Key Processes in Manufacturing
- Raw Material Procurement
- High-quality polymers, resins, and additives are sourced to formulate the adhesive. Materials undergo rigorous quality checks to ensure consistency and effectiveness.
- Adhesive Formulation
- The raw materials are blended in specific proportions to achieve desired properties such as bonding strength, flexibility, and curing time.
- Mixing and Homogenisation
- The ingredients are mixed using high-speed mixers to create a uniform adhesive. Homogenisation ensures consistency across batches.
- Heating and Processing
- The mixture is heated to activate chemical interactions, improving adhesive performance. This step is critical for solvent-based and polyurethane adhesives.
- Filtration and Quality Testing
- The adhesive is filtered to remove impurities and tested for performance metrics like viscosity, bonding strength, and drying time.
- Packaging
- The finished adhesive is filled into containers such as tubes, cans, or drums based on the target market. Proper packaging prevents contamination and maintains product quality.
- Labelling and Storage
- Packaged adhesives are labelled with usage instructions, safety guidelines, and branding before being stored in controlled environments to ensure stability.
