CTWork Sealant, Dowsil 732 & 795, and Fevicol PUR Explained: Choosing the Right Sealant for Every Job
When it comes to home improvement, building maintenance, or industrial assembly, choosing the right sealant or adhesive is absolutely essential. With so many products available—like Dowsil silicone—it’s easy to get confused about which one suits which task.
In this detailed guide, we’ll explore the types of sealants and show you how to achieve professional sealing results every time.
Understanding the Role of Sealants
A sealant is a material used to fill gaps and joints between surfaces. Unlike adhesives—which mainly bond materials—sealants also provide elasticity, weather resistance, and protection against moisture.
Sealants are used in anywhere moisture or vibration must be controlled.
Common categories include:
Silicone sealants – Great for bathrooms, glass, and metal joints.
PU-based foam sealers – Known for strong bonding and flexibility.
Acrylic and hybrid sealants – Used in general construction.
Each type has unique strengths—so understanding them helps ensure your job lasts longer and looks cleaner.
2. CTWork Sealant: Reliable Performance for Professionals
CTWork silicone is a professional-grade product known for its strong adhesion and long-lasting flexibility.
It’s designed for interior and exterior use, making it perfect for general building maintenance.
CTWork sealant is also UV-resistant, mold-resistant, and fast-curing. Whether you’re working on a shower enclosure, aquarium, or façade, it delivers professional, clean results.
Why Use Polyurethane Foam?
Polyurethane foam is one of the most versatile sealing materials available. It’s a chemical compound that expands on contact with air that fills gaps, cracks, and voids.
Applications include:
Filling wall gaps and pipe penetrations
Thermal and acoustic insulation
Roof repairs and cavity filling
PU foam provides fast curing and easy trimming once hardened.
When paired with a quality sealant like CTWork or Dowsil, polyurethane foam creates a complete sealing system.
Silicone Mastic: The Flexible Sealer for All Surfaces
silicone adhesive is a go-to choice for bathroom, glass, and metal sealing. It’s ideal for wet environments, such as bathrooms, kitchens, and glass joints.
black-colored silicone sealant is commonly used in glass panels and kitchen designs because it creates a contrast-friendly appearance.
Benefits include:
Excellent UV and temperature resistance
Long-term elasticity
Adheres to metal, ceramic, and glass
Mold- and mildew-resistant
Silicone mastic’s ability to move with surfaces without cracking makes it a must-have for long-lasting seals.
Keep Water Out: The Best Shower and Bathroom Sealants
Bathrooms and showers are the toughest testing grounds for sealants.
A shower sealant must be formulated to resist soap and mildew.
Popular products include:
CTWork Bathroom Sealant – Ideal for tiles and glass panels.
Dowsil 732 or 795 – Industry-grade silicones for premium waterproofing.
Black silicone or clear neutral cure sealant – For stylish, invisible joints.
To apply:
Clean surfaces thoroughly.
Apply masking tape for neat edges.
Cut the nozzle at a 45° angle.
Apply a continuous bead and smooth it with a finger or tool.
This ensures a strong, leak-free bond that keeps your bathroom pristine for years.
Building or Repairing Aquariums with Silicone
When working with glass bonding under water exposure, only neutral cure clear silicone should be used.
Unlike general-purpose sealants, aquarium silicone is specifically formulated for underwater pressure and clarity.
CTWork, Dowsil 732, and Dowsil 795 are all trusted by professionals for marine glass sealing.
This specialized silicone provides:
Crystal-clear finish
Excellent adhesion to glass
Long-term waterproofing
Mold resistance
Professional-Grade Silicone from Dowsil
Dowsil 732 and Dowsil 795 (formerly Dow Corning) are two of the most reliable silicone sealants in professional construction and manufacturing.
Dowsil 732 Multi-Purpose Sealant
Ideal for metal, glass, ceramics, and plastics
High-temperature resistant
Excellent adhesion and flexibility
Commonly used in HVAC, automotive, and electronics sealing
Dowsil 795 Structural Glazing Sealant
Designed for architectural and façade applications
Superior UV, weather, and movement resistance

Both are neutral cure silicones, meaning they don’t corrode metals or damage sensitive materials, making them perfect for industrial, commercial, and residential projects alike.
Why Professionals Choose Fevicol PUR for Strong Bonding
Fevicol polyurethane adhesive is a high-performance bonding solution.
Unlike silicone sealants, Fevicol PUR is designed mainly for bonding rather than sealing. It offers strong adhesion on wood, metal, foam, and concrete.
Common uses:
Wood-to-wood and wood-to-metal joints
dowsil 732 Foam and panel bonding
Furniture manufacturing and interior design
Because it reacts with atmospheric moisture, Fevicol PUR forms a durable, waterproof bond ideal for structural or decorative work.
