Catalyst Chart for polyester resin, gel coat and vinyl ester marine resins. The table below gives the correct ratios of catalyst to resin and gelcoat by weight. Adding more of less of the catalyst agent will speed up or slow down the curing time for the resin. 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). For best pricing we recommend buying ... 4:1 Ratio Fast Epoxy Hardener Use this chart to purchase the 4:1 FAST Hardener by itself. Repairs aren’t the only use for fiberglass resin products. of MEKP to 1 gallon of polyester resin. If it is a little warmer, maybe use 6-7 mls. So, you have 10.8 kg of fibreglass matting, 10.8 x 2 = 21.6 kg of Resin minimum, say 25kg of resin to be safe. MEKP HARDENER; Polyester resin; Gel-Coat. 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. Therefore, … For polyester Gelcoats used in a moulding situation, we recommend from 2% to 2.5%catalyst. A rule of thumb for polyester laminating resin is between 1% and 2% i.e. h�b```�3���@��(��������p�'��&��w��6 �j��������2�".F�g@Z�E�F�2�3Hɰ-�Mz0�ш�������0n�����{���V_�4'��"�KYg8 i1��@��d s�"�

Cloth weight (Ounces) Cloth width (Inches) Cloth length (Linear yards) Expected fiberglass percentage (30:beginner 40:average 60:infusion etc. Our CLR epoxy resin with CLF Fast Hardener works in a 100:47 mix ratio by weight or a 2:1 volume ratio. amount of resin or gelcoa t hardener amount 1 ounce 10 drops 1 pint (16oz) 1/8 ounce 1 quart (32oz) 1/4 ounce var mydate=new Date() The curing agent part of the epoxy mix is the expensive part. When combined with 105 Resin in a five-part epoxy resin to one-part hardener ratio, the cured resin/206 Slow Hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and barrier coating properties. Do not mix resin and hardener in a temperature below 60 F. Mix a few "practice" batches to get a feel for the application of the resin and hardener to the fiberglass cloth. Eg: 100ml Resin : 20ml Hardener or 100gm Resin: 18gm Hardener 530B- 3 Parts (A) : 1 Part (B) by volume Eg: 100ml Resin : 33ml Hardener or 100gm Resin : 28.5gm Hardener With General Purpose Resin (but not Gelcoat), the rate of cure can be slowed down by halving above ratios giving you a 1% liquid catalyst percentage per weight of resin. Air Humidity During Processing. Mark the measurements in your bucket before mixing or by using 2 measuring cups to measure how much resin and hardener to use. 105 Epoxy Resin is the base material for the West System family of products, on which all of the West System compounds are built. The standard ratio is 1 oz. Resin to Hardener Ratio: Measure epoxy resin and hardener to a perfect 1:1 ratio by volume. So, you have 10.8 kg of fibreglass matting, 10.8 x 2 = 21.6 kg of Resin minimum, say 25kg of resin to be safe.

This is incredibly important if you wish to polish the finished fiberglass resin or to color it. Resin is calculated between 2 – 2.5: 1 Resin to Glass ratio. 1-772-464-0808 M easure accurately! At about 70 degrees F, use about 7-8 ml's of hardener to one litre of resin. Epoxy coatings can also be used to waterproof and seal bar tops, tabletops, plaques, and more! Enter the dimensions listed below for a rough estimate of how much resin you will need to wet out a given amount of Fiberglass cloth. The amount of resin needed to do this varies from one glassfibre material to another. The table below gives the correct ratios of catalyst to resin and gelcoat by weight. Check out our video tutorial below that details how to use our graduated cups. When purchasing polyester or vinyl ester resin, this weight can be matched to the resin container. �X�T�A�L)�ɴ�ukC�cl���K����W��cB�$N`:���ǻ4���qp�ΪK�� v"�(��p �b CyL��~V�O�4��&���>��j%�y^TGG��x4&�tά�-렴7����7�9�̪�`�M���ǃ�yq�� %ww�t��r��jF�9W�h|2I+�hhǣ��u���V���5塔<8]$7+�E^
