When it comes to building materials, quality matters. However, it is not always easy to achieve the desired performance level, especially on a consistent basis. This is where METHOCEL™ cellulose ethers come in handy. METHOCEL™ consists of hydroxypropyl methylcellulose (HPMC) cellulose ethers that can help you create industry-leading building materials with superior performance and greater durability. From cement mortars to concrete, METHOCEL™ cellulose ethers can help you make building materials that will withstand the test of time.
Cellulose ethers are a family of chemicals with properties similar to cellulose, the most abundant organic compound on Earth. METHOCEL™ HPMC is derived from wood pulp, biodegradable, and safe for the environment.
METHOCEL™ plays a critical role in producing cement-based building materials. As additives, these cellulose ethers provide superior performance, durability, and ease of use. They are ideal for use in building materials primarily because they provide the following benefits:
• Exceptional application performance in cement mortar and concrete mixes
• Enhanced durability and strength
Achieve Superior Performance with METHOCEL™ HPMC
Exceptional performance in cement mortar and concrete mixes: METHOCEL™ increases workability and enhances mixing characteristics by providing lubrication for dispersed particles in a mixture, leading to smooth, homogeneous finishes. It also increases consistency and improves rheology in mixes, further creating better workability through higher ease of spreading. METHOCEL™ also increases adhesion to walls and surfaces, preventing sagging in cement-based products like plasters.
Increase durability and strength: METHOCEL™ has extremely high water retention properties, which help slow evaporation and provide more hydration to the cement over a longer period, allowing better mechanical strength to develop. This also contributes to better homogeneity and reduces the risk of cracking. Products like plasters are often applied to porous and absorbent surfaces, leading to water loss in plasters and poor strength. The water retention properties of METHOCEL™ help mitigate this, retaining more water for the proper strength to develop. In addition, METHOCEL™ cellulose ethers improve the compressive strength of concrete by binding the particles of concrete mix together. These compounds formed from binding also make concrete less susceptible to pressure-related cracking. Additionally, cohesive strength may be improved through the interlocking that occurs with cement paste.
Summary
METHOCEL™ HPMC is the perfect choice for improving the quality and performance of your building materials. Adding METHOCEL™ to your cement mortar or concrete can make your building materials stronger, more durable, and resistant to cracking and other damage. These cellulose ethers are also valuable in gypsum-based products for many of the same reasons.
