NT Sheet (NT-3000) 
Environmentally friendly waterproofing method for construction without use of separate primers and heat appliances with high-point synthetic rubber composite sheet that combines advanced asphalt waterproof sheet materials with adhesive flexible rubber asphalt coating materials with high tensile strength, heat resistance, etc.
Characteristics
- Integrated technology that combines high-adhesive flexible rubber asphalt coating material with improved asphalt sheet (complex waterproofing method)
- Ensure stability of adhesion due to high-adhesive flexible type features
- Ensuring integration of joint between asphalt compounds
- Eco-friendly waterproofing method without separate primers and heat fixtures
- Expecting Air Reduction Effect due to Simplification of Work
- Ensure material environmental stability, such as VOCs and heavy metals
