Cleaning solvents such as Acetone and Isopropyl Alcohol. <> Now mix the amount of Cerakoke in the calculator with the amount of Catalyst next to it. You will need to do two calculations: one for the outer dimensions, then one for the inner dimensions. 1% for summer (to give maximum wetting time) and 2% for winter. The reason for this is that if the gelcoat is under cured, the backup laminating resin will bite into the gelcoat and cause wrinkling or puckering. unless otherwise specified. The volume calculator above will tell you how many units of resin and hardener you’ll need based on total volume. 1% is considered a slow mix, 2% is ideal, 3% is a fast mix. The resin’s reaction starts with the addition of MEKP at 0.5% to 1.5 % (2 % for thin laminates). H-Series coatings are a two-component, easy-to-apply, oven cure system that are VOC exempt in all 50 States. Have everything ready before starting work: cut glass mat to size. A Catalyst dispenser is ideally required for accurate measuring. Flex Roofing Resin & Catalyst Flexible Resin to withstand thermal expansion / contraction variations, slight movement in roof flexing and settling. For example, four drops of hardener will be 1 percent of 1 ounce of resin. An MEKP catalyst is mixed with polyester/vinyl ester resin in a very low ratio–just a few drops of catalyst per ounce of resin. Casting resins are used for making impact tooling or fixtures and are also used for encapsulating and potting applications. All of their retail formulas are two-part epoxy systems made up of a resin (Part A) and a hardener (Part B). Use as a guide as the temperature will vary on the catalyst ratio. xœí]é“G‘ÛòÁ@øÀ`-,°v—}ð4]w5ߌˆ%YK¬÷ƒ,K²aFÖiÿýfVuUfug÷¼iH¡PFuäñË£ªú=ÜôÒ›ÿâöñÁÏo„ͽÇpiˆCpp/öÖÇHč߬Ý}tïàáAìþImrúöñæ—7¡‹a3tÆk»¹yچØé¾Ú(ÕwNo‚r]ÜÜ<>øßí¯v‡}‚Ò.n?Ú)Ýõ¡wۛ»ÐYµÛþ÷îÐvN…¨¶¿Ûª.

Epoxy Putties are used for a variety of fabrication or sculpting applications and are available as rigid or semi-rigid. In this tutorial, we will show you two recommended techniques for measuring and mixing epoxy resins by weight or volume. 2) Always use a minimum of 1% catalyst even in summer to ensure a thorough cure. Sulfur-free clays for modelling and moulding applications. The miniumum ratio of catalyst is 1% and a maximum of 3% per weight of the product. Cures to a dull matte finish. unless otherwise specified. Only catalyze as much resin as can be used within the pot life. 4) Never underestimate the effect of temperature. so after regeneration we got hardness only 20 ppm but … The reason for this is Example 2: A resin system contains fillers which are Or with a single cup weigh out the larger of the ratio, normally the resin, and then top up with the hardner to your desired weight and then mix. As with all epoxy resins, our systems are designed to work in a specific mix ratio between the two parts. Generally speaking, for Polyester Resins, the mixing ratio is 2% i.e. 1-772-464-0808 After you've prepped your work surface and determined how much ArtResin you need, simply pour precisely equal amounts by volume of resin and hardener into a plastic mixing cup with well marked measurement lines. Plasters used for architectural castings, small craft castings etc. The standard addition rate is 2% (=20gm catalyst per kg of resin). It's also affected by temperature, humidity, etc. Use 0.07 inches for the depth if using inches or 0.16 if using centimeters. Just enter the lenght and width and you'll get the right amount of resin. Applications using sprayable materials and equipment.
