Why is polyester resin alone sometimes not enough?
Polyester resins are the basis of many laminates, tanks, and technical components. They are cheap, easy to apply, and available at every wholesaler. However, in harsh conditions – high humidity, aggressive chemicals, higher temperatures – orthophthalate and even isophthalate polyesters quickly give out. Osmosis and cracks appear, and the surface loses its properties.
What makes Atlac 580 stand out?
- Chemical resistance to acids, alkalis, and aggressive environments,
- Thermal resistance – withstands temperatures at which polyester or epoxy degrades,
- High mechanical strength and flexibility,
- Durability – installations made with Atlac 580 operate for even 15+ years where polyester lasts 3–5.
Where does it perform best?
- Sewage treatment plants and water supply systems – tanks, pipelines, corrosion-resistant components.
- Food industry – floors and laminates resistant to detergents, organic acids, and brines.
- Agriculture and agro-industry – silos, tanks, installations exposed to fertilizers and silage.
- Yacht industry and shipbuilding – hulls, submerged components, protection against osmosis.
- Industrial construction – coatings and floors in halls, plants, and workshops.
When is it worth choosing Atlac 580?
If your project must withstand chemicals or high humidity, the investor expects a long service life without expensive repairs, and polyester cannot cope (and epoxy degrades too quickly), then Atlac 580 is the best choice.
Why is the cheapest solution not always worth it?
The price of polyester may be tempting, but it is worth looking at the total cost of ownership.
- Polyester = lower purchase price, but frequent repairs and rapid degradation.
- Atlac 580 = higher upfront price, but up to 3× longer durability → real savings over time.
Summary
“When polyester is not enough” – that is when you reach for Atlac 580. It is a solution for those who think long-term: industrial investors, contractors, and manufacturers who want to deliver solutions resistant to time, chemicals, and harsh environmental conditions.
