Epoxy Primer · Paint & Coating Systems
PPG / Sigma SigmaCover Winter Grade Grade is a epoxy primer. It is normally installed or arranged in the specified hull, tank, deck or machinery surface. Its purpose is to protect the substrate against corrosion, fouling, chemicals, weather, slip or fire exposure. The equipment is based on coating layers whose performance depends on surface preparation, mixing, application and curing. The exact model designation distinguishes the installed configuration from neighboring variants in the same category; refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect coated surfaces for blistering, rusting, cracking, peeling, mechanical damage and edge breakdown. Identify and remove the cause of moisture, contamination or chemical attack before local repair. Prepare the substrate and apply compatible repair coats according to the approved coating specification. Maintain batch, mixing, curing and environmental records where required by the vessel coating plan. Pay particular attention to welds, edges, drains and high-abrasion zones. Refer to the manufacturer documentation for the exact figure for surface preparation, dry-film thickness, curing and overcoating requirements.
Keep compatible primer, intermediate and topcoat materials required by the vessel coating scheme together with approved thinners, repair materials and application consumables. Respect shelf life and storage conditions and do not substitute a different coating chemistry without compatibility checks.
