Silicone Sealant for General purpose

This is a Knicker GP (General Purpose) Silicone Sealant, a high-performance adhesive and sealant designed for a variety of construction and DIY applications.

Key Specifications

Brand: Knicker

Type: 100% Acetic Silicone (Acetoxy cure)

Grade: General Purpose (GP) / High Tech

Form: Standard cartridge for use with a caulking gun

Core Characteristics

Acetic Cure: This is an "acetoxy" silicone, meaning it releases a vinegar-like smell while curing. It is known for fast drying times and excellent adhesion to non-porous surfaces.

Weather Resistance: Typically UV resistant and waterproof, making it suitable for both indoor and outdoor use.

Flexibility: Remains permanently flexible after curing to accommodate joint movement and thermal expansion.

Common Applications

This sealant is best suited for smooth, non-porous materials. Common uses include:

Glass & Glazing: Windows, doors, and aluminum frames.

Kitchen & Bath: Sealing sinks, backsplashes, and tiling (though check for anti-fungal properties if using in high-moisture areas).

General Repairs: Sealing gaps in gutters, vents, and air-conditioning systems.

Important Considerations

Note: Because this is an acetic silicone, it should not be used on alkaline surfaces (like concrete, fibrous cement, or plaster) or sensitive metals (like copper or brass), as the acid released during curing can cause corrosion or poor adhesion. For those materials, a "Neutral Cure" silicone is preferred.
