Acrylic Elastomeric Coating In Patna

Acrylic elastomeric coating is a high-performance, flexible, and durable protective coating widely used in construction and industrial applications—especially for roofing, walls, and other exterior surfaces. Here's a detailed breakdown:

🔍 What is Acrylic Elastomeric Coating?

Acrylic elastomeric coating is a water-based or solvent-based coating made from 100% acrylic polymers. It forms a rubber-like, seamless membrane that stretches and recovers as the surface expands or contracts due to temperature changes.

📌 Key Features

Feature Description

Elasticity Can stretch (up to 300-600%) without cracking—ideal for substrates that expand/contract.

UV Resistance High resistance to ultraviolet radiation, preventing degradation from sun exposure.

Waterproofing Excellent water resistance—used for waterproofing roofs and walls.

Breathability Allows moisture vapor to escape, reducing blistering or peeling.

Reflectivity High solar reflectance (especially white coatings), reduces building cooling costs.

Durability Long lifespan (10-20 years with proper application and maintenance).

Crack Bridging Fills and bridges hairline cracks, preventing water ingress.

🏗️ Common Applications

Roof Coating (flat or low-slope roofs – concrete, metal, bitumen, etc.)

Exterior Walls (stucco, concrete, masonry)

Metal Buildings

Parapet Walls

Sealing and Weatherproofing joints, cracks, and expansion areas

🧪 Typical Composition

Acrylic resin (binder)

Pigments (for reflectivity and color)

Fillers (to add bulk and texture)

Additives (for UV resistance, mildew resistance, etc.)

Water or solvents (carrier medium)

🧰 Application Process

Surface Preparation:

Clean thoroughly (pressure wash if needed)

Repair major cracks and defects

Allow surface to dry

Priming (optional but recommended on porous or chalky surfaces)

Application:

Usually by spray, roller, or brush

2–3 coats are common for best results

Allow adequate drying time between coats (varies by brand/environment)

Drying Time:

Touch dry: 1–2 hours

Full cure: 7–14 days

📦 Typical Technical Specs (Approximate)

Property Value

Elongation 300–600%

Tensile Strength 200–400 psi

Permeability Breathable, yet waterproof

pH Range 8–9 (alkaline)

Color Usually white, but available in other colors

✅ Advantages

Energy-efficient (cool roof systems)

Environmentally friendly (low VOC for water-based types)

Easy to apply and maintain

Compatible with many substrates

⚠️ Limitations

Should not be applied in freezing or rainy conditions

Requires clean, dry, sound substrate

Not suitable for ponding water (unless specially formulated)

May require recoating every 10–15 years
