ARALDITE® AY 111 / HARDENER HY 111

• Solvent-free, green and environmentally friendly product
• Suitable for application in all directions, including horizontal, vertical and top surface construction
• Good mechanical strength and aging resistance
• Good waterproof and chemical corrosion resistance
• Not affected by high temperature environment after curing
• No shrinkage after curing
• High strength, high elastic modulus
• The color difference of components is obvious, and the mixing quality is easy to control

• Stir Araldite® AY 111 and Curing Agent HY 111 separately to eliminate any sediment.
• Pour Araldite® AY 111 and Curing Agent HY 111 into the mixing container according to the following mixing ratio.
• Use a simple stirrer (such as a spatula, etc.) to stir slowly until the products inside and at the bottom of the mixing container are completely mixed and the color is uniform.
• During the construction time, apply the colloid evenly to the surface to be bonded.

The following data were determined using standard test methods on typical production batches.

Pretreatment

• The strength and durability of a bonded joint are dependant on proper treatment of the surfaces to be bonded.
• At the very least, 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.
• Abrading should be followed by a second degreasing treatment

Mechanical processing

• Specialist firms have developed metering, mixing and spreading equipment that enables the bulk processing of adhesive.

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 acetone are used for cleaning, operatives should take the appropriate precautions and, in addition, avoid skin and eye contact.

Storage

• ARALDITE®  AY 111 and Hardener HY 111 may be stored for up to 18-25°C for 24 months at room temperature provided the components are stored in sealed containers.

Handling Precautions

• Our products are generally quite harmless to handle provided that certain precautions normally taken when handling chemicals are observed.
• The uncured materials must not, for instance, be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be affected.
• The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection.
• The skin should be thoroughly cleansed at the end of each working period by washing with soap and warm water.
• The use of solvents is to be avoided. Disposable paper - not cloth towels - should be used to dry the skin.
• Adequate ventilation of the working area is recommended.
