two component epoxy adhesive
A-Seal epoxy adhesive is a versatile and superior two component
epoxy resin adhesive, which has been specially formulated for applications
requiring high bond strengths. Resin AS-06 is a slovent free epoxy
resin,which cures at room temperature when mixed with Hardener HR-53.
Besides possesing extremely high resistance to empact stress,tensile
and shear strengths, A-Seal epoxy adhesive also has controlled flow
characteristics, which prevent it's flow during the curing process.
After curing, the bond is unaffected by water, humidity,solvents,
mild acids, alkalies etc.
A-Seal epoxy adhesive is therefore ideal for domestic, auto, marine,
industrial applications etc., where steel, iron, wood, glass, aluminium,
bronze, ceramics, asbestos, leather, rubber etc. are required to
be bonded to themselves or each other.
A few aplications where A-Seal epoxy Adhesive can be very advantageously
Assembly of speakers
Brass caps to electric lamps.
Bond sealing of traction motor armatures
Assembly of radios and transistors
Insulation and fixing decorative panels and other components.
Wooden and backelite cabinets.
Bonding Ferrite in magnetos etc.
Engineering Industeries Joining wooden or metal pattern parts.
Joining wooden and metal structural parts.
Grouting bolts in cement floor of machinery
Packing seals of geysers/boilers etc.
Fixing loose screws, bolts, textile reeds.
Fixing Aluminium labels on machines, fans and other products.
Repairing of many items made of metal ,ceramics, glass , plastic.
Repairing of sports goods and toys.
Fixing of loose stones in jewellery.
The surface to be bonded should be dry and free from dust, rust,
oil, grease, wax, paints etc. For removing surface deposits like
oil, grease, wax etc., use a suitable solvent or detergent solution.
Solvents such as acetone and detergent are good degreasing agents.
The strongest bonds are obtained if the surfaces to be bonded are
roughened, and is best carried out, after first degreasing the surfaces
using emery cloth, wire brushes or by sand blasting. This treatment
besides making the surface rough, removes all traces of rust, oil,
grease, wax, old paint etc. This should be followed by another thorough
degreasing. For joingig broken materials like China clay( cup, insulators,flower
vase etc.) wood and any other items which show arough surface after
breaking, abrasion is not necessary, but light wire-brushing may
be done to remove loose particles if any, followed by cleaning.
Rubber should be treated with concentrated sulphuric acid for about
5 minutes and after washing with water the surface should exhibit
minute cracks on flexing.
Care should be taken to ensure that the cleaned surfaces
are not dirtied or touched before the adhesive is applied. This
should be as soon as possible after preparation of the surface.
Mixing and application procedure
the Resin and Hardener thoroughly, with a spatula, metal or glass
rod, screw driver etc., in the above mentioned ratio. Apply a thin
film of the mixture to both the parts to be joined. As soon as the
adhesive has been applied, the joints should be held together with
a clamp, rubber band, a string or clips to ensure complete contact
pressure. Any excess adhesive can before wiped off befo the adhesive
has set. Immediately after use, clean hand with soap and water.
Tools should be wiped before A-Seal epoxy adhesive starts curing.
The curing time is dependent upon the curing temperature. The following
