• Estimate the budget for the audit, including any costs associated with external consultants, travel, and material testing (if needed).

4. Communication Plan:

• Establish a clear communication plan outlining how information will be shared within the audit team and with relevant stakeholders in your company.

Data Collection: Gathering the Glue for Your Adhesive Audit

During an adhesive audit, data collection is critical for understanding your current adhesive usage and identifying areas for improvement. Here’s a breakdown of the key information to gather:

1. Adhesive Characteristics:

• Type and Chemical Composition:

  Identify the specific type of adhesive used for each application (e.g., epoxy, hot melt, or pressure-sensitive). Understanding the chemical makeup helps assess its properties and suitability for the application.

• Properties:

  Collect data on relevant adhesive properties like bond strength, flexibility, temperature resistance, moisture resistance, and chemical resistance. This data is typically found in the TDS and helps determine if the adhesive is meeting the demands of the application.

• Shelf life and storage conditions:

  Note the recommended shelf life of each adhesive and any specific storage requirements (e.g., temperature and humidity control). Improper storage can impact adhesive performance. Information on shelf life and storage can be found on the TDS or SDS (Safety Data Sheet).

• Safety Data Sheets (SDS):

  These documents provide important health and safety information about the adhesive, including potential hazards, handling precautions, and disposal methods.

2. Application Process:

• Application Techniques:

  Determine whether the adhesive is being applied manually or automatically by machinery. Each method has its advantages and limitations.

• Surface preparation procedures:

  Document the current procedures for preparing surfaces before adhesive application. Surface preparation is crucial for ensuring a strong bond.

• Curing Time and Conditions:

  Record the recommended curing time and any specific conditions required for the adhesive to fully cure and achieve its optimal strength.

• Amount of Adhesive Used:

  Track the typical amount of adhesive being used for each application. Overuse can be wasteful, and underuse can lead to weak bonds.

3. Performance Evaluation:

• Quality Control Data:

  Gather existing data from your quality control department related to bond strength and any reported adhesion issues for the targeted application(s). This data helps identify potential weaknesses in the current process.

• Customer Feedback:

  If applicable, consider incorporating customer feedback regarding product performance that might be related to adhesion. Customer concerns could indicate issues with the chosen adhesive or the application process.

Data Collection Methods:

• Document Review:

  Review existing technical data sheets (TDS), safety data sheets (SDS), quality control records, and production documents.

• Interviews:

  Conduct interviews with personnel involved in adhesive selection, application, and quality control to gain insights into current practices and potential challenges.

• Observation:

  Observe the adhesive application process firsthand to identify any potential inefficiencies or inconsistencies.

• Sample Testing (Optional):

  In some cases, additional testing of adhesive samples might be necessary to verify performance or explore alternative options.
