Our Adhesives and Sealants Range
What Are Adhesives?
Adhesives are bonding materials used to join two or more surfaces together. They provide a strong connection without the need for mechanical fasteners in many applications and are commonly used across manufacturing, construction, automotive and industrial environments.
Different adhesives are formulated for different materials and operating conditions. Choosing the correct adhesive helps improve bond strength, durability and long-term performance.
Common Materials That May Be Bonded
- Metal
- Aluminium
- Timber
- Plastic
- Composite materials
- Concrete
- Glass
Selecting the appropriate adhesive depends on the materials being joined, environmental conditions and the performance requirements of the project. For applications requiring flexible sealing as well as bonding, consider using polyurethane sealants.
What Are Sealants?
Sealants are designed to fill gaps, joints and openings to help prevent the passage of water, air, dust and other contaminants. Unlike adhesives, which primarily bond materials together, sealants are formulated to remain flexible and accommodate movement between surfaces.
Sealants are widely used in construction, automotive, transport and industrial applications where weather resistance, waterproofing and long-term flexibility are important.
Quality Sealants Can Help
- Prevent water ingress
- Reduce air leakage
- Protect joints from dirt and contaminants
- Absorb movement caused by vibration or expansion
- Improve the durability of finished installations
Selecting the right sealant helps ensure reliable sealing performance and long-term protection. For applications requiring flexible, high-performance sealing and bonding, explore our range of polyurethane sealants.
Adhesives vs Sealants
Although adhesives and sealants are often used together, they serve different purposes.
| Feature | Adhesives | Sealants |
|---|---|---|
| Primary Purpose | Bond materials together | Seal joints and gaps |
| Main Function | High bond strength | Flexible sealing |
| Flexibility | Generally lower | Higher flexibility after curing |
| Typical Use | Assembly and bonding | Waterproofing and joint sealing |
| Common Applications | Manufacturing, fabrication, construction | Construction joints, expansion joints, weather sealing |
Understanding the difference between adhesives and sealants helps ensure the correct product is selected for each application.

How to Choose the Right Adhesive or Sealant
Selecting the right product depends on your application, the materials involved and the environmental conditions the finished project will be exposed to.
Consider the Materials
Different adhesives and sealants are formulated for different substrates. Always choose a product that is compatible with the materials you are working with, such as metal, concrete, timber, plastic or glass.
Determine the Purpose
Ask whether you need to bond materials together or seal a joint.
- Choose an adhesive when the primary goal is to create a strong bond between surfaces.
- Choose a sealant when you need to fill joints or gaps to prevent water, air or dust from entering.
Consider Movement
If the joint is expected to expand, contract or vibrate, a polyurethane sealant may provide better long-term performance.
Indoor or Outdoor Use
Environmental conditions such as moisture, UV exposure and temperature changes should be considered when selecting a product.
Application Method
Choose a product that matches your preferred application method and project requirements.
If you're unsure which product is right for your application, the Top Fasteners team can help you choose the most suitable solution.
