In sulphur-cured EPDM formulations, CaO is commonly used as a humidity absorber — but it can also consume accelerators, leading to reduced cure efficiency and increased compression set. Deostab N is specifically designed to prevent this interaction.
Key advantages:
• Prevents accelerator adsorption on CaO – ensures full availability of the cure system when introducing CaO / enables reduction of accelerators in existing systems
• More consistent cure behaviour – improved crosslinking efficiency and reproducibility
• 76 % plant content – reduced carbon footprint + renewable raw materials
with Deostab N, formulators can achieve a better balance between moisture management and reliable vulcanization.
Let’s explore your application together.
