Cold Insulation Aerogel Coating

Description

Cold insulation aerogel coating

1. Product Overview

Used on surfaces of equipment and pipelines transporting low-temperature media in industrial settings, this coating provides insulation and prevents condensation. Compared with traditional cold insulation materials, aerogel coating is easy to apply, highly effective, and cost-efficient.

4. Product Features

Traditional cold insulation of low-temperature pipelines/equipment often uses polyurethane foam, which has multiple seams, ages quickly, low fire resistance, and complex installation (especially for shaped components and large equipment). Over time, condensation and icing often occur.

This aerogel coating system addresses these issues, offering simple application, seamless coverage, and long-lasting energy efficiency.

6. Application Methods

Preparation:

Item	Spray	Trowel/Roll
Surface Requirement	Clean, debris-free, oil-free, dry, and level. Clean and de-grease if necessary.
Tools	Sprayer, roller, masking tape, mixer, protective mask, suit, harness, helmet, shoes, goggles, protective film	Trowel, scraper, roller, masking tape, mixer, protective mask, suit, harness, helmet, shoes, goggles, protective film
Recoat Interval	Wait until first coat dries, typically ≥24h
Conditions	Temperature 5–80°C. Extend recoat time if humidity >85%
Method	Stir with electric mixer ≥1 min before application
Tool Cleaning	Wash promptly with tap water

Procedure:

1. Open and stir: check for stratification, stir evenly (>1 min), avoid high-speed dispersion.
2. Apply coating by spraying 1–5 layers, thickness based on environment, area, quality requirements, and client needs.
3. Clean surface of rust, oil, dust; treat rusted areas with rust-conversion and anti-rust methods. Apply coating at ≥5°C.
4. For smooth surfaces or equipment transporting special fluids/gases, plan additional interface layers if necessary.
5. Apply aerogel coating to achieve required insulation effect or thickness. First layer ≤1mm, dry, then increase layers. From second layer, single layer ≤2mm. Final layer must be smooth. Natural drying 48h before use.
6. Coating Structure

The cold insulation aerogel coating is mainly applied as a middle layer. Existing coating processes are sufficient, requiring no special equipment. Structure:

• Topcoat:Scratch resistance and aesthetic finish
• Middle layer:Insulation, applied per calculated thickness
• Primer:Rust and corrosion protection for pipelines
