Lapox Ultra Fast — bonds in 5–10 seconds, no mixing, no clamping.

Lapox Ultra Fast is a single-component ethyl cyanoacrylate instant adhesive. One drop bonds plastics, metal, rubber, glass, and ceramics on contact — no mixing, no clamping.

It set a PVC plumbing joint in Kavi Nagar in under 5 seconds and an acrylic display unit in Mohan Nagar in under 10. As of August 2026, a 50 g bottle is ₹81.42 incl GST from our Ghaziabad warehouse.

Which Project Should You Use Lapox Ultra Fast For?

Ultra Fast is for close-fitting joints on small parts. If the surfaces fit tight, it is the fastest bond you can buy. If there is a gap to fill, you need a paste or two-part epoxy.

How much does Lapox Ultra Fast cost?

How fast does Lapox Ultra Fast cure?

5–10 seconds on most surfaces at 25°C — under 5 seconds on PVC, under 8 seconds on metals, under 10 seconds on acrylic. Full lap shear of 130 kg/cm² develops over 24 hours.
