DMA Promotor
For use in speeding up gel time only where a fast gel time is needed to avoid slumping but a longer curing time to avoid shrinkage.The DMA helps the catalyst to start the chemical reaction between the resin and styrene monomer and form a cured solid. After adding DMA always allow a minimum of 1/2 hr for resin to sit before adding catalyst.DMA is a highly toxic substance, particularly to blood, kidneys and liver, and it can be fatal if inhaled, swallowed or absorbed through the skin. Splashes can be readily absorbed through the skin and vapours can be absorbed into the blood stream. It can burn skin and eyes.
