RCS-WSM Waterproofing Sealing Mastic

Key Features

Self-Fusing, High Adhesion

The RCS-WSM tape self-fuses without the need for solvents or additional adhesives, creating a seamless, waterproof seal. It provides high adhesion to a wide variety of materials, including metals and cable insulations, ensuring a secure, long-lasting bond that performs reliably over time.

Weather Resistance

Engineered to withstand extreme weather conditions, the tape offers excellent resistance to UV rays, rain, and temperature fluctuations, making it suitable for both indoor and outdoor applications.

High Flexibility and Elongation

The mastic is highly flexible, capable of stretching and conforming to irregular shapes and surfaces, ensuring a tight, reliable seal on complex joints and terminations. Its high elongation at break ensures that it can handle physical stresses without cracking or failing.

Insulating and Anti-Aging Properties

Designed for electrical applications, this mastic provides effective electrical insulation to protect against short circuits and electrical faults. It also offers anti-aging properties, maintaining its performance without degrading over time, even under harsh conditions.

Non-Toxic and Safe to Use

The mastic is non-toxic, making it safe for both installation and long-term use, even in sensitive environments such as homes or commercial buildings.

Self-Amalgamating and Solvent-Free

The self-amalgamating nature of the tape allows it to fuse to itself without the use of harmful solvents, making installation clean and easy, without any chemical residue.

Wide Operating Temperature Range

The tape performs effectively in temperatures ranging from -40℃ to 90℃, ensuring reliable sealing and protection in both cold and hot environments.

Applications

Cable Terminations and Joints (Up to 36 kV)

The mastic is primarily used for sealing and insulating cable terminations and joints, providing a waterproof seal that prevents moisture ingress and protects the integrity of electrical systems.

Bonding and Sealing Electrical Equipment Connectors

Ideal for bonding and sealing electrical equipment connectors, the mastic ensures that electrical connections remain secure and protected from moisture and corrosion, preventing faults and improving system reliability.

Sealing Heat Shrink Mould Parts

The mastic is also effective for sealing heat shrink mould parts, providing a reliable seal that prevents moisture ingress and helps maintain the integrity of the connection.

General Purpose Waterproof Sealing

In addition to electrical applications, the tape is suitable for general-purpose waterproof sealing in various industrial and commercial settings, offering protection in environments exposed to the elements or harsh conditions.
