1 sylosiv Molecular Sieve Powderin metallic and Zinc-rich PaintsSince sylosiv powder adsorbs about 20 wt% ofwater, the amount of molecular sieve needed is easyto calculate. The water content of the raw materials canvary considerably from batch to batch; therefore, it issafer to work with an excess of sylosiv molecularsieve required proportions of sylosiv powder should bechecked through trials. The average amount of sylosiv powder required in the formulation is typically wt%. If assistance is needed, please contactour Technical Sales/Service of sylosiv PowderIncorporation of micronized sylosiv powders presentno problem when they are dispersed together with theother components of the paint by means of a fact that sylosiv zeolite grades in powder formadsorb moisture from the air spontaneously calls forspecial care in the handling of the powders.
2 The latterhave to be stored in hermetically sealed containers andonce opened should be used as quickly as Right Products for YouSYLOSIV powders with pore sizes of 3 or 4 should beused for this application. This pore size allows water tobe adsorbed, but larger organic molecules which oftenfunction as ingredients in paint formulations are too largeto be A4, sylosiv K300 and sylosiv A3molecular sieve grades are especially recommendedfor this application. Although Grace is not aware of anynegative interaction with other paint ingredients, thecompatibility of the alkaline zeolite powder in the customer spaint formulation should be tested in application contact our Technical Sales/Service support foradvice in selecting the most suitable material for yourapplication.
3 Special Product Information Sheets for eachgrade are available on DavisonMaterials & Packaging TechnologiesTechnical InformationFunction of sylosiv PowderIn certain paint and coating systems, moisture introducedinto the formulation via the raw materials (solvents, pigments,extenders) causes undesirable side metallic and zinc-rich paints (such as marine paints fortank ships and yachts), water reacts with the very activemetallic pigments such as zinc or aluminium, forminghydrogen. This leads to overpressure in the cans, andin extreme cases to + 2 H20 Zn (OH)2+ H22 Al + 6 H20 2 AI (OH)3+ 3H2 This effect can be avoided by the use of sylosiv molecular sieve. It adsorbs the moisture rapidly, with theresult that the above reactions can be supressed, thusreducing returns and storage to Determine the RightQuantity of sylosiv PowderSYLOSIV is employed for removing traces of water inmetallic and zinc-rich paints.
4 The content of water in thepigments naturally fluctuates from batch to batch. Toascertain a sufficient amount of sylosiv powder, thewater content of the pigments needs to be Davison has successfully pre-registered all REACH relevant substances. The nextstep is the ongoing preparation of the required registration dossiers andfinal registrationof our substances.
