Comparative Analysis Metallizing || Rust Anode.
Zinc Metallizing
Durable; 50+ year service life; porous
10–12 mils Min. 5mils
Requires deep anchor profile; SSPC-SP10/NACE 2
Thermal spray; must apply sealer and topcoat same day
Slower than liquid coatings; time-consuming
Brittle; prone to cohesive failure if overheated
Difficult; requires full re-blast; pinholes must be tested
Best on flat surfaces; poor for crevices, pack rust, tight joints
Edges difficult to coat; require special attention
Heat resistant; chemical resistant; acid sensitive
Sensitive to heat; cohesive failure risk
Dull grey
High initial cost; lower life cycle cost
Requires high energy and equipment
Not recommended for incentive/ decentive contracts
Not suitable for flame-hardened steel; pinholes cause failure; not viable in tight areas
Rust-Anode® Primer
Rated C5-Very High; resists immersion, salts, and cyclic corrosion (ASTM D5894, 10,000h)
Comparable to metalizing and hot-dip galvanizing surface preparation.
Minimal prep; SSPC-SP2/SP3 acceptable SP10 the norm.
Brush, roller, airless, electrostatic; single-component
Fast drying; efficient field application
Flexible; fusion bonding with substrate; no cracking 15% flexibility with no cracking
Easy touch-up; does not flake; no abrasion needed
Excellent for complex geometries and hard-to-reach areas
Superior edge coverage and adhesion. Can apply coating on stripe coats 3 hours later.
Impact and chemical resistant; performs in saltwater and marine air.
Applies from -5°C to 37°C; cures in up to 99% RH
Duplexes with HRCSA self-priming topcoat for 75 year coating.
Up to 65% cheaper than hot-dip galvanizing; 60% lower maintenance cost [Specific examples.]
Low VOC (285g/L); less CO₂, transport, and steel production
Standard application equipment.
Quantity comparison of equipment requirements for containment would be awesome.
Homologated by MTQ and MTO; recognized by AGA for ASTM A780 touch-ups
Can be applied alone or in duplex systems; rejuvenates galvanized structures [Again, specifics.]
