Vinyl ester flooring is a fiberglass-reinforced resin floor system applied directly onto prepared concrete, and it is the specification normally chosen where a floor has to live with acid, alkali, brine or permanent immersion rather than occasional spills. ACF-VE-3F5C is declared against 75% sulfuric acid and 40% hydrochloric acid for seven-day immersion, with a quoted service life of 5\u201310+ years in the duty it was specified for. Choose vinyl ester over epoxy when the medium is concentrated acid, solvent or permanent immersion; stay with epoxy when the acid is dilute and the budget is the constraint. The ACF-VE-3F5C system builds three layers of fiberglass cloth into vinyl ester resin, adds a mortar and putty body, and seals everything under a roll-on vinyl ester topcoat at a finished thickness of 1\u20135 mm. This page covers what the resin actually is, which media the system resists and at what concentration, how the layers are built, how the floor is installed over an existing slab, and how to specify the right lay-up for your duty.<\/p>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

What is vinyl ester flooring and why is it used instead of epoxy?<\/h2>\r\n\r\n\r\n\r\n

Vinyl ester resin is an epoxy backbone that has been reacted with methacrylic acid so the molecule ends carry unsaturated groups that cross-link with styrene. That structure keeps the mechanical toughness of epoxy while reducing the number of ester linkages that acid and water attack, which is why vinyl ester flooring holds up in immersion service where standard epoxy coatings soften, blister or chalk.<\/p>\r\n\r\n\r\n\r\n

The practical difference on a project is not a laboratory number but a failure mode. Epoxy fails by losing bond at the concrete interface once moisture and acid reach the substrate; a vinyl ester laminate fails, if it fails at all, at the surface, and stays repairable. For a floor that will be washed down daily with acid or sit under brine, that difference decides whether the slab is protected for five years or replaced.<\/p>\r\n\r\n\r\n\r\n

Term note.<\/strong> Buyers searching for epoxy vinyl ester flooring are looking for this same family: the vinyl ester systems in this catalog are supplied as vinyl ester grades and, depending on the component, epoxy-vinyl ester hybrid grades. The shorter term vinyl ester is used throughout this page.<\/p>\r\n\r\n\r\n\r\n

What “three cloth five oil” actually means<\/h3>\r\n\r\n\r\n\r\n

The Chinese trade term for this build translates literally as three cloth, five oil. The oil is not oil: \u6cb9 is the historical word for a resin coat, from the period when binders were tung-oil based, and in a modern specification it means one application of resin. Three cloth five oil is three layers of glass cloth and five resin applications \u2014 a laminate build, not a coating with a thick topcoat.<\/p>\r\n\r\n\r\n\r\n

The distinction matters when quotations are compared. A supplier offering three cloth three coat is describing a thinner build behind a similar headline; the coat count is what fills the weave, seals the pinholes and builds the barrier. On a floor that meets acid daily, the gap between three and five resin applications is the gap between reaching the quoted service life and missing it.<\/p>\r\n\r\n\r\n\r\n

Which chemicals does ACF-VE-3F5C resist, and at what concentration?<\/h2>\r\n\r\n\r\n\r\n

The system is quoted against seven aggressive media, each tested by 7-day immersion with no change to the cured film. Concentration matters more than the chemical name, so the figures below are the ones to check against your process rather than a general claim of acid resistance.<\/p>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

Two boundaries are worth stating plainly. A 7-day immersion result is a screening test in the format of ISO 2812 and ASTM D543, not a service-life guarantee for a hot, concentrated or solvent-loaded stream. Where a process runs above roughly 40 \u00b0C, carries solvents, or alternates between acid and caustic, the lay-up and the topcoat grade have to be reviewed before the floor is priced \u2014 that review is part of the quotation, not an afterthought.<\/p>\r\n\r\n\r\n\r\n

Where the medium list runs past what one resin can carry, compare the options in corrosion resistant flooring by chemical duty before the system is fixed.<\/p>\r\n\r\n\r\n\r\n

How is the 3-cloth 5-coat vinyl ester flooring built up?<\/h2>\r\n\r\n\r\n\r\n

Each layer has one job, and the sequence is what turns a coating into a monolithic lining: the primer anchors to the concrete, the laminate carries load and bridges cracks, the mortar and putty build thickness and smooth the surface, and the topcoat becomes the chemical barrier.<\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. Concrete substrate<\/strong> \u2014 mechanically ground, dust-free, sound, with voids and cracks opened and filled before priming.<\/li>\r\n
  2. Vinyl ester penetrating primer<\/strong> \u2014 low-viscosity resin that soaks into the cement matrix and anchors the whole system; bond strength at this interface governs the life of the floor.<\/li>\r\n
  3. Glass fiber cloth \u00d7 3, bonded in vinyl ester resin<\/strong> \u2014 the structural layer. Three layers are laid wet-on-wet or wet-on-cured according to the lay-up, with each cloth fully wetted out and rolled free of air.<\/li>\r\n
  4. Mortar body<\/strong> \u2014 resin and graded aggregate that adds thickness, compressive capacity and impact resistance.<\/li>\r\n
  5. Putty<\/strong> \u2014 closes the weave and pinholes so the topcoat is applied to a continuous surface.<\/li>\r\n
  6. Vinyl ester roll-on topcoat<\/strong> \u2014 the chemical barrier, pigmented and uniform, applied in two passes to a sealed, dust-free finish.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

    Because every layer is chemically bonded rather than laid as separate sheets, there are no joints or seams. That is the reason the system is used on containment areas and tank floors, where a single failed joint would defeat the whole lining.<\/p>\r\n\r\n\r\n\r\n

    For a floor slab these numbers mean the system carries foot traffic, pallet trucks, drum handling and wash-down equipment without the surface breaking down. They do not make it a structural wearing course for steel-wheeled forklifts or drop-forging areas; where that duty exists, the high-build mortar system is the correct specification instead.<\/p>\r\n\r\n\r\n\r\n

    Where is vinyl ester flooring specified?<\/h2>\r\n\r\n\r\n\r\n

    The system is used wherever concrete meets aggressive liquid and the floor cannot be allowed to leak:<\/p>\r\n\r\n\r\n\r\n
