What are the similarities between polyurethane and ordinary epoxy resin products? Both can enhance the compressive and tensile strength of the cement floor or the floor and drainage ditch against corrosion by strong acid and alkali chemical solvents. Below, Hitop Machinery will specifically talk about the respective characteristics of these two products!
1. Both have good tensile resistance, no cracking, no falling off and other properties;
2. Both have strong acid resistance. Corrosion properties of alkali salts and various oils;
3. Both have the properties of dustproof, waterproof, surface wear resistance, heavy pressure resistance, and impact resistance;
4. The former topcoat is suitable for outdoor use, while the latter is suitable for indoor use; while the biggest weakness or shortcoming of the latter is that it is afraid of strong ultraviolet radiation, which will cause yellowing under strong ultraviolet radiation, that is, fade, but it will not
Decomposition also affects the use; however, the former is much improved in terms of weather resistance compared with the latter, especially the yellowing time of the former is much longer than the latter, so the former is often used for outdoor construction requirements.
In the above introduction, are you aware of the reasons why polyurethane raw materials are often used for exterior walls? For more information on polyurethane, please continue to pay attention to Hitop Machinery.(https://www.chinapumach.com/)
