Contact adhesive, also known as contact cement is a widely used bonding solution in manufacturing, construction, and everyday applications. It has unique characteristics compared to other common adhesives. In this article, we will explore what contact adhesive is, how it works, and the most common ways it is used across different industries. Now, let’s dive in.
What is Contact Adhesive
A contact adhesive glue, the most popular in the market currently, is an organic solvent applied to surfaces to create a flexible and permanent bond. Because of the quick evaporation of a flammable solvent, this contact glue dries fast but keeps sticky, which makes it an excellent adhesive for gluing together materials that are nonporous.
Contact adhesive plays a key role in applications where need to bond large areas and dissimilar materials. From laminates and rubber to leather and metals, it guarantees complete accuracy and conjoin substrates permanently.
Features of Contact Adhesive
Like any bonding solution, contact glue comes with both advantages and limitations. Here are the main features of it:
| Features of Contact Adhesive | ||
|---|---|---|
| Advantages | Fast drying: Contact adhesive forms a strong bond immediately when two coated surfaces are pressed together | |
| Versatility: Contact adhesives can bond a wide range of materials, including rubber, leather, fabric, wood, plastics, and certain metals. | ||
| High strength: Initial bonding strength reaches 0.8 MPa,and tensile shear strength can reach 2.79 MPa. | ||
| Resistance: Contact adhesive has the good cold resistance, moisture resistance, easy to use. | ||
| High cost-effectiveness: It is especially effective for bonding large, flat surfaces, and the amount of glue used per unit area is more economical. | ||
| Disadvantages | Not adjustable: Once the two surfaces make contact, the bond forms immediately, no room for adjustment. | |
| Surface Preparation: improper surface preparation will reduce the bond strenght of contact adhesive. | ||
| Solvent Odor: Contact adhesive has e a slightly irritating odor when not yet dry. | ||
| Using restrictions: Contact adhesive is forbidden to paste expanded polystyrene, plasticized polyvinyl chloride and some artificial leather. | ||
Where to Use Contact Adhesive
As mentioned earlier, contact adhesive can be used in almost all applications. It is often used in materials with high shear strength, good anti-vibration, perfect sealing performance, good insulation, excellent resistance to strong acid and alkali, high and low temperature resistance, oil – water resistance, aging resistance and so on.
Actually, construction and manufacturing industries have been using contact adhesives for many years. For example, you can bond together carpets, vinyl, leather, cardboard, rubber and various soft materials with this sort of adhesive. Besides. metal and other non-metal materials like aluminum, stainless steel, bricks, ceramics, some plastics, fabrics, glass, mirrors, etc.
How to Use Contact Adhesive to Bond Two Objects Together
1.Cleaning process: Clean the surface to be bonded and roughen it if necessary. Especially if you have used other glues before, be sure to clean it up thoroughly.
2.Apply glue evenly: Apply the glue evenly on the surface to be bonded. Note: The adhesive does not need too much. Otherwise, it will affect the bonding effect.
3.Drying glue: The airing time is about 15 minutes.If your touch the glue and feel very sticky, but the fingers will not stick to the glue, the surface is ready.
4.Align and paste: Align the adhesive surface, press it from one side of the adhesive surface to the other side, and use a cork hammer to apply pressure evenly from the center to the edge to drive out the air. The higher the pressure, the more uniform the bonding effect is.
5.Wait: 72 hours to reach maximum intensity.
