Superior Movement Capability (±50%): Exceptional accommodation of structural and thermal movement
Advanced UV Stability: No degradation, color change, or mechanical property loss with sun exposure
Extreme Weather Resistance: Performs in temperatures from -50°C to +150°C
Non-Staining Technology: Safe for use on natural stone and sensitive facade materials
Extended Service Life: 20+ year durability in properly designed joints
All-Weather Application: Can be applied in temperatures as low as -20°C

Application

Expansion and control joints in facade systems
Panel-to-panel joints in curtain wall assemblies
Perimeter sealing around windows and doors in facades
Weather sealing of pre-cast concrete panel joints
Connection joints between different facade materials
Weather sealing of EIFS and stucco systems

Applicable Materials

Glass and glazed surfaces
Anodized and painted aluminum
Natural stone (marble, granite, limestone)
Precast concrete and GFRC panels
Fiber cement boards
Most metals and composite panels
EIFS and stucco systems

Surface Preparation:

Surfaces must be clean, dry, and free from dust, grease, oil, and old sealant residues
For metals, clean with isopropyl alcohol
For porous substrates like concrete, use BoPin PR-140 Universal Primer
For stone facades, ensure surfaces are completely dry

Application Method:

Cut cartridge tip at 45° angle for desired bead size
Apply with consistent pressure using professional sealant gun
Fill joint completely from bottom to top to prevent air entrapment
Tool within 15 minutes using minimal tooling solution (dry or lightly soapy water)
Remove masking tape immediately after tooling

Joint Design:

Minimum joint width: 6mm
Maximum joint width: 40mm
Optimal width-to-depth ratio: 2:1
Minimum depth: 6mm even in narrow joints
Use backing material for deep joints
Design joint width to be at least 4 times anticipated movement

Limitation

Not suitable for structural glazing applications
Not recommended for continuous water immersion
Cannot be painted (use BoPin MS-240 for paintable applications)
Not suitable for traffic-bearing surfaces
Not recommended for PE, PP, PTFE, or direct contact with EPDM

Application

For high-rise applications, perform adhesion testing on actual project materials
In critical applications, conduct mock-up testing under project-specific conditions
For custom colors, contact BoPin technical support with RAL/Pantone reference
For wide joints (>25mm), apply sealant in multiple passes to ensure proper contact
In extremely hot or cold conditions, store sealant at moderate temperature before use
