Culminal™ methylcellulose (MC) derivatives help building materials apply more easily and perform better. Culminal products provide water retention, workability and cohesiveness to mixtures. They are also used to control thickening, water demand, open time, sag resistance, strength and other important properties of the final product.

Culminal methylcellulose derivatives include MHEC and MHPC chemistries, mostly as formulated solutions and tailored towards use in specific end products aiming to meet well defined end product property profiles and help achieving and exceeding national and international standards.

Culminal products are also available with retarded hydration to allow use in ready-to-use building materials. Culminal methylcellulose derivatives have applications in cementitious adhesives, gypsum plasters and fillers, joint compounds, renders and skim coats, self-leveling underlayments and floor screeds, and many more.

Ashland offers specific product lines of formulated solutions to address specific needs :

  • Culminal ™ UP - special products for lowest possible impact on cement hydration (faster setting)
  • Culminal™ Plus - for improved open time in cementitious adhesives
  • Culminal™ C and M series – universal products
