    Abstract: Generally speaking, in accordance with the invention, a putty is provided that can include many or all of the handling characteristics of a traditional plumber's putty, but with reduced staining qualities. Such putty can facilitate substantially stain free installations. Putties in accordance with the invention can contain combinations of polymers or oligomers, solvents, fillers and optional rubbery materials. A composition according to the invention is preferably sufficiently stain-free to be used on porous stone, such as marble and granite, without damaging the appearance of the stone. This is achieved by eliminating oil completely, or at least substantially, or restricting their ability to cause stains sufficiently. Because compositions of the invention can be made to be free of oils, they can also have the effect of eliminating the greasy feeling to the hands, which can occur when handling traditional putty. Putties in accordance with preferred embodiments of the invention can provide a degree of tackiness for adhesion and gap fill purposes during installation, as well as a degree of abrasiveness so that pressure from the tightening process will not cause the putty to slip. Of these benefits, one particularly important advantage is the lack of staining on most, if not all, surfaces traditionally used to finish kitchens and baths, including porous stones and other porous materials, such as unglazed ceramics.

    Abstract translation: 一般而言，根据本发明，提供了可以包括传统水管工腻子的许多或全部处理特性但具有降低的染色质量的油灰。 这种油灰可以促进基本上无污染的装置。 根据本发明的油灰可以包含聚合物或低聚物，溶剂，填料和任选的橡胶材料的组合。 根据本发明的组合物优选是足够无污染的，以用于多孔石材如大理石和花岗岩，而不损害石材的外观。 这是通过完全消除油脂，或至少基本上消除油脂，或限制其足够引起污渍的能力来实现的。 由于本发明的组合物可以不含油，所以它们还具有消除在处理传统油灰时可能发生的对手的油腻感的作用。 根据本发明的优选实施例的油灰可以在安装期间提供粘合和间隙填充目的的一定程度的粘性，以及一定程度的磨损程度，使得来自紧固过程的压力不会导致油灰滑动。 在这些优点中，一个特别重要的优点是传统上用于完成厨房和浴缸的大多数（如果不是全部）表面缺乏染色，包括多孔石头和其它多孔材料，例如无釉陶瓷。

    Abstract: A sealant is provided that possesses many or all of the characteristics of conventional thread sealants, and allows application with improved smoothness and uniformity of application. Sealants in accordance with the invention utilize engineered fibers such as melamines like Basofill and polyaramids such as Kevlar in its composition. Engineered fibers offer consistency and uniformity that other previously used sealants lack. Engineered fibers can improve the gap filling characteristics of the sealant, as well as the resistance of the sealant to chemicals and high pressures. Engineered fibers tend to have very high strength and low density.
