Name:Adhesive for diamond pellet
Technical parameters:
       It is a double-component epoxy resin glue
 with its property improved. It is featured for 
strong adhesion, waterproof, quick hardening. It
 can be used for self-bonding and mutual bonding 
between materials, such as glass, metal, plastic 
and ceramic. It is suitable for bonding between 
diamond pellets and basic mould.

1
Appearance
Component A is a white thick paste
Component B is a silver gray thick paste
2
Anti-shear strength
>100 kg/cm2
3
High and low temperature
At high temperature of 80℃, glue layer remains the same after 2 hours
At low temperature of –40, glue layer remains the same after 2 hours
4
Hardening speed
25℃: A: B = 3: 1; 3 hours
18℃: A: B = 3: 1; 5 hours
5
Anti-alkali property
After dipping in coolant for 360 hours, the anti-shear strength is not lower than 60% of initial strength.
 
Usage and precautions:
 
(1)   Clean the parts to be adhered with gasoline or acetone.
(2)   A : B = 3 : 1 (in volume). After evenly mixed, it is used for the bonding between mould and pellets.
(3)   When removing the bonding, put the mould on the electric hot plate to heat it to about 100℃, then remove the pellets and clean off the bonding layer.
(4)   The adhesive can be prepared in wide range, good result can be obtained at the ratio of A : B = 2.5 – 3.5 : 1(in volume). The recommended ratio is A : B = 3 : 1(in volume). Hardening can be quickened up by increasing the amount of A component or the temperature.
(5)   The adhesive should be stored in a dry and cool place. It should be covered closely after use. The storage period is 12 months.
