LOCTITE 4902 - 20g (cyanoacrylate adhesive (instant), colorless/transparent, flexible)
Product description:
LOCTITE® 4902 is a highly flexible cyanoacrylate adhesive designed for the assembly of flexible medical devices. This product facilitates the use of dissimilar and opaque substrates while improving device performance. LOCTITE® 4902 offers significant performance enhancements compared to standard cyanacrylates, including strength in flexing bond lines and resistance to leaks with excellent sealing capability. Known performance advantages of cyanoacrylates are maintained,including speed, ease of use and strength. Further information about the product: biuro@woronko-kleje.pl
Steps to achieve the best adhesive results:
1. Bond areas should be clean and free from grease. Clean all surfaces with a LOCTITE SF 7063 cleaning solvent and allow to dry.
2. To improve bonding on low energy plastic surfaces, LOCTITE SF 770 Primer may be applied to the bond area. Avoid applying excess Primer. Allow the Primer to dry.
3.Activator LOCTITE SF 7455 may be used if necessary. Apply it to one bond surface (do not apply activator to the primed surface where Primer is also used). Allow the Activator to dry.
4. Apply adhesive to one of the bond surfaces (do not apply the adhesive to the activated surface). Do not use items like tissue or a brush to spread the adhesive. Assemble the parts within a few seconds. The parts should be accurately located, as the short fixture time leaves little opportunity for adjustment.
5. Activator LOCTITE SF 7455 can be used to cure fillets of product outside the bond area. Spray or drop the activator on the excess product.
6. Bonds should be held fixed or clamped until adhesive has fixtured.
7. Product should be allowed to develop full strength before subjecting to any service loads (typically 24 to 72 hours after assembly, depending on bond gap, materials and ambient conditions).
8. This product performs best in thin bond gaps (0.05 mm / 2 mil ).
Storage:
Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling.
Optimal Storage: 2 °C to 8 °C. Storage below 2 °C or greater than 8 °C can adversely affect product properties.
Material removed from containers may be contaminated during use. Do not return product to the original container.
Henkel Corporation cannot assume responsibility for product which has been contaminated or stored under conditions other than those previously indicated.
