SOUDAL SILIRUB EPDM Neutral Silicone Sealant Black 600ml EPDM Compatible

Product Overview

Soudal Silirub EPDM Neutral Black 600 ml is a low modulus, neutral-curing silicone sealant formulated for professional sealing and bonding applications in construction projects. Commonly used by contractors and installers for both interior and exterior joints, it provides strong adhesion to porous and non-porous substrates, including EPDM, brick, concrete, wood, aluminium, powder coatings, glass, PVC, acrylic, and plastics. Its thermal resistance ranges from -60°C to +180°C, accommodating demanding environmental conditions and ensuring stability under UV exposure.

What differentiates this SKU is its compatibility with EPDM rubber and a neutral cure formulation, which prevents corrosion of metal elements often seen with acidic sealants. This eliminates the risk of material degradation in multi-material facade or window assemblies, making it highly recommended for procurement by companies specializing in window installation, facade glazing, and industrial sealing where complex substrates or metal components must be protected.

Key Features

• Neutral-curing system ? eliminates corrosion risks for metal substrates, suitable for sensitive facade assemblies


• EPDM compatibility ? bonds effectively to EPDM rubber, allowing secure sealing in roofing and window installations


• UV-resistant joints ? maintains elasticity and structural integrity under continuous sun exposure


• Thermal resistance -60°C to +180°C ? usable in extreme climate zones or unheated spaces


• Elongation at break 800% (ISO 37) ? accommodates movement in expansion joints and flexible connections


• Elastic recovery >80% (ISO 7389) ? ensures durable flexibility for dynamic or vibrating structures


• Skin formation time approx. 5 min (20°C/65% RH) ? enables efficient workflow for installers
