4,4’ Diamino Diphenyl Sulfone:
Dapsone is an aromatic curing agent for glycidyl ether resins which initiates resin homopolymerization at elevated temperature when used in following proportion:
| Resin | Part by Weight |
|---|---|
| Diglycidyl Ether Resin | 100 |
| Dapsone | 36 |
| BF3MEA (Accelerator) | 1 |
Our Dapsone-Tech is white crystalline powder exceedingly soluble in alcohol, acetone and MEK with a purity range of 99.5%. It has been established that purity of resins and hardener in epoxy system achieves highest Tg (glass transition temperature) and HDT( Heat Distortion Temperature) for high performance in aerospace applications. Our product with a purity of 99.5% offers the facility for achieving a high Tg and HDT.
According to the Army Materials and Mechanics Research Center at Watertown, MA, trace impurities have a significant effect on the reactivity of the resin and may adversely influence the reliability and performance of the composite material. Using our proprietary manufacturing process, we produce high quality Dapsone-Tech starting with excellent quality raw materials with low/no moisture and isomer contamination that in turn ensures extremely low isomeric impurities in the final product.
4,4’ Dichlorodiphenyl Sulfone:
DCDS is a specialized monomer used as a starting material for production of polyether sulfones, diaminodiphenyl sulfone and dihydroxydiphenyl sulfone.
High purity of the product coupled with very low contamination of isomers like 2,4’or 3,4’ makes DCDS an ideal intermediate. Our DCDS assures both.
