More specifically, this invention: Glass, metal, rubber, concrete-like surfaces and plastics, non-porous or provides temporary protection when used on painted surfaces that have not been affected by solvents. Aqueous polymeric compositions for forming protective coatings, i.e. easily peelable coatings .

住居用および商業用を問わず新しい建造物の清掃は、新しい建造物用に業として 清掃サービスを提供している者にとっても、真に問題となることである。窓の清 掃をより容易にかつより速〈実施するためのものに対しては、かねてより希求が あった。多くの物質が試みられ、それにはクリスコ（Ｃｒｉｓｃｏ）およびピー ナツ油さえあったのであるが、しかしこれらについては次のような問題が認めら れる。すなわち、これらのあるものを除去することは、ガラスおよび（または） 金属表面に飛び散ったり、滴下したり、沈着したりした塗料、モルタル、織物、 その他を直接掻き取る場合よりも大きな問題である。この新しい物質は、液状で 提供されるので、表面保護の−ために噴霧塗装することができる。この材料は、 ガラス、金属、ゴム、コンクリート様の表面およびプラスチックの非多孔性ない し塗装表面で一般に溶媒の影響を受けていないもの、を一時的に被覆して保護膜 を形成する。すなわち、この保護膜は、施工中にそのうえに沈着した塗装、モル タル、泥、およびダストまたは他の異物と共に容易に剥ぎ取ることができるもの である。この一時的の保護被覆は、カミソリの刃やガラスを傷つけあるいはガラ スを破損させることのある研摩洗浄剤の使用を大きく低減させる。施工中に砂、 モルタルおよびセメントならびに他の異物をガラスに直接触れさせないことによ って、損傷ガラスを擦り傷のない非破損ガラスと取り替えあるいは（かつ）ガラ スを磨くという費用のかかるサービスが低減される。これによって、取替え費用 の低減ならびに多くの場合に清掃回数の低減もできて、大きな節約が得られる。Cleaning of new construction, both residential and commercial, is a professional practice for new construction. This is also a real problem for those providing cleaning services. Window cleanliness There has long been a desire for something to make cleaning easier and faster. there were. Many substances have been tried, including Crisco and Pea. There were even nut oils, but these had the following problems. It will be done. That is, removing some of these may result in glass and/or paint, mortar, textiles that have been spattered, dripped or deposited on metal surfaces; This is a bigger problem than directly scraping off other parts. This new substance is in liquid form. It can be spray coated for surface protection. This material is Non-porous on glass, metal, rubber, concrete-like surfaces and plastics A protective film is created by temporarily coating painted surfaces that are generally unaffected by solvents. form. In other words, this protective film protects against paint and moles deposited on it during construction. Can be easily stripped off along with tar, dirt, and dust or other foreign matter It is. This temporary protective coating will not scratch or damage razor blades or glass. greatly reduces the use of abrasive cleaning agents that can damage the sand during construction, Avoid direct contact of mortar and cement and other foreign objects with the glass. Therefore, replace the damaged glass with undamaged glass that has no scratches or/and The costly service of polishing the surface is reduced. This will reduce the replacement cost and in many cases also reduce the number of cleanings, resulting in significant savings.
