abron pa936 resin system consists of three parts, resin, hardener and solvent. The hardener ( part b ) is to be dissolved into the solvent ( part c ) and then the resin ( part a ) is added to form the resin solution ( specificratios to be taken ). 

the main application of abron pa936 system is to manufacture epoxy diamond dotted paper used in the manufacture of electrical transformers. On application to the electrical grade craft paper ( applicator machine ) the resin becomes tack free and remains so for a period of six months in bstage. 

on heating the paper to 90⁰c, the resin melts and cures completely in 90 minutes. When used in transformer windings the epoxy holds the coils in place thereby increasing the life of the transformer.

For every 100 parts by weight of the resin 6 – 8 parts by weight of the hardener is to be added. Stir / Mix well for about 3-5 minutes. Apply the mixture within 30

minutes. By varying the amount of the catalyst in the resin, the pot life and cure speed can be achieved. Higher the catalyst the shorter will be the pot life and higher cure speed. The composite is to be cured at 60 – 70°C. Post curing of the composite at 80 – 100 C is recommended to obtain optimum thermal and mechanical properties. Slow heating rate to cure the composite is suggested to avoid blisters and optimum cure.
