In the competitive world of construction and facade engineering, the choice of sealant can determine the success or failure of a project. Wacker GN Silicone Sealant is a premium-quality, one-component, neutral-cure silicone designed to meet the rigorous demands of modern architecture.
Whether you are sealing high-end aluminum windows, glass facades, or interior expansion joints, Wacker GN offers the perfect balance of strength, flexibility, and ease of use. At Poly Prime Industry, we understand that professionals in Delhi need more than just a product—they need a guarantee of performance. That is why we maintain ready stock of genuine Wacker GN, providing a reliable backbone for construction projects across the NCR.
The most significant feature of Wacker GN Silicone Sealant is its Neutral Cure (Alkoxy) formulation. Understanding the difference between Neutral and Acetic (Acid) cure is vital for any professional:
Traditional acetic sealants release acetic acid during curing, which can corrode metals and damage the silver backing of mirrors or the coating on high-performance glass. Wacker GN is non-corrosive. It is chemically inert, making it 100% safe for use on sensitive materials like:
Anodized and Powder-Coated Aluminum
Galvanized Steel and Copper
Coated Glass and Mirror Backing
Sensitive Natural Stones
Because it doesn’t release acidic vapors, Wacker GN Silicone Sealant has a very low odor. This makes it ideal for indoor applications in confined spaces, such as luxury interior fit-outs, where a strong chemical smell would be unacceptable.
Wacker GN is engineered to survive the toughest outdoor conditions. It is highly resistant to:
Ultra-Violet (UV) Radiation: It won’t yellow or become brittle under the harsh Delhi sun.
Ozone and Oxidation: It maintains its rubbery texture even after decades of exposure to air pollutants.
Temperature Extremes: Once cured, Wacker GN remains flexible in temperatures as low as -50°C and as high as +150°C, ensuring the seal never fails during seasonal shifts.
Wacker GN provides “primerless” adhesion to a wide variety of surfaces. It creates a molecular bond with:
Glass and Glazed Surfaces
Aluminum (Anodized, Painted, or Raw)
UPVC Frames
Ceramic Tiles and Vitrified Tiles
Various Metals and Coated Substrates
The thixotropic nature of Wacker GN means it is a thick, stable paste that won’t flow out of the joint. This allows for clean, precise application on vertical joints (like window perimeters) and overhead joints (like skylights) without any slumping or mess.
The versatility of Wacker GN Silicone Sealant makes it a “must-have” for several industries:
It is the standard choice for perimeter sealing. It fills the gap between the window frame (Aluminum or UPVC) and the masonry wall, providing a flexible, airtight, and watertight barrier.
In modern glass buildings, Wacker GN acts as a vital weatherseal, protecting the structural components from moisture ingress and allowing the glass panels to move safely during high winds.
Buildings naturally shift due to thermal expansion and seismic activity. Wacker GN’s high elasticity allows it to stretch and compress within these joints, preventing cracks in the building’s exterior.
From sealing bathroom fixtures to filling gaps in premium interior woodwork, its neutral nature and clean finish make it perfect for high-end residential and commercial interiors.

To ensure the longevity of your Wacker GN Silicone Sealant, Poly Prime Industry recommends following these professional steps:
Cleaning: The surface must be dry and free of dust, grease, and old sealant. Use a “Two-Wipe” method with a clean, lint-free cloth and a solvent like Isopropyl Alcohol (IPA).
Masking: Use masking tape on the edges of the joint. This ensures that any excess silicone doesn’t stain the surrounding area and results in a perfectly straight line.
Application: Cut the nozzle at a 45-degree angle. Apply steady pressure to the caulking gun, ensuring the sealant fills the entire depth of the joint to avoid air pockets.
Tooling: Tool the sealant immediately (within 10 minutes) using a spatula or a tooling tool. This presses the silicone into the joint for maximum adhesion.
Curing: Allow the sealant to cure undisturbed. It will form a “skin” quickly, but full deep-cure takes 24-48 hours depending on the thickness.

Q1. What is the main difference between Wacker GN and Wacker GP?
Wacker GP is an Acetic (Acid) cure sealant, which is cheaper but can corrode metal and has a strong smell. Wacker GN Silicone Sealant is a Neutral cure sealant, which is safe for all metals, has no bad smell, and is superior for professional construction and facade work.
Q2. Is Wacker GN Silicone Sealant suitable for structural glazing?
While Wacker GN is an excellent weatherseal and glazing support sealant, for primary “structural” bonding (where the silicone holds the weight of the glass), we recommend using Wacker SG79.
Q3. Can Wacker GN Silicone Sealant be used on concrete and stone?
Yes. Because it is neutral-cure, it has excellent adhesion to porous surfaces like concrete and brickwork without the risk of chemical reaction.
Q4. Where can I find a bulk supplier of Wacker GN Silicone Sealant in Delhi?
Poly Prime Industry is your trusted wholesale partner. We maintain significant stock at our Delhi warehouse for immediate dispatch.
Don’t risk your project’s integrity with low-quality, local sealants. Choose the German-engineered reliability of Wacker GN Silicone Sealant. It is the ultimate investment in the durability and safety of your building.
