- Mix Ratio
- The gel time and cure time are both dependent on three parameters
- The percentage of MEK-P catalyst used
- The temperatures of all ingredients and the surrounding environment
- The mass concentration of the resin, a solid-cast shape vs. thin film. A good starting point, at 72°F, is 1-1/4 % catalyst by weight. This is equivalent to 10 drops catalyst per ounce of resin, or 1 teaspoon catalyst per pint of resin. This level will result in a 15 min pot life and a 24-hour cure. As temperatures rise above 72°F, decrease catalyst, and vice-versa. Polyester resins will not cure below 60°F. Experiment until the correct ratio is determined for your specific application. In general, mix what you can use in 10 minutes. Remember to always wear eye-protection when working with polyester resin and catalyst.
- The strength of a fiberglass composite comes from the glass fibers. Thus, in making a strong fiberglass part it is crucial to use the correct amount of resin. Using a fiberglass roller will help saturate all the fabric with a minimum amount of resin.
