MATERIALS, ADHESIVES AND COATINGS
910, 101, 102, 105, 108, 170, 240, 268 general-purpose and metal cyanoacrylate adhesives (MIL-A-46050C, A-A-3097)
Country: United Kingdom · Model: 910 / 101 / 102 / 105 / 108 / 170 / 240 / 268
The one-component cyanoacrylate adhesives 910, 101, 102, 105, 108, 170, 240 and 268 polymerize in seconds under trace moisture and give a shear strength of 18–29 MPa. The methyl cyanoacrylates 910 and 170 are for metals, the ethyl cyanoacrylates 101–268 for plastics and elastomers. No mixing, heating or equipment is needed.

Description
The adhesive polymerizes at room temperature when it is squeezed into a thin film between parts, so in aviation it is used both to bond small parts and to instantly fix those that are then bonded with slower compounds. The original 910 is a 100 % methyl cyanoacrylate with a viscosity of 70–90 mPa·s for metals. Shear strength is 23–29 MPa on steel, 13–15 MPa on aluminum, 21 MPa on brass, fixture time about 10 s, hardness 85 Shore D, dielectric strength 25 kV/mm. The capillary version 910FS has 1–5 mPa·s. The ethyl cyanoacrylates give 18–25 MPa, and the viscosity of the 101 is 2–3 mPa·s, the 102 has 70–90 mPa·s, and the 240 has 1200–2500 mPa·s. Approvals: the 910 per MIL-A-46050C Type I Class 2 and CID A-A-3097 Type I Class 2, grades 101–268 per MIL-A-46050C Type II (classes 1–3).
How to choose
The substrate determines the choice. Metals are bonded with 910 or 170 with maximum gap filling, plastics with 101 and 102, elastomers with 105, and medium gaps with 108. Increased viscosity is found in the 240 and 268, and the 268 is fast-curing. For new designs follow A-A-3097 and ASTM D5363, while MIL-A-46050C is kept for existing designs. When a strength of 15–25 MPa with tolerance to surface preparation is needed, see the acrylate TA436.

FAQ
Which adhesive from the range should be used to bond steel and aluminum?
910 or 170. The 910 gives 23–29 MPa on steel and 13–15 MPa on aluminum and fixes in about 10 s.
How do the adhesives 101 and 102 differ?
Both are ethyl cyanoacrylates for plastics. The 101 is capillary (2–3 mPa·s), and the 102 has a viscosity of 70–90 mPa·s.
Which adhesive suits elastomers and medium gaps?
The 105 for elastomers, the 108 for medium gaps. The 108 is also listed in A-A-3097 Type II.
To which specification is the 910 adhesive approved?
To MIL-A-46050C Type I Class 2 for existing designs and CID A-A-3097 Type I Class 2 for new ones.
Are mixing or heating needed?
No. It is a one-component adhesive that polymerizes at room temperature, and a strong joint is obtained in seconds.
