Description
SOPRASPHALTE M is a SEBS-based modified bitumen used to adhere SBS-modified bitumen membranes in roofing applications.
UNITS PER SKID: 40
Material Use:
SOPRASPHALTE M is a SEBS (styrene-ethylene-butylene-styrene) modified bitumen adhesive specifically designed for use in roofing applications. It is primarily used to adhere SBS (styrene-butadiene-styrene) modified bitumen membranes to roof substrates, forming a durable and flexible bond that accommodates building movement and environmental stress.
System Components:
SOPRASPHALTE M is used as part of a hot-applied roofing system in conjunction with SBS-modified bitumen membranes. It acts as the adhesive layer in the system. While the TDS does not specify a primer, proper surface preparation and heating of the product are critical to ensure optimal adhesion. The system typically includes:
- SOPRASPHALTE M (adhesive)
- SBS-modified bitumen membrane (base and/or cap sheet)
Applications:
This product is intended for use in commercial and industrial roofing systems where SBS-modified bitumen membranes are installed. It is suitable for both flat and sloped roofs, as it is not limited by slope index. SOPRASPHALTE M is ideal for new construction, re-roofing, and repair applications where a hot-applied adhesive is preferred.
Application Details:
SOPRASPHALTE M must be applied using a mop, ensuring a uniform surface coating at a rate of 1.0 to 1.5 kg/m² (20 to 25 lb/100 ft²). The membrane should be unrolled directly into the hot bitumen, which must be at a temperature of 220 to 230 °C (425 to 450 °F) at the point of contact. Pressure should be applied to the membrane roll to create a wave of hot bitumen in front of it, ensuring full adhesion. Continuous agitation of the product in the melting kettle is required during heating to maintain consistency.
Special Notes:
- Temperature Limits: Do not exceed 260 °C (500 °F) during heating to avoid product degradation.
- Flash Point: > 270 °C (518 °F), indicating high thermal stability.
- Softening Point: Approximately 100 °C (212 °F), ensuring performance under high rooftop temperatures.
- Elasticity and Flexibility: The product exhibits over 1,000% elongation and more than 90% elastic recovery at 25 °C (77 °F), with successful low-temperature flexibility performance, making it suitable for climates with temperature fluctuations.
- UV Resistance: Not specified; typically, the adhesive layer is protected by the membrane and not exposed to UV.
- Packaging: Available in 11.35 kg (25 lb) and 22.7 kg (50 lb) solid blocks, packaged in boxes.
- Standards Compliance: Meets ASTM D 6152 requirements for SEBS-modified bitumen adhesives.
SOPRASPHALTE M is a high-performance adhesive component in SBS-modified bitumen roofing systems, offering excellent flexibility, adhesion, and thermal resistance. It must be applied with care to temperature and handling guidelines to ensure optimal performance and longevity of the roofing system.
