• 10-minute open time at RT
• Gap filling up to 30 mm
• Bright grey color (UV stable)
• Tolerant to ‘’less than ideal’’ pretreatment
• Tough flexible bonds for use in dynamic environments

• Because of the high viscosity of the product, it is recommended to use a pneumatic dispensing gun.
• To ease the use with a manual dispensing gun, the cartridges can be preheated at 40°C during minimum 1 hour, if possible 2 hours before use.
• The resin/hardener mix may be applied manually or robotically to the pretreated and dry joint surfaces.
• A layer of adhesive 0.25 mm thick will normally impart the greatest lap shear strength to the joint.
• The joint components should be assembled and secured in a fixed position as soon as the adhesive has been applied.

Pretreatment

• The strength and durability of a bonded joint are dependent on proper pretreatment of the surfaces to be bonded, however the methacrylate adhesives can be used effectively with little surface preparation.
• Ideally joint surfaces should be cleaned with a good degreasing agent such as acetone, iso-propanol (for plastics) or other proprietary degreasing agents in order to remove all traces of oil, grease and dirt.
• Low grade alcohol, gasoline (petrol) or paint thinners should never be used.
• The strongest and most durable joints are obtained by either mechanically abrading or chemically etching (“pickling”) the degreased surfaces.

Equipment Maintenance

• All tools should be cleaned with hot water and soap before adhesives residues have had time to cure.
• The removal of cured residues is a difficult and time-consuming operation.
• If solvents such as MEK are used for cleaning, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact.

• Cure 24 hours at 23°C (73°F) – per ISO 9142/E2.
• Tested at 23°C (73°F).
• Metals: sandblasted and degreased;
• Plastics: abraded and degreased.

Average lap shear strength (ASTM D3163), plastic-plastic joints. Substrates were lightly abraded and degreased with IPA.

• Lap shear strength (ASTM D1002) versus heat ageing and thermal cycling (typical averagevalues).
• Cured 7 days at 23°C (73°F). Tested at 23°C (73°F).
• Thermal cycling 100 cycles: 2h at -30°C(-22°F) → 1 h ramp up to 70°C (158°F) → 2h at 70°C (158°F) → 1h ramp down to -30°C (-22°F))

Lap shear strength (ASTM D1002) versus tropical weathering (ISO 4587) (typical average values) Aging at 40°C / 92% RH. Cure: 7 days at RT. Test at 23°C (73°F)

Lap shear strength versus immersion in various media (ASTM D1002) (typical average values). Cured 7 days at RT Tested at 23°C (73°F). Lap Shear Strength was determined after immersion for 30,60 and 90 days at 23°C (73°F).

• Substrates degreased with IPA.

Lap shear strength (ASTM D1002) versus temperature (typical average values). On aluminium, pre-treatment: sand blasting. Cured 24 hours at 23°C (73°F).

• ARALDITE® 2023-10 A/B Adhesive should be stored in a dry place, in the original sealed containers, at temperatures between 2°C to 8°C (36°F to 46°F).
• Under these storage conditions, the product has a shelf life of 24 months from date of manufacturing.
• The product should not be exposed to direct sunlight.
• The product may be placed at room temperature before use, the total time at room temperature should not exceed 6 months.
• Long term exposure above 25°C will reduce the shelf life of the product.
• The product should be never frozen.
