| Products Aqualon is a worldwide supplier of a broad range of cellulose ethers and functional additives. These products improve the performance of building materials in a variety of construction applications. Culminal® methylcellulose, methylhydroxyethylcellulose, methylhydroxypropylcellulose CULMINAL products help building materials apply more easily and perform better. They provide water retention and cohesiveness to mixtures. With special modification, our CULMINAL methylcellulose derivatives can be used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product. CULMINAL products are specialty products based on methylcellulose (MC) and its mixed ethers methylhydroxyethylcellulose (MHEC) and methylhydroxypropylcellulose (MHPC). Selecting the right chemistry depends on your application. CULMINAL products are soluble in cold water and stable over a wide pH range. The different grades are chemically and physically optimized for adjusting and controlling specific properties of dry mortars and building products. They are available in different molecular weights, particle sizes and modifications. For more information, go to CULMINAL Physical and Chemical Properties Natrosol® hydroxyethylcellulose, regular and biostable grades Our Natrosol product line consists of hydroxyethylcellulose products of differing molecular weights (viscosity levels) and particle sizes. Natrosol products are available as regular HEC and as HEC with increased biostability (Natrosol B). High viscosity Natrosol grades provide good thickening properties in aqueous systems. Low molecular weight Natrosol grades are often used as stabilizers in self-leveling compounds based on cement or gypsum. Our fine particle size materials, represented as X-grinds, such as Natrosol 250 HXR, are recommended whenever a quick dissolution is required. Natrosol CG 453 is a special product for latex based building materials such as tile adhesives and plasters and has the unique feature of combining very effective thickening with high sag resistance. For more information, go to NATROSOL Physical and Chemical Properties Nexton® specialty water-soluble polymers NEXTON specialty polymers are a family of non-ionic additives for the construction industry. Their unique chemistry provides desirable texture in cement, gypsum and latex-based products improving workability, cohesiveness and appearance of the building material with less influence on setting characteristics. As stand alone products or complements to Culminal or Natrosol cellulose ethers, their key function in a wide range of aqueous-based products is to manage the physical properties of water so that optimum rheology, stabilization and other wet, dry and cured properties are provided. NEXTON products have been developed specifically for masonry systems – (NEXTON D- and M- types), for tape joint compounds – (NEXTON J- and IP- types), gypsum plaster – (NEXTON DG-types) and for stuccos and renders – (NEXTON CS-types). These products vary in viscosity, particle size, solubility and modification. Some of these products offer multi-functional performance, enhancing not only workability, but also entraining air.
Silipon™ air entraining agents and wetting agents The Silipon range consists of various air-entraining agents. The main function of those products is to incorporate a predefined amount of homogeneously distributed air bubbles in building mortars. This reduces the density of the wet mortars and improves workability. As dry mortar producers’ requirements differ in terms of dissolution time, air content and size of air bubbles, Aqualon offers a wide range of air entraining agents to chose from. Silipur RE 2971 defoamer is very effective for dry mortars in which the air content should be as low as possible. This is especially valid for self leveling compounds based on cement or gypsum. The starch ether range, consisting of different Amylotex and ST products, provided by Aqualon is recommended to fine-tune the anti-sagging properties of dry mortars such as tile cements, plasters and renders and to increase the yield and the water demand of those systems. They lead to better workability and improved application properties of the wet mortar. Galactasol® derivatized and unmodified guar-based galactomannans The Galactasol line is a series of nonionic and anionic derivatives plus natural or unmodified guar gum that are very efficient viscosifiers and rheology agents for non-cementitious, water-based construction products. Galactasol solutions typically exhibit strong pseudoplastic behavior, excellent heat-stability, high salt tolerance, friction reduction and good cross-linkability. A typical application would include spray ceiling and wall textures. Galactasol products are available in a variety of molecular weights, particle sizes and special modifications to effect its solubility. Aqualon® sodium carboxymethylcellulose (CMC) Aqualon sodium carboxymethylcellulose and Blanose refined CMC are two designations for the sodium salt of carboxymethylcellulose produced either in Aqualon’s Alizay, France, or Hopewell, Virginia, facilities. Produced typically for industrial purposes to 98% minimum purity, CMC is anionic and acts as an effective thickener, rheology control agent, binder, stabilizer, film former and water retention aid. CMC’s rapid cold and hot water solubility and ability to exhibit thixotropic behavior allow it to provide desirable properties in building materials requiring some texture in the finished product. Aqualon CMC is offered in several viscosity grades and three degrees of substitution.
