TL;DR: CRC Zinc It is a high-purity cathodic protection compound designed for heavy-duty galvanic rust prevention across high-humidity Malaysian industrial corridors. This structural formulation provides long-term steel asset defense against severe salt spray and tropical atmospheric moisture, ensuring immediate application readiness for heavy infrastructure procurement networks.
Zinc Purity in Dried Film: 95% of the highest purity zinc.
Binder System: Special epoxy binder matrix.
ASTM Standard Compliance: ASTM B117 Salt Spray Corrosion resistance exceeding 1,000 hours.
Flash Point (Without Propellant): 41°C.
Thermal Resistance Operational Limits: Continuous exposure up to 400°C.
Volatile Organic Compound (VOC) Content: 54.7% by weight, equivalent to 580 g/Litre including propellant.
Propellant Type: Hydrocarbon.
Target Film Thickness Profiles: Wet film thickness (WFT) of 150 microns; Dry film thickness (DFT) of 75 microns.
Average Film Thickness (Standard Application): 50 microns.
Theoretical Material Coverage: 6 square meters per Litre at a 75-micron dry film thickness.
Water Solubility Index: Completely insoluble.
Drying Time Matrix (at 20°C): 20 minutes to touch, 8 hours to recoat, and 24 hours to achieve a complete hard cure. Full chemical cure requires 72 hours.
Sub-station and Power Grid Infrastructure: Applied directly onto electrical transmission towers, power generation equipment, and high-voltage transformers.
Heavy Structural Logistics & Fleet Components: Utilized on structural steel sections, guard rails, commercial trailers, roofs, storage tanks, and fencing assemblies.
Marine and Offshore Structural Assets: Engineered for offshore oil rigs, commercial ships, railroad equipment, coastal installations, and ship-borne systems subjected to continuous salt spray.
MRO Mechanical Joints: Ideal for securing and sealing welding seams, rivet holes, and performing localized touch-ups over pre-galvanized coatings.
Application Boundaries: This formulation must not be applied directly to active electrical components, battery terminals, or solenoids due to the high electrical conductivity of the aerosol canister and metallic film. Do not apply in unventilated zones or areas lacking adequate respiratory protection.
CRC Zinc It stops corrosion through cathodic action (a sacrificial electrochemical process where zinc corrodes in place of the underlying iron or steel). The dense metallic film utilizes an advanced epoxy binder to secure 95% pure zinc particles uniformly across the substrate. In tropical environments characterized by high ambient heat and moisture, this flexible continuous protective film blocks water ingress while remaining structurally stable under thermal spikes up to 400°C. The complete water insolubility prevents chemical leaching or osmotic blistering under severe condensation cycles.
Highly Suitable For: Maintenance, Repair, and Overhaul (MRO) engineering procurement divisions requiring immediate-use anti-corrosion applications; structural engineers managing exposed steel plants in coastal zones; and operations demanding verified ASTM B117 salt spray compliance exceeding 1,000 hours.
Not Suitable For: Application environments requiring top-coating with conventional enamels without a dedicated barrier coat; operations requiring low-VOC or solvent-free materials; and application zones exceeding 400°C continuous operational temperatures.
Surface Decontamination and Mechanical Abrading: Execute thorough surface preparation by performing abrasive blasting to AS 1627.9 Class 2 standard. Ensure millscale, active rust, and foreign particulates are substantially removed until clean, grey metal is visible.
Substrate Inspection: Verify the metal surface is completely firm, clean, and dry before attempting application.
Agitation Protocol: Shake the aerosol canister thoroughly before use to ensure the dense zinc particles are fully suspended within the epoxy binder. The product is correctly mixed when the output is smooth and dries to a flat, uniform mid-grey finish.
Coating Application: Apply a wet film layer of approximately 150 microns to achieve the targeted 75-micron dry film thickness profile.
Curing and Re-coating Interval: Wait a minimum of 20 minutes for the coating to become touch-dry. Allow at least 8 hours before applying subsequent coats, and permit 24 hours for a hard cure before moving components back into standard production zones. Full cure stabilization finishes at 72 hours.
Post-Application Cleanup: Clean application equipment, nozzles, and over-spray immediately using compatible paint thinners.
Direct Application over Loose Contaminants: Applying directly over loose millscale or rust causes immediate adhesion failure, trapping moisture beneath the film and inducing rapid sub-film corrosion.
Improper Agitation: Failing to shake the canister thoroughly leaves the heavy zinc particles settled at the bottom, resulting in a zinc-deficient epoxy spray that lacks sacrificial cathodic efficacy.
Incompatible Top-Coating: Applying conventional enamel topcoats directly over the zinc layer without an intermediate barrier coat like an Etch Primer will cause chemical incompatibility and coating degradation.
Electrical Arc Exposure: Operating the aerosol canister near live electrical panels or solenoids can result in flash fire or electrical shock due to the conductive nature of the metal packaging.
In accordance with the Department of Environment (DOE) Malaysia under the Environmental Quality (Scheduled Wastes) Regulations 2005, all used and unused aerosol canisters must be gathered, logged, and disposed of through a licensed scheduled waste facility. Do not puncture, incinerate, or crush the canisters. Storage temperatures must be strictly maintained below 50°C to prevent thermal expansion and explosive can bursting. Adequate mechanical ventilation or certified respiratory equipment must be utilized to prevent the continuous inhalation of solvent vapors and airborne zinc mist.
