About This Service

What Is Polyurethane Food Grade?
And How Does It Work?

Polyurethane Food Grade is a specialist polyurethane coating for the food and beverage industry — delivering a highly flexible protective layer that resists impact, thermal change, and vibration, with excellent UV resistance for outdoor tanks and demanding food environments.

Made from materials certified safe for food and potable water contact, Polyurethane Food Grade is highly flexible, UV stable, and impact resistant — ideal for outdoor tanks, dairy plants, breweries, and food factories.

Key Features

Capabilities of Polyurethane Food Grade

A food-grade polyurethane coating that is highly flexible, UV stable, impact and temperature resistant — protecting tanks of every type in the food industry against corrosion and contamination.

Food Safety Certified
Uses polyurethane certified safe for food and potable water contact — non-toxic, environmentally friendly, and will not alter the smell or taste of the product.
High Flexibility & Impact Resistance
The polyurethane coating layer is highly flexible, accommodating tank expansion and contraction from temperature changes while withstanding impact and vibration in real operating conditions.
UV Resistant — Ideal for Outdoor Use
Excellent UV resistance prevents degradation from sunlight and weathering — suitable for tanks and equipment installed outdoors or exposed to direct sunlight.
Wide Temperature Range Performance
Retains excellent mechanical properties across a wide temperature range — suited for both high-heat and extreme-cold environments such as cold rooms, hot mixing tanks, and plants with frequent thermal cycling.
Corrosion & Leakage Protection
The polyurethane coating shields tanks from corrosion, leakage, and microbial build-up — extending service life and reducing long-term maintenance costs.
Specialist Installation Team
A team of engineers and technicians trained specifically in food-industry tank coating — guaranteeing installation quality and product safety at every stage.
Work Process

The Polyurethane Food Grade Process

A systematic process carried out by specialist engineers — from tank inspection and surface preparation through food-grade polyurethane application, quality testing, and warranted handover.

1
Tank Inspection & Assessment
Inspect tank condition, measure moisture, assess damage, and plan surface preparation — selecting the appropriate PU Food Grade system for the tank type and operating conditions.
2
Cleaning & Surface Preparation
Thoroughly clean the tank to remove rust, oil, and contaminants, then abrade by sandblasting or grinding to the specified roughness profile for maximum adhesion.
3
Polyurethane Food Grade Application
Apply a food-grade primer followed by the specified number of polyurethane coats — controlling thickness and uniformity throughout, with full cure time between each layer.
4
Testing & Handover
Test coating integrity and adhesion, issue a quality report and food safety certification, then hand over the completed work with a written warranty.
