low w/c values promote autogenous shrinkage. Wetting and dispersing additives unite both mechanisms of action in one product, i.e. air humidity) and their length is determined in periodical intervals. It results from capillary forces arising from the withdrawal of water from the fresh mortar. By using a shrinkage reducing agent both effects are reduced significantly. Based on active dispersant on pigment: Titanium dioxide: 1 - 3 %. They help us to recognize the ways our visitors use the website, and to identify website elements to further improve. The reason for this is e.g. The ADDITOL portfolio of Dispersants and Wetting Agents contribute enhanced appearance properties as they provide paint with higher pigment loading with improved gloss potential. Wetting and dispersing additive for mineral fillers in unsaturated resin systems and adhesives. Excellent jetness black and high transparency for HPP pigments. Powder defoamers should provide freeflowing properties and a low tendency to form lumps during storage. If all particles are charged identical, electrostatic repulsion takes place. ACAT distributes a number of dispersing agents from Mnzing Chemie. To do so three standardized specimens are produced in a special casting mould. In addition, Tensol DDM is compatible with commercially available acrylic, styrene-acrylic and vinyl acetate homo and copolymers. Saves the visitors preferences selected in the Cookie Box of Borlabs Cookie. Prepare the dye-bath using the above dye solution keeping material to liquor ratio 1: 50 and add 2 gm/liter leveling agent to this dye-bath. After 48 hours the specimens are removed from the mould und the length is measured (see Figure 1). . High performance dispersant for non aqueous organic pigments and carbon black. To check the influence of the defoamer on the properties of the selfleveling compound different parameters are measured. It has been developed to disperse organic pigments, carbon blacks and inorganic pigments for universal use in both, water and solvent based systems, including high solids. Therefore the hydration process is decelerated. This website uses cookies.

Product Shelf Life (month): 36 (in the unopened original packaging stored under conditions specified in the product documentation) You can use, for example, gloss and haze values of the coatings and the E of the rub-up test as test criteria. In machine mixed mortars the mixing time is reduced and therefore higher delivery rates can be achieved. This specific structure self-orientates the additive at the surface, reducing the surface tension of the liquid paint, the polar parts stay in the aqueous phase when the non-polar parts orientates at the interface. Personal data may be processed (e.g. wetting and dispersing additive for filled unsaturated polyester. The exact dosage should be experimentally determined through a ladder study. Shrinkage reducing agents contain surface active components to reduce the surface tension of water in capillary pores. Accept only essential cookies. View Details.

Our wetting and dispersing agents include both anionic and non-ionic types, and can be used in coatings and other applications to improve wetting of surfaces and dispersion of pigments and other particulate materials in both aqueous and non-aqueous media. Another measurement method is the so-called bubble. It is ideal for the manufacturing of coatings as well as for the manufacturing of resin free pigment concentrates. Especially suitable for water based applications. It may be either an electrostatic stabilisation, where the charge of the dispersing agent plays an, essential part, or a steric stabilisation, where the, chemical construction and the molecular weight of, the dispersing agent are the key factors. In the case of autogenous shrinkage this process is caused by a physicochemical process (hydration) and not by a simple evaporation to the ambience. IP addresses), for example for personalized ads and content or ad and content measurement. You can revoke or adjust your selection at any time under Settings.

Functions of Dispersing Agents: It assists in the process of particle size reduction of dye. For this reasons the process of autogenous shrinkage depends on the w/c value. Our field staff will be happy to advise you on the optimum selection of product and to support you in your laboratory work. This pressure deforms the gel particle and the pore structure is enlarged. It has been developed to disperse inorganic pigments for universal use in both, water and solvent based systems, including high-solids. Dispersing agents prevent particles flocculating by various mechanisms (electrostatic effects, steric effects). The black joint filler is blended with 0.5% of powder dispersant. On one hand hardly soluble calcium hydroxide, which is generated by hydration of the cement, is complexed by the active ingredients of the shrinkage reducing agent and kept in solution.

Some of the most important products are presented, The dispersing process consists of three stages. One can distinguish two different mechanisms of action: electrostatic and steric stabilization. The substrate wetting agent is used to improve the surface tension and permeability of the coating, so that it can better wet the substrate, thereby impr . This can for example be achieved by a volume expansion in the early phase of the hydration by adding sulphate (gypsum)[3, 4] or formation of hydrogen cavities (addition of aluminum powder).

High performance dispersant for 2K refinish systems - for organic pigments and carbon black. On one hand as chemically bound water of crystallization in the calcium silicate hydrates, and on the other hand adsorbed to the gel particles or, Shrinkage reduction in a self-levelingcompoundby using a shrinkage reducing agent (SRA). Powder dispersants increase colour strength in pigmented systems, reduce floating of pigments to the surface and attain a homogeneous surface (see Figure 7). It is based on the fact that the volume of the cement gel (hydrate phase) is smaller than the combined volume of mixing water and cement. ADDITOL XW 6575 on the other hand is a special grinding resin for Automotive OEM basecoat systems. Surface tension has to be lower than the, surface energy of the substrate. Table 2: Defoaming properties in a self-leveling compound, Figure 6: Optical impairment due to wrong defoamer selection. The specimens are stored for three months under standardized conditions (23C an 50% rel. Our supplier Mnzing Chemie and Applied Chemicals feel the responsibility of contributing towards environmental protection and sustainable development. BYK's wetting and dispersing additives result in a fine and homogeneous distribution of solid particles in liquid media and ensure the long-term stability of such systems. This leads to a higher stability of the mortar. Thezinc stearate that is usually used as a mold release agent is completely replaced by the additive, which can simplify raw material handling. Sometimes interactions between defoamers and plasticizers could be observed which also lead to an inhomogeneous visual appearance. isawettinganddispersingadditiveforamineacceleratedUP,EPand,PURsystemsand adhesives to reduce the viscosity in mineralfilled systems.
