PUR Thickener for Aqueous Systems, universal
GENERAL INFORMATION
NUVIS FX 1010 is a high efficiency polyurethane thickener for use in aqueous coatings. The product is supplied as a liquid and is convenient to handle and ready for immediate use.
APPLICATION AND PROPERTIES
NUVIS FX 1010 is applicable in many aqueous systems such as emulsions, dispersions and emulsion paints e.g., based on polyarcrylic-, polyvinyl-acetate homopolymers and most terpolymers. NUVIS FX 1010 is recommended for a wide range of paint formulations, from gloss to matt paints. NUVIS FX 1010 improves the rheological and levelling properties of aqueous paints by increasing the high shear viscosity and suppressing the low shear viscosity. This results in aqueous coatings with a solvent-based alkyd like rheology. Film-build, brushing characteristics and appearance are improved compared to conventionally thickened aqueous paints. NUVIS FX 1010 acts as a binding agent in the coating and is totally compatible with the standard binders used in emulsion paints. Paints made with NUVIS FX 1010 have a higher degree of water resistance and increased scrub resistance than those made with cellulosic thickeners. Higher gloss levels in gloss emulsion paints are obtained by using NUVIS FX 1010 as opposed to polyacrylates or cellulosic thickeners. Combining NUVIS FX 1010 with a suitable pigment dispersant such as NUOSPERSE FX 600 gives outstanding gloss performance. For other emulsion paints we recommend the combination of NUVIS FX 1010 and NUOSPERSE FX 504. NUVIS FX 1010 gives excellent resistance to bacterial degradation and improves the viscosity stability, thus allowing a possible reduction in the level of preservative used. FEATURE -> CONSEQUENCE Based on a polyether polyurethane -> provides longterm -> viscosity stability -> improves weathering -> less sensitive to hydrolysis -> decreased water sensitivity Increases mid and high shear viscosity -> more alkyd-like rheology -> higher film build and opacity -> Improved flow and levelling characteristics Non-plastic flow -> reduces roller spattering
DOSAGE
NUVIS FX 1010 may be added to the milling paste or during the let-down stage. Best results are obtained when using a part in the milling paste and a part during the let-down. The quantity of NUVIS FX 1010 to be used is strongly dependent on the desired rheology and the composition of the paint system. In most cases a concentration of 0.2 – 2.0% NUVIS FX 1010 is sufficient. However, it is recommended to determine the optimum dosage for each case individually. In some high PVC-formulations it may be useful to use NUVIS FX 1010 in combination with cellulosic thickeners. Dilution methods: A. Addition to the pigment grind: NUVIS FX 1010 as such can be incorporated together with the other liquid components of the mill-base. B. Addition during let-down or as post-additive: NUVIS FX 1010 should be diluted with a mixture of water/propyleneglycol or water alone. Suggested possible dilution of NUVIS FX 1010: 1. 6% NUVIS FX 1010 94% water 2. 10% NUVIS FX 1010 35% propyleneglycol 55% water 3. 25% NUVIS FX 1010 37.5% propyleneglycol 37.5% water To make a 1 ... 4% solution we recommend first to make a 4 ... 10% solution and than dilute till the lower concentration.
