DOWSIL™ SILASTIC™ Q3-3636 Catalyst Black 25 KG

Product Overview

DOWSIL™ SILASTIC™ Q3-3636 Catalyst Black is the black-pigmented Part B curing agent for 2-part fast room-temperature curing (RTV) neutral silicone adhesive systems. When mixed with its corresponding Base component at specified ratios, it initiates a fast, homogeneous cure throughout deep joints independent of ambient moisture. Its black formulation delivers a clean, high-aesthetic finish for dark automotive and electronic assemblies.

Key Features and Benefits

• Fast & Controlled Cure: Rapidly accelerates curing reaction independent of atmospheric humidity when mixed with Base.
• Aesthetic Black Finish: High black pigmentation provides a seamless, professional appearance for dark assemblies.
• Industrial 25 KG Packaging: Designed for seamless integration with automated 2K meter-mix dispensing equipment.
• High Thermal & Weather Resistance: Imparts long-term thermal stability, UV, and moisture resistance to the cured elastomeric joint.
• Non-Corrosive Neutral System: Safe for sensitive electronics and metallic substrates.
