Product Description
HYGROSCOPE PW is a non-dusting, paraffinic oil-coated calcium oxide powder (85%). It delays reactivity and acts as a desiccant in rubber compounds cured pressurless, including Microwave, LCM, Hot Air, and Fluid Bed systems.
By absorbing moisture from rubber and fillers, HYGROSCOPE PW converts into calcium hydroxide, preventing blisters and porosity during curing. Its non-dusting nature makes it safe and easy to handle.
