Rubber waterproof coatings are one- or two-component liquid waterproofing materials based on synthetic rubber latex (such as styrene-butadiene rubber and chloroprene rubber) or polymer elastomers (such as polyurethane and acrylates) through a special modification process. They cure at room temperature (completely curing in 24-48 hours at 25°C), and some products can be applied at low temperatures (5°C) or in humid environments. They offer tensile strengths of 2-6 MPa and elongations at break of 300%-1000%, and can adapt to minor deformations of the substrate.
1. Excellent Waterproofing Performance
High Elasticity and Extensibility: The coating boasts an elongation at break of 300%-1000%, resisting leakage caused by expansion and contraction of the base layer and cracking.
Seamless Connection: Spraying or brushing creates a continuous waterproof layer, eliminating water leakage through the membrane's seams and joints.
Self-Healing: Some products (such as high-elastic rubber waterproof coatings) have a self-healing rate of up to 90%, automatically healing after damage, reducing subsequent repairs.
2. Excellent Physical Properties
Weatherproof: Resistant to UV rays and alternating heat and cold, with a service life of 15-30 years (e.g., Fordis brand water-based rubber waterproof coatings offer a service life of up to 30 years).
Impact Resistance: The coating remains crack-free under a 50kg·cm impact force, making it suitable for heavy loads.
Chemical Resistance: Withstands immersion in 10% sulfuric acid and 5% sodium hydroxide solutions for 60 days without any changes, making it suitable for the chemical industry.
3. Environmental Protection and Construction Advantages
Water-based: Non-toxic, odorless, and pollution-free, meeting national environmental standards (e.g., extremely low VOC emissions). Cold application is safe: Cures at room temperature, requires no open flame, has low odor, and is harmless to workers.
Short construction period and high efficiency: Cures quickly, saving time and costs.
4. Wide applicability
Strong substrate compatibility: Bonds to a variety of materials, including concrete, cementitious surfaces, metal, glass, and ceramics.
Complex surface application: Applicable to damp (moisture content <10%) and slightly uneven surfaces, overcoming the limitations of traditional materials.
Versatile applications:
Kalis air seni bina: bumbung, ruang bawah tanah, bilik mandi, dapur, balkoni, dll.
Infrastruktur: Subways, Tunnels, Jambatan, Kolam, dan Paip Melalui Dinding.
Aplikasi Perindustrian: Kalis air tahan karat untuk loji kimia, loji rawatan kumbahan, dan saluran paip suhu tinggi dan rendah.
5. Penyelenggaraan Ekonomi dan Mudah
Penjimatan Kos: Kandungan pepejal yang tinggi dan kadar liputan yang tinggi. Salutan tebal 1.5mm memerlukan kira-kira 1.5-2.1kg/㎡.
Pembaikan tempatan yang mudah: Kawasan yang rosak boleh diperbaiki secara langsung dengan melukis, menghapuskan keperluan untuk pengubahsuaian lengkap. Rintangan tusukan yang kuat: Struktur molekul khas menentukan rintangan tusukan yang sangat baik, menjadikannya sesuai untuk senario di mana objek tajam bersentuhan.
