Description
All-purpose aluminium-coloured mastic composed of SBS modified bitumen and solvents.
UNITS PER SKID:
0.31L - 1200
0.81L - 480
Material Use:
SOPRAMASTIC ALU is a solvent-based, aluminium-pigmented mastic formulated with SBS synthetic rubber and bitumen. It is primarily used as a jointing mastic, caulking material, and joint filler in bituminous waterproofing systems. Its formulation ensures excellent compatibility with bituminous membranes and provides enhanced waterproofing and UV protection. The inclusion of leafing aluminium pigments offers superior resistance to ultraviolet light, while the high polymer content ensures long-term flexibility and elasticity.
System Components:
SOPRAMASTIC ALU is typically used in conjunction with bituminous waterproofing membranes as a complementary sealing and detailing component. It does not require a primer for most substrates due to its excellent adhesion properties. However, it should not be used as a pitch pocket filler. It is applied directly from 310 ml cartridges using a standard cartridge extruder.
Applications:
This mastic is suitable for use in roofing and waterproofing systems where sealing of joints, terminations, and penetrations is required. It is ideal for use on bituminous membranes and other compatible construction materials. SOPRAMASTIC ALU can be applied to damp surfaces, making it suitable for a variety of field conditions.
Application Details:
- Application Temperature Range: -10°C to 35°C (14°F to 95°F)
