate coating for protecting steel against corrosion. It is a two-part coating that is solvent-based and self-curing. It provides excellent cathodic protection and forms an abrasion-resistant film. It can be used in both coastal and industrial environments and has good resistance to acids, alkalis, solvents, salt, and water. The coating attains water resistance within 30 minutes and is unaffected by rain, condensation or dew. Surface preparation involves blast cleaning to Sa 2.5 and the coating can be applied by conventional or airless spray.

Zinc Anode 304 MZS Inorganic Zinc Silicate Coating SURFACE PREPARATION
Remove grease, oil and other contaminants and blast clean to a minimumm of Sa 2.5 Swedish Standard SIS 05 5900 with a surface profile not exceeding 35-40 microns.
The surface should be clean and dry before application of Zinc Anode 304 MZS
APPLICATION
Stir Part A thoroughly to uniform consistency. Mix the components in the recommended proportion with constant stirring preferably with a mechanical stirrer. Continue stirring until the components are thoroughly mixed. Strain the mixture through a 80 mesh sieve. Allow the mixture to mature for 15-20 minutes before application. Stir again before use and continuously during application. Conventional Spray: Add upto 10% Thinner 870 depending on conditions. Use any standard pressure pot equipment at an atomising pressure of 3.5-4.4 kg/cm2 Airless Spray : Apply preferably without thinning. However, add upto 10% Thinner 870 depending on conditions. Use any standard equipment having pump ratio 30 : 1. Tip size 0.38 – 0.48 mm. Tip pressure 110 –160 Kg/cm2.

Lumeros HR/47 or Lumeros HR/47 or Steel Zinc Anode 304 MZS Silicone Acrylic HB Silicone Acrylic HR Ctg Coating Overcoating of Zinc Anode 304 MZS: The surface must be fully cured and free from residual solvent prior to overcoating. This normally takes 10-12 hours but under conditions here humidity is below 80%, the time taken may be longer. While overcoating a mist coat should first be applied to avoid bubbling due to air entrapment.
Notes : 1. Use off the mixed paint within the stipulated pot life period. 2. Both components are also available in liquid form for ease of application. 3. The product cures by reaction with moisture and may be applied at high humidity levels provided the blasted surface is free from condensation and meets the requirement of Sa 2.5 Swedish Standard 4. Brush and spray equipment should be cleaned with Thinner 870 otherwise equipment is liable to be damaged 5. At lower relative humidity, drying and curing are likely to be extended. 6. Damaged areas can be touched up with Epilux 4 Zinc Rich Primer Health & Safety : Please refer to the separate Safety Data Sheet available with detailed information.
