Item specifics
There are two most common processes for applying tarpaulins: knife-coating and coating. Let's discuss the characteristics and applications of knife-coated PVC tarpaulins, and which applications are best suited for waterproof PVC fabric.
Knife coating PVC tarpaulin Product Description
Knife coating PVC tarpaulin is a high-performance composite fabric renowned for its exceptional strength, waterproof properties, and long-lasting durability.
This Knife coating PVC tarpaulin advanced production process uses a precision doctor blade system to evenly apply liquid PVC to a polyester base fabric, creating a strong, uniform coating that bonds tightly to the textile fibers.
Compared to traditional Knife coating PVC tarpaulin, PVC knife coated tarpaulin offer a smoother surface, higher tensile strength, and longer service life, making them suitable for industrial, transportation, construction, and outdoor applications.
PVC knife coated tarpaulin Knife Coating Process Overview
Knife coating technology is a specialized process involving:
Base fabric—High-strength polyester yarn serves as the core structure.
Coating plate—Liquid PVC paste is evenly applied to both sides of the fabric using a knife.
Curing and heating—The coated fabric undergoes a high-temperature oven curing process.
Surface treatment—Optional varnish or UV coating enhances weather and chemical resistance.
Finished product—The final PVC tarpaulin is wound on a roll and can be further cut, welded, or printed.
This process ensures uniform coating thickness, strong adhesion, and excellent resistance to tearing or delamination.
Product Features
Excellent Strength and Durability
Tightly bonded PVC and polyester fiber layers create a durable fabric that resists tearing, abrasion, and stretching.
100% Waterproof and Weatherproof
The dense PVC coating completely seals the fabric, ensuring waterproofing even after prolonged exposure to sunlight.
UV and Heat Resistance
Special anti-UV additives prevent fading and material degradation in sunlight.
Smooth Surface, Easy to Clean
The scraped coating offers a smooth, stain-resistant, and easy-to-clean surface, making it ideal for outdoor use.
Customizable Specifications
Thicknesses range from 0.35 mm to 1.2 mm, weights from 180 g to 2000 g, and widths up to 3.2 meters.
Colors, printed logos, and flame retardant ratings are all customizable.
Long Service Life
Scraped tarpaulins are more durable than film-coated tarpaulins and offer superior performance in extreme environments.
