Acid and Alkali Resistant Paint — ARMOUR SB
Single-component, self-priming acid & alkali resistant coating
Formerly known as: CRAC — Chemical Resistant Anti Corrosion Paint (As Patented)
ARMOUR SB is an acid and alkali resistant paint — a solvent-based, single-component self-priming coating engineered for fast application with a 15-minute touch dry time. It delivers strong acid, alkali, UV, and water resistance, ensuring long-lasting protection in demanding environments.
- Single component — no mixing required
- Self-priming on all metal & non-metal surfaces
- Touch dry in 15 minutes
- Superior acid, alkali, UV & water resistance
- Permeability is Nil

Application
ARMOUR SB can be applied by brush, roller, or airless spray. No thinning is required. Apply in ambient temperature between 10 °C and 40 °C with relative humidity below 85%. Do not apply on wet surfaces or when rain is expected within 4 hours.
Minimum 2 coats recommended for all industrial environments.
- 1
Surface Preparation
Clean the surface thoroughly — remove rust, oil, grease, dust, and loose particles. Ensure surface is dry and free from contamination.
- 2
Application Method
Apply by brush, roller, or airless spray. For best results on porous surfaces, apply a thin first coat and allow to flash off before applying the second coat.
- 3
First Coat
Apply ARMOUR SB uniformly at 40–60 microns DFT. Touch dry in 15 minutes.
- 4
Second Coat
Apply second coat after 1 hour at the same DFT. Ensure full coverage with no pinholes or holidays. Allow 1 hour for full chemical cure before exposing to aggressive media.
Frequently Asked Questions
