Resin catalyst chart

25 Mar 2016 Thorough mixing is important, and the ratio of catalyst to resin weight affects cure rate and, potentially, the degree of cure. For example, 1% is  To get a ratio of 3:1 one-third Cure It Roofing Resin (with hardener added) should be applied on the board and two thirds resin and hardener on the mat dip the 

catalyst concentration & equivalent measure chart Specific gravity MEK peroxide = 1.17 polyester resin= 1.09 gelcoat = 1.3 Equivalent Measures Chart Catalyst Chart for polyester resin, gel coat and vinyl ester marine resins. Methyl ethyl ketone peroxide (MEKP) is an organic peroxide used in the marine industry. This chart is intended as an approximate guide only, and is expressed in drops of catalyst per ounce of resin. It is based on a room temperature of 70°-75°F. For warmer temperatures, decrease catalyst by a drop per ounce of resin; for cooler temperatures, increase the amount of catalyst by a drop per ounce of resin. NCINSTGCCAT-v.2 REPAIR PROCEDURES Catalyst (MEPK) Ratios for Gelcoat and Resins Add the MEKP to the Gelcoat before thinning. ENCLOSED: • Dropper bottle that will yield the exact ratios referenced on this chart when mixing small NOTE: Using drops for catalyst measurement is only an estimate. In critical applications, MEKP should be measured using cc's or fluid oz's which are volume measurements. The percentages in the chart, 1% thru 2%, are percentages of resin or gelcoat by weight. MEKP Ratio Chart Polyester Resin Polyester resin cures by an exothermic (heat) reaction created by promoters (cobalt & amine) and activator Methyl Ethel Ketone Peroxide (MEKP). The reaction of polyester will occur at the thickest cross section sending out a wave of heat, which cures resin to a solid glass-like hardness.

The ratio range for catalyst to resin is 1 to 2 percent hardener to the total volume of resin to be used. For example, four drops of hardener will be 1 percent of 1

Click to  MEKP (Methyl Ethyl Ketone Peroxide) is the catalyst added to polyester resins and vinyl ester resins. As the catalyst mixes with the resin, a chemical reaction  21 Oct 2016 If the mix ratio is 10:1 that is 10 parts resin (A) to one part catalyst which is often called the hardener (B). Sounds simple enough – but is that ratio  So I was stuck buying resin from the local boatyard today for a quick the cooler the conditions, requires more catalyst, and whether you are

Each kit includes resin and clear MEK catalyst. Although the shelf life for this product should be at least six months, the shelf life will be greatly reduced if it is  The mix ratio for a two component epoxy is the correlation between the resin and catalyst, also known as the hardener or curing agent, required to realize a full  liquid.
