Description
Parasilico LMN Black Grey 7021 Silicone Sealant 300ml
Parasilico LMN Black Grey 7021 is a professional low modulus neutral cure silicone sealant for glazing, façade joints, frames, and exterior sealing. It gives a neat Black Grey RAL 7021 finish and stays permanently flexible after curing. DL Chemicals describes the LMN range as a 1-component neutral alcoxy curing silicone sealant for connection joints and façade joints.
Key Features
This sealant is designed for joints with movement and external weather exposure. DL Chemicals states that it offers excellent adhesion to almost all building materials, very good UV resistance, very good ageing resistance, and very good weather resistance. The official technical sheet also states movement capability of up to 20% for connection and façade joints.
Applications
Use this silicone for glazing joints, perimeter sealing, façade work, window frames, door frames, and general construction sealing. It is a strong option where you need a dark grey finish around aluminium systems, coloured uPVC, trims, and visible external joints. As a result, it works well for both new installations and repair jobs.
Colour Match
The Black Grey 7021 finish suits darker modern frames, cladding details, and perimeter joints where white, clear, or lighter grey sealant would not be the best match. DL Chemicals’ colour guide lists Black Grey as RAL 7021, which supports using both the colour name and RAL number in your listing for search coverage.
Pack Size Options
This product is supplied in a 300ml cartridge and can be sold as 1 tube or 25 tubes per box depending on how you want to structure the listing. Apply it to clean, dry, dust-free surfaces with a standard sealant gun. Smooth the bead before skinning begins, and test first on unfamiliar surfaces.
