Abstract: Many family homes, school and municipal parks have play structures for children. Typically these playground play structures have ladders. In the case of family homes in particular, toddlers typically enjoy climbing the ladders but then are stuck at the top and in danger of falling off the ladder. In order to prevent toddlers from climbing the ladder of the play structures when unattended by an adult, and ultimately preventing injury, an invention that prevents the ladder from being climbed by a toddler is presented here.

Abstract: The present invention relates to methods of preparing a substrate for bonding that includes applying a cleanser to a reaction injection molded component. The substrate is dried to remove some or all of the liquid of the cleanser. The invention also relates to methods of bonding two substrates together. After cleaning the surface of one substrate with a basic solution, a primer may be applied to the cleaned surface or to a second substrate. An adhesive is then used to join the substrates together.

Abstract: The invention is a composition comprising: a) one or more film forming resins having at least one functional group capable of polymerization; b) one or more reactive diluents capable of reacting with the film forming resin; c) one or more silicon, titanium, zirconium, aluminum or metal containing compounds capable of promoting adhesion of the composition to glass; d) one or more fillers capable of imparting abrasion resistance to the composition when cured; and e) one or more compounds which is reactive with the film forming resin which also contains at least one acidic moiety. The composition of the invention is useful as a frit on the window of a vehicle. Furthermore, the invention relates to a method for applying the coatings to glass and a method for bonding the coated glass to a structure or substrate, for instance, a building.

Abstract: The invention is a composition comprising a) one or more organotitanates or zirconates having four ligands wherein the ligands are hydrocarbyl, optionally containing one or more functional groups having one or more heteroatoms selected from the group comprising oxygen, nitrogen, phosphorus and sulfur wherein two or more of the ligands may form a cyclic structure with the proviso that one of the ligands has an acidic moiety; one or more strong organic acids or a mixture thereof; b) one or more alkoxysilanes; c) optionally one or more high molecular weight resins; and d) a solvent which dissolves the components of the composition. This composition is referred to as a clear primer hereinafter. Preferably, the composition comprises both an organotitanate or zirconate and a strong acid.
