CURE SPEED vs. SUBSTRATE (non-UV/Vis cure)
The rate of cure will depend on the substrate used. The table below shows the fixture time achieved on different materials at room temperature. This is defined as the time at which an adhesive bond (250 mm2) is capable of supporting a 3 kg load for 10 seconds. Fixture time measurements relate to non-UV/Visible cure.Fixture Time (seconds)ABS 15 Acrylic 90 Polycarbonate 40 PVC 150 - Typical Performance Of Cured Material

Safety & Health
- Precautions
- Avoid contact with skin and eyes.
- If contact with skin, rinse with water.
- If adhesive gets into eye, keep eye open and rinse with water thoroughly. Seek medical attention immediately.
- Keep the material out of children’s reach.
Storage & Handling
- Storage
Keep adhesive in a cool and dry place. The storage temperature is recommended at 8°C - 24°C. Shelf life is twelve months from the date of manufacture in the original container under the optimal conditions.< /p>
