When epoxy coatings failure occurs in the facility, repair, and maintenance is inevitable. Facility managers tolerate the costs incurred by repair activities, because failing to rectify the epoxy coatings failure can lead to more severe negative effects.
Understanding the causes of epoxy coatings failure leads to better choices of paints and more careful surface preparation and application. Elemental factors and particulate matters are known to cause epoxy coatings failure more often, but there are other notable causes of epoxy coatings failure that, when known and addressed carefully, can help avoid costly disruptions in the facility.
Here are some of the sources of epoxy coatings failures in facilities:
Solvents can cause ridges in coated surfaces that dried too quickly. When thick epoxy coatings dry fast, they tend to trap solvents underneath and lead to failure in the top coat. The solution is to use solvent-free epoxy coatings.
Phenolic epoxy coatings are inherently brittle, causing cracks in the surface as it moves expands or contract. When cracks appear, corrosion and moisture damage eventually set in. Epoxy coatings products with good elongation properties can solve this problem.
Water or chemicals are freely absorbed by porous epoxy coatings. Applying non-porous epoxy coatings will address this threat and lessen the risk of coatings failure.
