Soudal Universal Silicone, Black, 280 ml

Acetate universal silicone sealant universally applicable for construction and structural joints in interior and exterior, sanitary applications, etc. It can be used on most substrates except plastics. Permanently flexible, color-stable sealant with long-lasting durability and resistance to UV rays.

Characteristics of Soudal universal silicone:

• Color: black,
• Packaging: cartridge 280 ml,
• very easy to use,
• color-stable, UV resistant,
• permanently elastic after curing,
• very good adhesion to many materials,
• typical acetic smell.

Examples of use of Soudal universal silicone:

• Glazing work,
• sealing construction and building joints,
• sealing cold storage and containers,
• sealing air conditioning systems.

Technical data of Soudal universal silicone:

• Base Polysiloxane.
• Consistency paste.
• Curing system moisture.
• Skin formation (20 °C/65 % r.h.) about 7 minutes.
• Curing speed (20 °C/65 % r.h.) 2 mm/24 hours.

Substrates:

Suitable surfaces: all common surfaces except for PVC, PE, PP, PTFE and bitumen-based substrates. Surface condition: clean, dry, free of dust and grease. Preparation: porous materials should be primed with Primer 150, non-porous materials do not need treatment. Always recommended to perform a preliminary compatibility test.

Joint size:

Minimum width: 5 mm. Maximum width: 30 mm. Minimum depth: 5 mm. Recommendation: joint depth = ½ joint width. To limit joint depth and prevent the sealant from adhering to its bottom, always use a non-sticking material, e.g. PE sealing cord.

Application procedure:

Application: using a gun (manual or pneumatic). Working temperature: +5 °C to +35 °C. Cleaning: before curing with White Spirit (paint thinner) or acetone, after curing mechanically and with Soudal Silicone Remover. Adjustments: before skin formation with a Sealant spatula and Soudal surface smoother for sealants or soapy water. Repairs: Universal silicone.

Notes:

Due to its acetate nature, it may react with certain metals (copper, lead). Do not use this sealant for sealing natural stones such as marble, etc. For these applications, use Silirub MA. Avoid contact of this sealant with the primary glazing sealant of insulating double glazing or PVB film of safety glass.
