- General Information
This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials:
Directions for use:
1) This product is light sensitive; exposure to daylight, UV light and artificial light should be kept to a minimum during storage and handling.
2) For best performance bond surfaces should be clean and free from grease.
3) This product performs best in thin bond gaps (0.05 mm)
4) Excess adhesive can be dissolved with nitromethane or acetone.

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 mm 2 ) 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
TENSILE SHEAR STRENGTH
The shear strength will depend on the substrate. The Table below shows the shear strength for different substrates using lap shears according to ISO 4587.

Safety & Health
- Precautions
1. Avoid contact with skin and eyes.
2. If contact with skin, rinse with water.
3. If adhesive gets into eye, keep eye open and rinse with water thoroughly. Seek medical attention immediately.
4. 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.
