Polyurethane Waterproof Coating A Std 939 - China

Product Description

The polyurethane prepolymer has a high resin content with excellent ratio of NCO, which can form a highly dense and elastic waterproof membrane after being cured and shaped by the curing agent.

Our company’s several types of polyurethane prepolymer, with our corresponding curing agent, can reach different levels of waterproof membrane.

The mixture is easy to apply, and can be applied by roller application or spray application according to the requriement of the project.

Usage

After mixing the polyurethane prepolymer with its corresponding curing component in the recommended ratio and ensuring thorough stirring, apply it using roller coating or spray coating methods.

Packaging

20kg/pail, 200kg/drum Shelf life

12 months Storage and Transportation

Storage: Store the polyurethane prepolymer in a dry, cool, and well-ventilated environment, avoiding direct sunlight and exposure to extreme temperatures.

The storage temperature is typically between 15°C and 25°C.

Additionally, avoid contact with water, acids, bases, and other harmful substances.

Secure Stacking: Stack the buckets or drums securely to prevent them from falling or rolling.

Use appropriate securing devices like straps or brackets to ensure stability during transport.

Leak Prevention: Ensure that the buckets or drums are tightly sealed to prevent any leaks.

Leaks can lead to environmental pollution, safety hazards, and loss of product.

Secure Loading: When loading the buckets or drums onto the transport vehicle, ensure that they are properly secured and distributed evenly to avoid any imbalance or overloading.

Emergency Preparedness: Have an emergency response plan ready, including contact information for emergency services and procedures to follow in case of leaks, spills, or accidents.
