Product Description

NMA is made of high quality petroleum asphalt, functional polymer modifier and special additives through scientific optimization. NMA has outstanding creep properties, and the resulting self-healing, prevent leakage, channeling water proof, fatigue resistance, ageing resistance, no stress such outstanding application features.
Generally, NMA and modified bitumen waterproof membrane together form composite waterproof layer.

Where to use
NMA is suitable for undulating area, large stress area, and the area which may happen shape change or always change, particularly suitable for the project which is not allowed flame construction, mechanical application project and cold application project.
NMA is suitable for concrete roofing, steel roofing, underground, pond and tunnels waterproof constructions.

Advantages
Excellent adaptability for the structural deformation
NMA can adapted to structural deformation, when the basement cracking and waterproof layer stretching, NMA can absorb stress, close micro-cracks of the basement level, to ensure the entire waterproof system maintain integrity long-term.
Excellent self-healing ability
When NMA waterproof layer is punctured by external force, the broken point would not extend, the bottom of waterproof layer would not happen channeling water, and the creep properties of NMA enables self-healing after the destruction of the material, which improve waterproof layer reliability, reduce the cost of repair and maintenance.
Excellent aging resistance, low temperature flexibility, chemical corrosion resistance.
Excellent adhesion performance
NMA can bond with different basement surface, excellent adhesion performance.
Easy application
Feeding in and pumping out continuously, NMA can be applied to the specified thickness once, construction speed is around 115m2/hour.
Safety and environmental protection
NMA solid content is over 99%, non-toxic, solvent-free, no open flame when application, safety and environmental friendly.
