| Application Scope |
Suitable for manufacturing single-layer dyed solar films with good dye compatibility and moderate adhesion. |
| Usage Method |
– Resin/Curing Agent Ratio: 100g/0.8-2.0g<br>- Mixing Requirements: Weigh the diluent and dye first, then add the resin while stirring. After thorough mixing, add the curing agent and continue stirring until the solution is uniform in color and free of stratification.<br>- Dry Adhesive Amount: 10±2μm<br>- Drying Temperature and Time: 120℃, 30 seconds<br>- Curing Time: 24 hours (60℃) or 72 hours at room temperature<br>Note: Each coating factory must adjust the adhesive ratio appropriately due to differences in equipment conditions, oven temperatures, coating rollers, coating speeds, production environment temperature and humidity, base film quality, and curing time and conditions. |
| Precautions |
– Flammable material. Keep away from heat sources, avoid open flames, and prevent contact with eyes and skin.<br>- Install ventilation equipment near the machine and in the workshop to ensure the health of users and the environment.<br>- Seal the product promptly after use to prevent environmental contamination or moisture ingress, which may affect product quality.<br>- The product becomes more viscous over time after adding the curing agent. Use the adhesive in small quantities and multiple times as needed to ensure product quality.<br>- Conduct compatibility tests before using pigments.<br>- If the adhesive comes into contact with eyes, rinse immediately with plenty of water. Seek medical attention if discomfort persists. In case of accidental ingestion or excessive inhalation, seek medical attention immediately. |
