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:
आर्किटेक्चरल वॉटरप्रूफिंग: छतें, बेसमेंट, बाथरूम, रसोई, बालकनी आदि।
बुनियादी ढाँचा: सबवे, सुरंगें, पुल, पूल और दीवार के माध्यम से पाइप।
औद्योगिक अनुप्रयोग: रासायनिक संयंत्रों, सीवेज उपचार संयंत्रों और उच्च और निम्न तापमान वाली पाइपलाइनों के लिए संक्षारण प्रतिरोधी वॉटरप्रूफिंग।
5. किफायती और आसान रखरखाव
लागत बचत: उच्च ठोस सामग्री और उच्च कवरेज दर। 1.5 मिमी मोटी कोटिंग के लिए लगभग 1.5-2.1 किग्रा/㎡ की आवश्यकता होती है।
आसान स्थानीय मरम्मत: क्षतिग्रस्त क्षेत्रों की मरम्मत सीधे पेंटिंग द्वारा की जा सकती है, जिससे पूर्ण नवीनीकरण की आवश्यकता समाप्त हो जाती है। मजबूत पंचर प्रतिरोध: विशेष आणविक संरचना इसके उत्कृष्ट पंचर प्रतिरोध को निर्धारित करती है, जो इसे उन परिदृश्यों के लिए उपयुक्त बनाती है जहां तेज वस्तुएं संपर्क में आती हैं।
