Adhesive troubleshooting

Some common problems may be encountered when using adhesives. Here are some common problems and how to solve them:

1. Non-stick adhesive:

– Make sure the surface is clean: Clean the surface to be glued and make sure it is free of grease, dust or dirt. Use a cleaner or remover to clean the surface.

– Apply appropriate pressure: Before bonding, ensure that sufficient pressure is applied to make the adhesive fully in contact with the surface. Use a pressure tool, clamp, or weight to apply pressure.

– Ensure appropriate temperature: Some adhesives require a specific temperature range for optimal adhesion. Ensure that the ambient temperature meets the adhesive requirements.

2. The adhesive drying time is too long:

– Control ambient humidity: High humidity may prolong the adhesive drying time. Ensure that the humidity of the working environment is appropriate.

– Adjust the temperature: Some adhesives may take longer to dry at low temperatures. Using adhesives at the right temperature can speed up the drying time.

– Make sure the adhesive is not expired: Expired adhesive may affect its drying time. Check the expiration date of the adhesive and use fresh products.

3. Excessive flow or extrusion of adhesive:

– Control sizing: Use the right amount of adhesive, do not overapply or extrude. Apply the adhesive according to the amount recommended in the adhesive instructions.

– Adjust sizing pressure: For liquid adhesives, adjust sizing device pressure to control flow. Reduce pressure to reduce excessive flow.

4. Adhesive curing is not complete:

– Ensure appropriate environmental conditions: adhesive curing usually requires specific environmental conditions, such as appropriate temperature and humidity. Ensure that the adhesive is cured under appropriate environmental conditions.

– Increase curing time: Some adhesives may require longer curing times for optimal performance. Wait according to the recommended curing time in the adhesive instructions.

If the above solutions do not solve the problem, you are advised to consult the adhesive manufacturer or professionals for more specific advice and technical support.
