For optimum results, StarPel™ 366-01 should be cured with StarTex™ CATALYST 605 at a ratio of three parts silicone emulsion to two parts catalyst. StarPel™ 366-01 is also recommended for use as a softener. It may be used alone or in conjunction with other softeners such as PERMAFIN 20 or StarLube™ 243 depending on the final properties desired. A level of 1–2% StarPel™ 366-01 is very effective with no catalyst being required for StarPel™ 366-01. In this case, no special catalyst for curing the silicone would be required. Normal pad/dry/cure techniques would suffice.

StarPel™ 366-01 may be used effectively on polyester/cotton rainwear to obtain durable results – with exceptional economy – using the following formula:

StarTex™ RESIN G-90W: 3%
StarPel™ 366-01: 3%
StarTex™ CATALYST 605: 2%
StarTex™ CATALYST CT: 0.5%


StarPel™ 366-01 should be stored in closed containers and protected from freezing.
