When it comes to adhesives, there are a multitude of options available in the market. Two commonly used adhesives are rubber cement and contact cement. Both adhesives have their own unique properties and characteristics, making them suitable for different projects. In this article, we will compare rubber cement and contact cement, their differences, similarities, and when to use them.
Rubber Cement
Rubber cement is a popular adhesive that is widely used in craft projects, office applications, and home improvement tasks. It is made by combining natural or synthetic rubber with several solvents like acetone or hexane. The adhesive has a liquid texture that dries into a rubbery consistency.
Pros
1. Versatile: Rubber cement can be used on many surfaces, such as paper, fabric, leather, or plastic.
2. Easy to use: Rubber cement is easy to apply to surfaces as it comes with a brush applicator.
3. Easy clean-up: If applied correctly, rubber cement can be easily peeled off surfaces without leaving any residue.
4. Safe: Rubber cement is generally considered a safe adhesive as it contains fewer harmful chemicals.
Cons
1. Slow drying time: Rubber cement takes longer to dry, usually between 10-15 minutes.
2. Not waterproof: Rubber cement is not suitable for outdoor use or projects that require water resistance.
3. Flammable: The solvents used in rubber cement make it highly flammable, so it should be kept away from heat or fire.
Contact Cement
Contact cement is also a popular adhesive used in construction, woodworking, and automotive industries. It is made by blending rubber, neoprene, or synthetic resin with several solvents like heptane or toluene. When applied, the adhesive creates a strong, permanent bond between two surfaces.
Pros
1. Fast-drying: Contact cement dries quickly, usually between 10-20 minutes.
2. Strong bond: Once applied, contact cement forms a strong, permanent bond between surfaces.
3. Waterproof: Contact cement is resistant to water and can be used for outdoor projects.
Cons
1. Messy: Contact cement is usually applied with a brush, making it messy to use. It also has a strong odor that can be unpleasant for some users.
2. Toxic: Contact cement contains several toxic chemicals that can be harmful to the environment and human health.
3. Difficult to remove: Once applied, contact cement is challenging to remove, and it can damage surfaces if not done correctly.
Rubber Cement Vs Contact Cement: Which One to Choose?
The choice between rubber cement and contact cement depends on the type of project you are working on. Here are a few factors to consider before selecting an adhesive:
1. Nature of the surface: Rubber cement is more suitable for porous surfaces like paper or fabric, while contact cement is better suited for non-porous surfaces like metal or plastic.
2. Drying time: Rubber cement takes longer to dry, while contact cement dries quickly. If you need to finish a project quickly, contact cement may be a better option.
3. Water resistance: If you are working on an outdoor project or an item that needs to be water-resistant, then contact cement is the better choice.
4. Clean-up: Rubber cement can be easily peeled off surfaces, making it easy to clean up. Contact cement is challenging to remove without damaging the surface.
FAQs
1. Can rubber cement be used on metal surfaces?
Yes, rubber cement can be used on metal surfaces as well. However, it is not the best option for non-porous surfaces.
2. Can contact cement be used on fabric or paper?
No, contact cement is not recommended for use on fabric or paper as it can bleed through the material and damage the surface.
3. Is rubber cement safe to use?
Rubber cement is generally considered a safe adhesive as it contains fewer harmful chemicals. However, it should be used in a well-ventilated area, and users should avoid prolonged exposure to the fumes.
4. How long does contact cement typically last?
Contact cement has a long shelf life and can last for several years if stored correctly. Once applied, the adhesive can last several years, depending on the conditions of the environment.
Conclusion
Both rubber cement and contact cement have their advantages and disadvantages, making them suitable for different projects. Rubber cement is a versatile adhesive that can be used on many surfaces, while contact cement forms a strong, permanent bond between surfaces. As with any adhesive, it’s essential to read the instructions carefully, use it in a well-ventilated area, and avoid prolonged exposure to the fumes to ensure safe and effective use.
