It is the responsibility of the purchaser to download and read the information. Please think of the environment before deciding to print!, MIXING RATIO: 100:70 VCat Setting Time: 18-22 minutes Which translates as 100g plaster 70g water. Since 100cc or ml of water = 100g, one can assume 100g plaster to 70cc water. To approximate the requirement for the mould, fill the mould with water and empty into a mixing container, ideally graduated. Divide the total volume by 70 and multiply by one hundred for the correct weight of plaster. Sprinkle or seive the plaster into the water and allow to abosorb water fully before stirring Do not whisk, you will entrain air and cause bubbles! You can also estimate the amount of plaster needed by sprinkling plaster onto the measured water and continue to do so until the plaster level reaches the water level in the container. You will see a sub surface lunar landscape like picture. Our friends at hirstarts.com also have a pictorial mixing guide for this Heath Robinson method

All datasheets are available for download on the item where your purchase was made. It is the responsibility of the purchaser to download and read the information. Please think of the environment before deciding to print!, Polyester Gelcoat & Flowcoats are cured with MEKP, a corrosive peroxide. It is added at 0.75% to 4% by weight. We do not recommend under 1% as any error in weighing may mean the product fails to cure. Adding more MEKP will reduce the working time (POT or POTLIFE) and mean the resin reaches peak exotherm faster. It will not make the system exotherm any more than with a lower dose, it simply gets to its cross linking temperature faster. It is a myth that adding less MEKP affects the maxium exotherm temperature! Weigh out the desired volume of gel/flowcoat Calculate the required catalyst (1-4% by weight) Add the catalyst and stir well ensuring you combine the whole mix Stand briefly to degass If using degassing equipment bear in mind the vapour pressure of the product. Excess drawn vacuum will boil the product Pour and allow to cure
