| Cracking-resistant Toughening Curing
Agent, Polysebacic Anhydride(PSPA) 1. Brief
Introduction:
PSPA is an excellent cracking-resistant
toughening curing agent with low melting point, low toxicity,
moderate viscosity and good compatibility with a wide variety
of epoxy resin. The cured substances have good thermal-state
electrical property, mechanical property, especially, the
excellent resistance to cold and heat impact. It is widely
used in all kinds of household appliances, electromechanical,
electronic and national defence industry, etc.
2. Main Ingredient:
long carbon-chain aliphatic polycondensated
anhydride of dibasic acid
3. Technical Index:

4. Main Uses:
It is mainly used as cracking-resistant
toughening curing agent for insulating materials and cast
materials of epoxy resin in household appliances, electromechanical,
electronic and national defence industry, etc.
5. Packing, Storage and Transportation:
6kg/plastic bag, then place into the iron
tin and sealed. Stored in dry, ventilated, shady and cool
place. Keep away from rain and sunlight during transportation.
The storage period is one year.
