METHOCEL™ can be used in a wide range of building materials, including gypsum-based building products, finish materials, and caulking materials. It is derived from wood pulp, biodegradable, and safe for the environment, and it has excellent adhesion properties. With their versatility and reliability, METHOCEL™ cellulose ethers are the perfect cost-effective solution for improving performance in all your gypsum building materials.
METHOCEL™: The Binding and Water-Retaining Agent for Gypsum Products

As a powerful water-retaining and binding agent, METHOCEL™ cellulose ethers help achieve full hydration of gypsum, which is essential to providing excellent performance to gypsum products. In the case of gypsum plasters, for example, it ensures good adhesion, guarantees flat and smooth walls, and prevents cracking. METHOCEL™ can increase fire resistance and thermal insulation and reduce indoor humidity when added to gypsum products.

Optimize Gypsum Product Performance with METHOCEL™

Improve adhesion and ensure adequate hydration: Cellulose ethers like METHOCEL™ can improve adhesion and ensure adequate hydration of gypsum-based concrete mixtures. This helps ensure water does not quickly evaporate away, exposing walls and other surfaces to a higher risk of cracking.

Increase strength and durability: The water retention properties of METHOCEL™ allow concrete to fully hydrate even over long periods, resulting in higher mechanical strength. METHOCEL™ also helps create a bond between the cement and aggregates in the mixture, which is essential for providing adequate strength. Thus, METHOCEL™ cellulose ethers increase the strength and durability of gypsum concrete.

Enhance moisture resistance and reduce cracking: METHOCEL™ cellulose ethers can help prevent moisture migration, keeping the concrete from cracking when exposed to water. Since METHOCEL™ helps form more homogeneous surfaces with products like plaster, METHOCEL™ can also help minimize cracking in concrete. This is especially useful when working with a mixture with high water-to-cement ratios. Fibers or special fillers may also be added to a mixture containing METHOCEL™ before pouring to further reduce the risk of cracking.
Create smoother surfaces: METHOCEL™ helps to disperse particles within mixes more evenly, avoiding lump formations and lending to smoother, more visually appealing surfaces.

Obtain higher workability: METHOCEL™ cellulose ethers can increase the workability of gypsum-based mixtures, making products like concrete easier to pour.

Reduce cost: METHOCEL™ cellulose ethers can reduce the overall cost of projects by reducing the amount of cement needed for each batch.

Reduce permeability: METHOCEL™ cellulose ethers can reduce permeability in concrete and other building materials, helping prevent water from flowing through too quickly.

With METHOCEL™ cellulose ethers, you can ensure durable, smooth, and visually appealing finishes that will last. It is an ideal solution for both interior and exterior applications, including plastering and rendering.
