THYOSIL PU1052
Rheology Modifier 流变改性剂

Description描述

THYOSIL PU1052 is a hydrophobically modified polyethylene oxide urethane (HEUR) designed for interior and exterior paints ranging from highly structured to paints that portray nearly Newtonian behavior. THYOSIL PU1052 shows a very good balance of low and high shear viscosity. The nature of this balance is dependent on formulations and latex types. This allows the formulation of paints meeting a variety of rheological requirements, combined with excellent water and alkali resistance.

THYOSIL PU1052 can be used as a co-thickener in many types of formulations for attaining a desired balance of low and high shear viscosities,

是一款疏水改性聚氨酯（HEUR）流变改性剂,设计用于内外墙涂料和油漆，提高接近牛顿力学的流动性。显示了低和高剪切粘度的非常好的平衡。这种平衡的性质取决于配方和胶乳类型。这允许油漆的配方满足各种流变学要求，并结合优异的耐水和耐碱性。可以用作多种类型的配方中的共增稠剂，以获得所需的低和高剪切粘度的平衡。

Formulations Guidelines配方指引

• Incorporation 掺入

THYOSIL PU1052 is supplied as a pourable and pumpable liquid and should not need dilution. It can be added to the grind or during letdown. Addition to the grind, prior to dispersing, can accelerate the rate of viscosity equilibration.

The viscosity of THYOSIL PU1052 increases at lower temperatures. Therefore, if the product has been stored at low temperature, it should be allowed to equilibrate to room temperature before use in order to facilitate handling.

作为可倾倒和可泵送的液体，不需要稀释。它可以添加到研磨或配漆。在研磨分散之前加入可以加速粘度平衡速率。THYOSIL PU1052的粘度在较低的温度下会升高。因此，如果产品已经在低温下储存，则应在使用前将其平衡至室温，以便于应用。

• Rheology profile流变资料

High Shear: THYOSIL PU1052 is moderately efficient in raising the high shear (brushing) viscosity. Viscosity in this region is not very dependent on thickener interactions and is mainly a function of the amount of THYOSIL PU1052 present.

Should a higher ICI viscosity be desired, then a blend with THYOSIL PU1020 is recommended. ICI viscosity is not greatly affected by surfactants or water miscible solvents, since these have their primary effect on thickener interactions which influence the Stormer and lower viscosity regions.

高剪切：THYOSIL PU1052在提高高剪切（刷洗）粘度方面适度有效。该区域的粘度不依赖于增稠剂的相互作用，主要是THYOSIL PU1052存在的量的函数。如果需要更高的ICI粘度，则建议使用与THYOSIL PU1002混合使用。 ICI粘度不受表面活性剂或水混溶性溶剂的大的影响，因为它们对影响高和较低粘度区域的增稠剂相互作用具有主要影响。

Low Shear: THYOSIL PU1052 efficiently increases low shear viscosity, and the ratio of low shear to high shear viscosity will vary depending on the choice of binder and other formulation components.

低剪切力：THYOSIL PU1052有效地提高了低剪切粘度，低剪切粘度与高剪切粘度的比值将根据粘合剂和其他配方组分的选择而变化。

• Surfactants, Wetting Agents and Cosolvents表面活性剂，润湿剂和助溶剂

Excessive amounts of surfactants, wetting agents or cosolvents can slow down the viscosity equilibration by competing with rheology modifier hydrophobes for association sites, or in the case of cosolvents interfering with micelle formation.  However, these mechanisms can be manipulated in order to adjust the rheological profile of a paint formulation.

If the high shear viscosity is acceptable, but the Stormer viscosity is too high, it is not necessary to change the level of THYOSIL PU1052. The thickener interactions which contribute to the low shear viscosity can be reduced through the use of water miscible cosolvents or surfactants.

过量的表面活性剂，润湿剂或助溶剂可以通过与流变学改性剂疏水物竞争缔合位点，或在助溶剂干扰胶束形成的情况下，减缓粘度平衡。然而，可以调整油漆配方的控制其流变特性。如果高剪切粘度是可接受的，但是强粘度太高，那就不需要更换THYOSIL PU1052 有助于低剪切粘度的增稠剂相互作用可以通过使用水混溶性共溶剂或表面活性剂来降低。
