Choosing the right adhesive for your project can be the difference between success and failure.
Whether you are working on a project or tackling professional repairs, selecting the right adhesive is key to achieving a strong, lasting bond. With so many options available, from epoxy adhesives to silicone sealants, how do you know which one is right for you?
This guide will walk you through the most common types of adhesives used in construction, maintenance and professional repairs, helping you make an informed decision.
What Are the Different Types of Adhesives?
The world of adhesives is vast. Let us explore some of the most common types, how they work and when to use them:
1. Epoxy Adhesives: Strong and Durable
Epoxy adhesives are among the strongest bonding agents, known for their ability to bond a wide variety of materials. They are commonly used in automotive repairs, metal bonding and heavy-duty construction applications.
Key Uses:
- Automotive repairs
- Ceramic and stone restoration
- Underwater repairs
At Astral Adhesives, we offer a wide range of epoxy adhesives. Our Bondtite Super Strength provides a longer working time and is designed for demanding jobs requiring high strength, such as construction and structural repairs.
2. Silicone Sealant: Flexible and Waterproof
Silicone sealant is perfect for areas that require flexibility and resistance to weather conditions, such as bathrooms, kitchens and outdoor applications. It is waterproof and can withstand temperature changes.
Key Uses:
- Window seals
- Weatherproofing outdoor fixtures
Our Astral Resibond General Purpose GP-100 is a high-performance silicone sealant designed for versatile indoor applications. With excellent adhesion to various surfaces like glass, metal and wood, it ensures long-lasting bonds. It withstands joint movement, making it ideal for gap filling and sealing. Its superior temperature resistance (-20°C to 150°C) and compliance with RoHS standards make it perfect for general-purpose sealing needs.
3. Epoxy Putty: Quick and Versatile
Unlike liquid epoxies, epoxy putty is a moldable material that is great for repairs and gap filling. It is often used in plumbing repairs and for bonding metal, wood and plastic. Our Astral Bondset Fast Setting is a versatile, high-strength epoxy putty that sets quickly for reliable repairs. With a compressive strength over 400 kg/cm² and resistance to acids and fungi, it is suitable for quick, durable fixes.
4. Water Pipe Glue: Strong Bonds for Plumbing
Water pipe glue is specially formulated for plumbing applications, ensuring leak-proof connections in PVC and other pipe systems. It is easy to apply but requires fast action once the glue is on.
Key Uses:
- Plumbing connections
5. Wood Glue: Perfect for Furniture Projects
Wood glue is essential for woodworking projects. It forms a strong bond between wooden surfaces and ensures a neat finish. Different types of wood glue are available for indoor or outdoor use, with some offering water resistance.
Key Uses:
- Furniture making
- Cabinet construction
Our Astral Bondtite Multibond SR is a synthetic rubber-based wood glue, designed for versatile bonding applications. Ideal for industries such as footwear, electronics, automotive interiors and HVAC, it offers excellent bond strength. It ensures durable connections across diverse substrates.
Selecting the best adhesive comes down to the type of materials you are bonding and the environmental conditions the bond will face. For structural repairs, epoxy adhesives are best, while silicone sealant is ideal for areas needing waterproofing and flexibility.
