Question

I have to add 5 volium percent of a catalyst in 1.6g of a resin. how much catalyst I have to add to resin?

Answer 1

If you don't have the means to measure the volume accurately, you might also be able to calculate it if the manufacturer provides the specific gravity (density) in their MSDS sheet. I have done this with polyurethane resins to convert between mix by volume ratio and mix by mass.

Volume = Mass / Density

Answer 2

You are going to have to determine the volume of 1.6 g of resin, most likely by measuring the volume.  

Place a small, empty, graduated volumetric container on a scale.  Balance the scale, then add 1.6g of resin and measure the volume on the graduated cylinder.  

The catalyst volume is 5% of that volume.

If you cannot retrieve the resin from the container, at least you know what volume of catalyst to use, for fresh resin out of the original package.
