SikaFast®-2590

2-component universal Super Glue

SikaFast®-2590 is a fast curing and gap-filling two-component Universal “Super Glue”, based on ethyl-cyanoacrylate technology. It offers a long open time combined with fast curing. Due to its viscosity SikaFast®-2590 is well suited for vertical and overhead applications.  

  • Wide adhesion range
  • Gap filling up to 5 mm
  • Can be grinded and painted
  • High strength and good shock absorbing properties
  • Bonds porous materials (wood, cork, leather)
  • Low blooming and low odor

PRODUCT BENEFITS

  • Wide adhesion range
  • Gap filling up to 5 mm
  • Can be grinded and painted
  • High strength and good shock absorbing properties
  • Bonds porous materials (wood, cork, leather)
  • Low blooming and low odor
 

Areas of Application

SikaFast®-2590 is designed for quick repairs or bonding of a broad variety of materials, even with irregular surfaces. Due to the good gap-filling properties SikaFast®-2590 can be used for re-construction of broken pieces as well as to fill cracks.  Alternatively it can be used to strengthen weak parts or be used as chemical anchoring of e.g. small screws and hooks. Seek manufacturer’s advice and perform tests on original substrates before using SikaFast®-2590 on materials prone to stress cracking. This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

Technical Information

CURE MECHANISM

SikaFast®-2590 cures by polymerization when mixed.

The open and handling time are influenced by adhesive thickness, substrate surface and temperature, e.g. as higher the temperature as shorter the open and fixture time and vice versa.

CHEMICAL RESISTANCE

In the view of potential chemical or thermal exposure, it is required to conduct a project related testing.

Application

Application Information

Surface preparation

Surfaces must be clean, dry and free from grease, oil and dust. Remove all loose particles or residues by cleaning it thoroughly, for example with an IPA wipe.
Due to the diversity of materials, preliminary tests with original substrates are necessary.

Application

SikaFast®-2590 is applied with a mixing ratio of 4 : 1 by volume through a static mixer.

Consider that if applied in large masses, heat is generated by the exothermic reaction. The mixed adhesive has an open time of approx. 4 minutes and achieves handling strength in approx. 2 - 4 minutes after joining on thin layer applications. Optimum temperature for the bonding process is between 15 °C and 25 °C. The influence of the reactivity by temperature changes has to be respected.

After the open time has elapsed the bonded parts must not be moved against each other anymore. When the handling time is reached the parts can be moved if no additional stress is distributed to the bond line.

Removal

Uncured excess of SikaFast®-2590 can be removed easily before curing with a dry wipe, with Sika® Remover-208 or another suitable solvent. Once the adhesive is cured it can only be removed mechanically.
Hands and exposed skin shall be washed immediately using Sika® Cleaner-350H towels or a suitable industrial hand cleaner and water.

Do not use solvents on skin.
