The kit ships with one 20 kg pail of translucent KE1310ST base and twenty 100 g bottles of CAT1310 catalyst, enough to run a full mix series without ordering catalyst separately. Cured rubber comes in at Shore A 40 with 380 percent elongation, low shrinkage, and clean release from detailed patterns.\u003c\/p\u003e\n\n\u003ch2\u003eSilicone Mold Kit Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-component, addition-cure silicone mold kit\u003c\/li\u003e\n\u003cli\u003eIncludes 20 kg base pail and twenty 100 g catalyst bottles\u003c\/li\u003e\n\u003cli\u003e100:10 mix ratio by weight, base to CAT1310 catalyst\u003c\/li\u003e\n\u003cli\u003eShore A 40 hardness with 380 percent elongation\u003c\/li\u003e\n\u003cli\u003e5.9 MPa tensile strength and 23 kN\/m tear strength\u003c\/li\u003e\n\u003cli\u003eTranslucent for easy visual inspection of the cured mold\u003c\/li\u003e\n\u003cli\u003eAbout 2 hours working time at room temperature\u003c\/li\u003e\n\u003cli\u003eUsable temperature range from -40 F to 347 F (-40 C to 175 C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePopular Uses\u003c\/h2\u003e\n\u003cp\u003ePeople reach for this kit when a mold needs to hold fine detail through many casting cycles without going brittle. It is popular for molds that flex around undercuts while still giving a fabricator enough dimensional support to keep repeat pours consistent.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduction mold making for epoxy and urethane resin casting\u003c\/li\u003e\n\u003cli\u003eMolds with undercuts or complex geometry that need flex on release\u003c\/li\u003e\n\u003cli\u003ePrototype and pattern reproduction\u003c\/li\u003e\n\u003cli\u003eArt and prop casting where detail retention matters\u003c\/li\u003e\n\u003cli\u003eSelected potting work that calls for a firm, flexible silicone body\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSilicone Mold Kit Mixing and Cure\u003c\/h2\u003e\n\u003cp\u003eCombine 100 parts KE1310ST base with 10 parts CAT1310 catalyst by weight. Mix thoroughly, scraping the sides and bottom of the container until the color and texture are uniform. Vacuum degassing is recommended when the mold geometry or surface finish calls for minimal trapped air. Pour steadily into a properly prepared mold box and allow about 24 hours at 23 C to cure.\u003c\/p\u003e\n\u003cp\u003eWorking time runs about 2 hours at room temperature. Addition-cure silicones can be inhibited by sulfur compounds, amines, tin-cured silicones, and other catalyst contaminants, so run a small compatibility test when the master, release agent, or tooling material is unfamiliar.\u003c\/p\u003e\n\n\u003ch2\u003ePhysical Properties\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCure chemistry: Addition cure, two-component\u003c\/li\u003e\n\u003cli\u003eColor: Translucent\u003c\/li\u003e\n\u003cli\u003eMix ratio by weight: 100:10\u003c\/li\u003e\n\u003cli\u003eBase viscosity: 75 Pa s (75,000 cP)\u003c\/li\u003e\n\u003cli\u003eDensity at 23 C: 1.07 g\/cm3\u003c\/li\u003e\n\u003cli\u003eShore A hardness: 40\u003c\/li\u003e\n\u003cli\u003eTensile strength: 5.9 MPa\u003c\/li\u003e\n\u003cli\u003eTear strength: 23 kN\/m\u003c\/li\u003e\n\u003cli\u003eElongation: 380 percent\u003c\/li\u003e\n\u003cli\u003eUsable temperature range: -40 F to 347 F (-40 C to 175 C)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSurface Compatibility\u003c\/h2\u003e\n\u003cp\u003eKE1310ST is poured against a master pattern rather than bonded as an adhesive.
