OVERVIEW: Since re-coating Chemcote’s team has ensured the Extension Leveller is now in excellent condition and maintenance costs have also been drastically reduced.
INDUSTRY
ENVIRONMENT
Recycled cooling water
SUBSTRATE
Steel
CHALLENGE
Asset owners of the Extension Leveller Cassette engaged us to inspect and nominate a complete coating solution where standard paint systems failed to prevent surface deterioration resulting in
large refurbishment costs
SOLUTION
RL 500PF is a surface / wet tolerant zinc rich
epoxy, required to a uniform thickness for
smooth functioning
SCOPE
Grind sharp edges and weld porosity
Abrasive blast to AS 1627.4 Class 3, 75µm profile
Application of RL 500PF with nominate thickness 300 microns
Application of 1 coat of RC 500GTC to a final DFT of 400µm
PRODUCTS
OUTCOME
Since re-coating was carried out by Chemcote, the extension leveller has been found to be in excellent condition and maintenance costs have been dramatically reduced

OVERVIEW: Chemcote’s specialist team mobilised to site to deliver a multiple layer protective coating system that would return the asset to working condition within 24 hours. Abrasion resistant coatings were applied to the pugmill and paddles over a 12 hour period during plant shutdown, with 12 hours allocated for curing.
INDUSTRY
ENVIRONMENT
50-70°C 10-40μm abrasive particles from the dust catcher are disposed of in the pugmill and combined with water to suppress the dust creating an abrasive sludge
SUBSTRATE
Steel Substrate
CHALLENGE
Deliver an operational multi coat abrasion resistant coating system within 24 hours
SOLUTION
Thorough surface preparation prior to the application of multiple layers of abrasion resistant coatings. Spot abrasive blasting to minimise disruption to surrounding trades.
SCOPE
Pugmill Internals
Spot abrasive blast localised areas.
Apply of 1 coat of fast curing Chem-tect™ RB 364C to areas where required
Use chopped strands and where deep pitting existed to provide a smooth even profile
Apply 2 coats of Chem-tect™ RB 364CS to 1,000μm
Conduct QA, DFT and high voltage spark test to ensure continuity at required voltage
Paddles
Abrasive blast to AS 1627.4, Class 2.5 with a minimum 75μm profile.
Apply 1 coat of Epo-chem™ RW 500 to a nominal thickness of 500μm to ensure no transparent areas
Complete casting application 1 coat of InD-cote™ to 6000 micron DFT to the load and back faces
PRODUCTS
Paddles coated using Epo-chem™ RW 500 and InD-cote™
Pugmill Internals Chem-tect™ RB 364CS
OUTCOME
Chemcote’s solution has extended the life of this asset by 12-24 months, and delivered a 30% improvement in functioning. Continuous high performance is guaranteed until our review at the next planned outage.
