example

[0129] The invention is further explained below by means of illustrative, non-limiting examples.

[0130] Substances utilized in the examples include:

[0131]

[0132] The following test method was used to evaluate the removal of permanent marker writing.

[0133] Use SHARPIE on the test surface TM Write with black permanent marker. After 24 hours at room temperature, water was applied to the surface. The writing on the surface is then wiped with a damp paper towel. Continue scraping until the writing is removed, or there is no change in the amount of marking left on the board. Record whether writing is removed by wet wipes. For permanent markers that are difficult to remove with water alone, spray some WINDEX on the writing TM glass cleaner, then wipe with a paper towel to remove.

example 1

[0135] The outer coating of Example 1 was formed from a composition by adding 3-(N,N-dimethylaminopropyl)trimethoxysilane (49.7 g, 239 mmol) to a screw cap jar , then prepared by adding deionized (DI) water (82.2 g) and 1,4-butane sultone (32.6 g, 239 mmol). The combined reaction mixture was heated to 75°C and mixed for a period of 14 hours. The resulting reaction mixture was diluted with water to 2% by weight to obtain a final coating composition, which was then applied to the front surface of the body member.

[0136] In Example 2, the overcoat was formed from a composition prepared as 2% by weight of [LITHISIL TM 25 Lithium silicate: Example 1 preparation composition (23:77 w / w)] in aqueous solution.

[0137] 100% SHARPIE after 10 uses TM The black permanent marker remains easily removable. After seven uses, the marker lined the glossy sample, but the optically rough structured surface caused by rolling was not lined with the marker. Thus, durability is improved by mic...

Abstract

Cleanable articles having overcoats with hydrophilic front surfaces and which are siloxane-bonded to an underlying body member. Also, methods of making and using such articles.

Description

technical field [0001] The present invention relates to articles having cleanable surfaces, methods of making them, and methods of using them. Background technique [0002] Ease of cleaning of surfaces, such as removal of dust and dirt, graffiti, or erasable surfaces is a long desired feature. Exemplary applications where ease of cleaning is desired include windows, electronic device screens, countertop surfaces, appliances, door and wall surfaces, signage, and the like. Other exemplary applications include writable surfaces such as dry erase boards, folders, notebooks, etc., where efficient writing and subsequent easy removal of the writing is desired. [0003] Articles with writable cleanable surfaces are prepared from a variety of materials offering various combinations of properties. Commonly accepted examples include certain label materials, dry erase products, stationery, folders with cleanable labels, and the like. [0004] Due to their convenience and versatility,...
