 3M PRONTO™ INSTANT ADHESIVES
Fast bonding with the right combination of strength, cure time and viscosity.
These one-part cyanoacrylate adhesives rapidly reach handling strength at room temperature without a catalyst. On many applications, bonds reach handling strength
in 5–10 seconds and 80% of full strength in an hour. A single drop per square inch can bond many plastics, rubber, metal and more with tensile strength up to 5000 PSI.
Depending on the specific formulation, you have the following features: resistance to fuels, lubricating oils and other chemicals from -40°F to 200°F (-40°C to 93°C); gap filling; extended cure rates for repositionability; high peel and impact strength; conformance to MIL-Spec A-46050C.

A single drop of 3M™ Pronto™ Instant Adhesive
quickly bonds many plastics, rubber, metal
and more. |
To bond a flexible PVC mat into a high impact
polystyrene turntable, 3M™Pronto™Instant
Adhesive CA-40H provides high viscosity and
a slower set time to meet handling requirements. |
3M™ Pronto™Instant Adhesive CA-8 is an
excellent multi-purpose product for use in a
variety of assembly applications. |

Architectural pottery – For repair of fiberglass/
concrete cast pottery, 3M™ Pronto™ Instant
Adhesive CA-50 Gel bonds with high tensile
and shear strength. Non-sagging formulation
applies neatly when bonding curved surfaces. |
3M™ Pronto™ Instant Adhesive CA-40 works on many problem surfaces where other adhesives may fail, such
as bonding EPDM rubber. |
Veneer and wood repair – 3M™ Pronto™
Instant Adhesive CA-40H is a high viscosity
liquid for void filing between veneer and core.
A light spray of 3M™Pronto™ Surface Activator
over the adhesive before assembly accelerates
curing speed. |
