❓ Frequently Asked Questions
What can I use this glue for?
It works on many materials. Phone repairs and electronics are the primary use.
It also bonds leather, jewellery and watches. Use it for crafts and DIY projects.
A versatile adhesive used by both professional technicians and home users.
How long does it take to dry?
Initial set takes just a few minutes. You can handle items shortly after.
Full strength cure takes 24 hours. Avoid stress on the bond during curing.
Temperature affects dry time. Warmer conditions help the cure along faster.
Is this glue safe to use?
Yes. This glue is non-toxic with low odour. Safe for workshop use all day.
Still avoid skin contact when possible. Wash hands thoroughly after use.
Keep out of reach of children. Store sealed in a cool, dry location.
Why is it black coloured?
Black hides on dark surfaces. It blends with phone frames and rear panels.
It does not show on dark electronics repairs. Good for leather and dark materials.
Most phone repairs are on dark-coloured parts. Black adhesive is near invisible.
How do I apply it properly?
Clean both surfaces first. Remove all dust, oil and moisture.
Apply a thin layer using the needle tip. Less glue gives a stronger bond.
Press parts together firmly for 30–60 seconds.
Let cure for 24 hours for maximum strength before applying load.
What is the needle tip for?
The needle tip gives precision control over where the glue lands.
Apply tiny amounts to exact spots. No mess or wasted adhesive.
Essential for small phone parts, watch crystals and delicate repairs.
How much glue is in the bottle?
50ml capacity per bottle. You only need tiny amounts for each repair.
One bottle lasts many repairs. Great value for professional technicians.
How should I store this glue?
Store upright in a cool, dry place. Keep the cap tightly closed after use.
Avoid direct sunlight and heat. Both reduce shelf life.
Clean the needle tip after each use. Dried glue in the tip blocks flow.
Does it work on glass?
Yes. It bonds glass to many surfaces. Good for watch crystals and phone screens.
Clean the glass thoroughly before applying for a strong bond.
It works on most glass types used in phone and watch repairs.
Is it flexible when dry?
Yes. It stays flexible after drying. It does not crack or get brittle.
The bond moves with the material. Ideal for leather and items that flex.
Better than rigid adhesives for many everyday repair jobs.
