In a changing climate, whether it is outdoor camping, cargo transportation or temporary shelter, tarpaulins play an indispensable role. However, in the face of sudden rain, not all tarpaulins can provide equal protection. coated tarpaulin fabric, with their unique waterproof coating design, have become a powerful assistant to block rain penetration and protect the area below from rain.

The waterproof secret of coated tarpaulin fabric
The key to the effective waterproofness of coated tarpaulin fabric lies in the special waterproof coating applied to their surface. This coating is usually made of polymer materials such as polyurethane (PU) or polyvinyl chloride (PVC). Polyurethane (PU) coating is known for its good elasticity, wear resistance and environmental protection. It can provide excellent waterproof performance while keeping the tarpaulin light. Polyvinyl chloride (PVC) coating is known for its extremely high waterproofness and durability, and is suitable for occasions that need to be exposed to severe weather conditions for a long time.

These coating materials are evenly covered on the surface of the tarpaulin through a special process to form a dense waterproof barrier. When rain falls on a coated tarpaulin, the water drops slide down the smooth surface instead of penetrating into the tarpaulin. This "lotus effect" not only ensures that the area under the tarpaulin remains dry, but also reduces the weight of the tarpaulin due to water absorption, improving the convenience and safety of use.

Advantages of coated tarpaulin fabric
Excellent waterproof performance: coated tarpaulin fabric can resist the erosion of rain for a long time and keep the area below dry even in continuous rainfall.
Strong durability: Polyurethane and polyvinyl chloride coatings have good weather resistance and can resist damage from natural factors such as ultraviolet rays and weathering, extending the service life of the tarpaulin.
Easy to clean: The coating surface is smooth and not easy to be stained with dirt, making it easier and faster to clean.
Versatility: coated tarpaulin fabric are not only suitable for outdoor camping and cargo transportation, but also can be used in many fields such as construction site covering and agricultural shading.
Limitations of uncoated tarpaulin fabric
In contrast, uncoated tarpaulin fabric have obvious shortcomings in waterproof performance. Such tarpaulins are usually made of ordinary fabrics without additional waterproof coating protection, so rainwater can easily penetrate into the interior of the tarpaulin, causing the area below to become damp. Although its waterproof performance can be improved by using tools such as waterproof spray, this method has limited effect and short duration. Waterproof spray usually needs to form a thin waterproof film on the surface of the tarpaulin, but this film is easily worn or fallen off in daily use, thus losing its waterproof effect.
