Hydroxypropyl Starch Ether (HPS) is a modified starch product that is used in the construction industry as a thickener, binder, and water-retention agent. HPS is made by treating corn starch with hydroxypropyl groups, which gives it unique properties that make it useful in various construction applications.
One of the main applications of HPS in construction is as a thickener. HPS has excellent thickening properties and can be used to increase the viscosity of aqueous suspensions, such as paint, adhesives, and mortars. This improved viscosity can help to improve the workability and spreadability of these products, making them easier to apply and use.
HPS is also used as a binder in construction. It can help to improve the cohesive strength of materials, such as mortars, adhesives, and grouts. This improved cohesive strength can help to improve the overall performance of these products, making them more durable and resistant to cracking, shrinkage, and other forms of degradation.
HPS is also used as a water-retention agent in construction. It can help to improve the water retention of mortars, adhesives, and grouts, helping to improve their workability and overall performance. This improved water retention can also help to reduce the risk of cracking and shrinkage, making these products more durable and reliable.
In conclusion, HPS is a versatile and useful ingredient in the construction industry. Its ability to improve the viscosity, cohesive strength, and water retention of various construction materials makes it an essential component in the development of high-quality and reliable construction products. Its ease of use and cost-effectiveness make it a popular choice in a wide range of applications, from small-scale residential projects to large-scale commercial construction.
