Understanding Polyurethane

Polyurethane is a synthetic polymer that can be formulated into various materials, including coatings, foams, and fabrics. It is prized for its versatility, durability, and water-resistant properties, making it a popular choice for a wide range of applications, from furniture upholstery to automotive parts.

Advantages of Polyurethane for Raincoats

Polyurethane offers several advantages when used in raincoat construction, making it a viable option for wet weather apparel.

Water Resistance

One of the primary reasons polyurethane is used in raincoats is its excellent water-resistant properties. Polyurethane coatings applied to fabric create a barrier that repels water, keeping the wearer dry and comfortable even in heavy rain.


Polyurethane-coated fabrics retain their flexibility and suppleness even when exposed to moisture, unlike some other water-resistant coatings that may stiffen or crack over time. This flexibility allows for ease of movement and comfort when wearing a polyurethane raincoat.


While polyurethane creates a barrier against water, it also allows moisture vapor to escape from the inside of the raincoat, preventing the wearer from feeling clammy or sweaty. This breathability is essential for maintaining comfort during prolonged wear, especially in humid conditions.

Considerations for Polyurethane Raincoats

Despite its advantages, there are some considerations to keep in mind when choosing polyurethane for raincoat construction.


While polyurethane-coated fabrics are generally durable, the longevity of a polyurethane raincoat can vary depending on factors such as the quality of the coating and the frequency of use. Over time, exposure to UV radiation, abrasion, and other environmental factors may cause the polyurethane coating to degrade or delaminate, compromising its water-resistant properties.

Care and Maintenance

Proper care and maintenance are essential for maximizing the lifespan of a polyurethane raincoat. Avoiding harsh chemicals, excessive heat, and abrasive cleaning methods can help preserve the integrity of the polyurethane coating and ensure continued water resistance.


In conclusion, polyurethane offers several advantages for raincoat construction, including water resistance, flexibility, and breathability. These properties make it a suitable choice for wet weather apparel, providing protection and comfort to the wearer. However, it's important to consider factors such as durability and maintenance when choosing a polyurethane raincoat to ensure long-lasting performance.
