SA Sealproof Silicone Sealant

Uses

• Glazing applications (in-shop and field glazing of curtain wall modules)
• Sealing joints in metal, masonry, concrete, coated surfaces, plastics, and wood assemblies
• Weatherproofing butt joints and lap shear joints subject to movement
• Creating primary or secondary seals against water, air, and dust penetration in glazing and curtain-wall assemblies

Benefits

• Provides a long-lasting, durable seal that withstands harsh weather conditions
• Accommodates high joint movement without compromising seal integrity
• Excellent adhesion to various substrates, often without the need for primer
• Resists UV degradation, maintaining its properties over time
• Easy to apply and tool
• Environmentally friendly with low VOC emissions

Application Guide

1. Prepare surfaces by ensuring they are clean, dry, and free of contaminants.
2. Cut the nozzle at a 45-degree angle to achieve the desired bead width.
3. Apply sealant using a sealant gun, maintaining even pressure and consistent bead size.
4. Tool the sealant within 20-30 minutes to ensure proper adhesion and a smooth finish.
5. If needed, clean up uncured sealant with mineral turpentine.

Limitations

• Not recommended for continuous water immersion.
• Not suitable for porous surfaces like marble or limestone.
• Avoid use in totally confined spaces as sealant requires atmospheric moisture to cure.
• Cannot be painted over.
