Don’t Pay the Price of (Other Coating’s) Failure…
Labor cost to remove layers by sanding/scraping or patch primer.
Labor cost to repair, prepare and clean surface.
Labor coast to re-prime and re-coat surface.
Materials cost to replace coating that had to be removed.
Cost of downtime while primer cures, and while coating cures.
Extensive coating failure requires total replacement of coated item.

Coval Difference 101
Other coatings suffer from fractures of top coat occur when substrate and coating expand and contract at different rates. As coatings age, they become harder and less flexible; across the coating spectrum, thin films tend to crack less than thick films. Fractures expose substrates to weathering, moisture, organism growth, dirt, etc. Fracture types include peeling, flaking and delamination. Coval Coatings covalent bond is part of the substrate – it expands/contracts as one - and can’t fracture..
Steel & coating layers expand and contract at different rates
Many temperature
cycles
Mechanism of a Fracture
Profile too small gives poor key for adhesion.
Profile too large means peaks may protrude through the paint film as paint flows away from peaks.
Steel Profile Weak coverage over high peaks of blast profile
Low film thickness of paint over steel with large blast profile
Coating
Blast Profile Effect
Because Coval Coatings are nano-sized, they fill in each gap. Superior adhesion (covalent bond) and micro-thin coating requirements mean Coval Coatings completely coat over peaks, troughs, pits and gaps.
Coval Products Prevent 10 Common Application Issues
CissingCaused by contamination of surface, such that coating cannot wet surface fully.
Welding IssuesWeld flux residues absorbs water and then dissolves in it, causing corrosion to break through coating. Coating applied over weld spatter breaks down early due to coating shrinkage stress.
LappingBrush strokes and spray pass stay visible after drying.
Pin holingCircular pits void of coating caused by bubble breakage at a stage in cure when coating cannot flow and repair itself.
WrinklingHappens when surface of coating dries, but under portion of coating remains soft for a longer time.
Corrosion & Rash RustingCaused by blast profile effects, poor surface preparation and/or poor product choice
Blistering & BubblingLiquid/gas pressure on coating greater than adhesion strength causes localized detachment. Often occurs painting over porous surfaces.
ChalkingUV degradation of coating resin at surface causes breakdown and release of pigment particles.
CheckingCaused by contraction of top coat during curing.
Edge & Corner FailureBlast profile effects on metal burrs and tendency for surface tension created during curing to cause coating to shrink and pull away from edges.
Micro-thin Coval Coatings dry quickly for smooth, even coverage.
Coval Coatings create a covalent bond to make a new surface (substrate + coatingnot coating over substrate) for extremely strong adhesion.
Coval Coatings fill in nano-sized pits and burrs to totally protect surface. Viewed under a microscope, other coatings show “basketball-sized” pits & erratic coverage.
Coval Coatings anti-fracture structure expand/contract along with the surface they protect so they never crack, peel or flake.
Coval Prep Products completely clean & prepare surfaces, even over welding.
Coval Coatings are UV resistant to prevent oxidation or breakdown.
