Production Description：
JHSW8601 is a high-performance pure polyurea waterproofing material specially designed for concrete protection and waterproofing applications. As a 100% solids, zero VOC, spray-applied aromatic pure polyurea coating, it provides a seamless, flexible, and highly durable protective layer with excellent elongation, impact resistance, and abrasion resistance.
Its outstanding flexibility allows the coating to bridge cracks and accommodate substrate movement, making it an ideal solution for concrete structures and other surfaces requiring long-term waterproof protection. With ultra-fast curing characteristics and excellent environmental adaptability, JHSW8601 can maintain stable performance under various temperature and humidity conditions.
The system consists of A component, a quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, amine extenders and other additives.It can be applied on concrete, metal, wood, foam and other substrates, providing reliable protection against water penetration, corrosion, and mechanical damage.
Advantages：
● 100% Solids & Zero VOC
Environmentally friendly coating system with no solvents, no odor, and no toxic vapor emissions.
● Excellent Waterproof Performance
