Bondinsul 53A / 72B is an elevated curing epoxy system where Bondinsul 53A is an unmodified epoxy resin and Bondinsul 72B is a solid aromatic hardener. The B stage curing is induced at room temperature but requires elevated temperatures for full cure to its C stage. This system can provide thermal resistance up to 150 °C.
Stage wise production and increase in production capacity
Suitable for manufacturing electrical insulating composites
Step 1 : Reinforcement material is coated or impregnated with epoxy. Impregnated reinforcement material is then shaped and cured at room temperature to bind reinforment material together to achieve final product.
High mechanical strength
Good thermal properties
Good dielectric properties
Stage wise curing
Storage : Part A & B should be stored away from light & heat. Partly emptied containers should be tightly closed immediately after use to avoid exposure to light.
Shelf Life : "2 year from date of mfg. for both Part A and Part B (Storage Temp - 2-40 °C)"
