DY-14Acid & Alkali Resistant Coating
A dense protective coating for surfaces exposed to acid, alkali, oil and corrosive process environments.
Product overview
Chemical-resistance protection for prepared industrial surfaces where exposure must be confirmed by medium and contact pattern.
DY-14 is a two-component ambient-cure coating described in the source package as a modified epoxy resin system with ceramic, silicon-carbide, alumina and flake acid-resistant fillers.
Industrial problems
- Acid or alkali exposure
- Liquid splash and acid mist
- Oil exposure
- Permeation and underfilm corrosion
Typical equipment and locations
- Chemical process areas
- Containment and drainage zones
- Equipment shells and steelwork
- Concrete and masonry surfaces requiring chemical review

Preparation, mixing and application
01
Surface preparation
- Abrasive blast steel to Sa 2.5 with a 30–60 μm surface profile.
- For local repair, remove oil, loose rust and scale, then power-tool clean to St 3.
- Apply promptly after cleaning to avoid flash rust and contamination.
02
Mixing and application
- Mix base and hardener 3:1 by weight for 3–5 minutes; the package label governs.
- Source reference pot life: 5–8 hours.
- Apply by brush, roller, air spray or airless spray.
- Maintain substrate at least 3°C above the dew point.
