Lockwell have a range of Polyurea’s ideal for heavy-duty water-proofing and more.
Like bund liners, abrasion resistant coatings, containment, conveyor belt repair, waste water treatment liners, pipes, tank liners, tailings pond liners, and a host of other industrial applications – nearly anywhere to protect the vital assets and infrastructure that keep your industry in business.
One of the biggest benefits to the Lockwell range is not just the latest formulations providing the best physical properties and excellent spray-ability, but all the polyurea variants, and the UP100 hybrid use the same ISO side. Given the ISO (Part A) has a shelf life of 12+ months, but the Resin (B-side) can last for 5 years or more, this means less wastage for applicators.
Our Polyurea coatings boast fast curing times, even at temperatures well below 0˚C, as well as insensitivity to humidity. With exceptional physical properties such as high hardness, flexibility, tear strength, tensile strength, chemical and water resistance, there’s sure to be a formulation to suit your assets.
We have a range of standard specifications available on request. When specifying Polyurea, there are key elements to consider. Many uneducated sales people and applicators will try and convince you that any polyurea is suitable as they are all the same. However, the ultimate performance is highly influenced by the following parameters;
- Tensile strength – High tensile strength improved puncture and tear resistance, and the higher the tensile capacity, the more resistance to particle abrasion and impacts.
- Elongation – High elongation is generally better because it allows for higher impact abrasion and resilience against thermal movement. It also helps with particle abrasion resistance when the tensile strength is still high.
- Purity – Generally, the more pure, the better the UV and chemical resistance. Be careful of cheap products because some people claim purity even though they have 10, 20 or even 40% urethane. Look for the PDA pure polyurea approval.
- Hardness – This isn’t hugely important for Polyurea in most situations. Abrasion resistance is better determined by the tensile and elongation balance for particle abrasion, but resistance against scraping abrasion may be improved by higher hardness.
- Taber Abrasion – This measure has found to not correlate well with any realistic requirement for abrasion resistance of polyurea. We don’t normally pay much attention to these values but provide them for reference.
