- High strength and impact resistance
- Reaches handling strength in under 40 seconds
- Low viscosity adhesive is easily applied from the bottle
- Strong, durable and long lasting bond on a variety of substrates
What is 3M™ Scotch-Weld™ Instant Adhesive CA4?
3M™ Scotch-Weld™ Instant Adhesive CA4 is a clear, fast-setting adhesive designed for bonding plastics and rubber.
How does the adhesive work?
The adhesive works by creating an instant bond on contact with the surface, resulting in quick and easy assembly.
Is it safe to use around food or drinking water?
No, this product is not intended for use in situations where it will come into direct contact with food or drinking water.
What if I accidentally get some of the adhesive on my skin?
If you accidentally get some of the adhesive on your skin, remove any excess immediately and then wash thoroughly with soap and warm water. It may take several days for the glue to wear off naturally.
Q: Can I paint over parts that have been bonded using 3M™ Scotch-Weld™ Instant Adhesive CA4?
A: Yes! Once fully cured (typically within minutes), this adhesive can be painted over without affecting its strength or performance.
3M™ Scotch-Weld™ Instant Adhesive CA4 is a glue that is easily applied with a thin bond line from a squeeze bottle and cures quickly. This cyanoacrylate adhesive is dispensed from a flexible container; pinch a precise drop or squeeze for a steady bead.Recommended Applications
- Gasket attachment
- Small Joint assembly
- Jewelry assembly
- Orthopedics and footwear
3M™ Scotch-Weld™ Instant Adhesive CA4 typically reaches handling strength in under 40 seconds, with a full cure achieved in 24 hours. This keeps jobs moving quickly and may help improve workplace productivity. Once a full cure is achieved, the glue achieves a strong, durable and lasting bond, with overlap shear strength over 2,000 psi.Understanding Instant Adhesives
Instant adhesives are cyanoacrylate based formulas that are strong, fast-acting glues used in industrial and household applications. In general, they are an acrylic resin that rapidly polymerizes in the presence of moisture, forming long, strong chains, joining the bonded surfaces together.
Cyanoacrylate adhesives should be applied thinly, with pressure put on the bond for a few seconds, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time.
3M instant adhesives apply right from the container and rapidly reach handling strength at room temperature. Commonly referred to as a super glue, a single drop per square inch can bond many plastics, rubbers, metals, wood and more. An instant adhesive from 3M set a Guinness World Record in 2012 for the strongest glue by lifting an 8.1 metric ton forklift in the air for one hour.Bringing Better Ideas to the Surface through Science and Innovation
