How to use

Surface Preparation:

Clean the bonding surfaces thoroughly – remove oil, grease, dust, rust, and other contaminants 
For best results, roughen glossy surfaces with sandpaper to improve adhesion
Ensure surfaces are dry before application
Mixing:

Dispense equal volumes of Main Agent (Pink) and Hardener (Light Yellow) 
Mix thoroughly until a uniform color is achieved (approximately 30-60 seconds)
Do not mix more than can be used within the pot life (30 minutes at 23°C) 
Application:

Apply the mixed adhesive to one or both surfaces
Assemble parts immediately after application
Apply firm pressure and fix in place
For best results, clamp or tape parts until initial set
Curing:

Pot life: 30 minutes at 23°C 
Handling strength: 1 hour at 23°C 
Full cure: 24 hours at 23°C 
Note: Lower temperatures extend curing time; higher temperatures accelerate curing
Storage:

Store in a cool, dry place away from direct sunlight
Recommended storage temperature: 5°C to 25°C
Keep containers tightly sealed when not in use
Shelf life: 12 months from manufacturing date when stored properly 
Safety Precautions:

Use in well-ventilated areas
Avoid contact with eyes and skin; wear protective gloves
If adhesive contacts skin, wash immediately with soap and water
If adhesive enters eyes, rinse with plenty of water and seek medical attention
Keep out of reach of children
Dispose of according to local environmental regulations
