Patent CA-2025430-A1 (CA)
Title: Coated abrasive containing a pressure-sensitive adhesive coatable from water
Inventor: BANGE DONNA W
IPC: C09J7/38
Filed: 1990-09-14
Abstract: This invention relates to coated abrasive products having a pressure-sensitive adhesive layer coatable from water.      Many coated abrasive products, especially coated abrasive sheets and discs, are mounted on a support pad, sometimes called a back-up pad, during use. One means for securing the coated abrasive article to the support pad calls for a pressure-sensitive adhesive. Typically, the surface of the coated abrasive article not containing the abrasive grains will bear a layer of pressure-sensitive adhesive.      For many years, pressure-sensitive adhesives have been coated fram organic solvent solutions onto the non-abrasive side of the coated abrasive article with excellent results. However, because recent governmental regulations require reductions in solvent emissions, the coated abrasive industry desires to eliminate all organic solvents from their coating operations. This invention provides a coated abrasive product having a backing bearing abrasive grains on one major surface thereof and a pressure-sensitive adhesive, coatable from water, on the other major surface thereof. The pressure-sensitive adhesive can be used to secure the coated abrasive to a support pad or back-up pad. The support pad provides the coated abrasive with the necessary foundation during abrading operations. The pressure-sensitive adhesives of this invention can adequately secure the coated abrasive to the support pad even at high rotation speeds and at high grinding pressures. Previously known pressure-sensitive adhesives for coated abrasives that are coatable from water were unable to provide this property.

Title: Alkylated oxo-piperazinyl-triazine
Inventor: SON PYONG N
IPC: C08K5/3492
Filed: 1991-03-18
Abstract: ABSTRACT OF THE DISCLOSURE       A stabilizer compound for synthetic resinous materials is a tri-substituted triazine in which each substituent is a N4-methylated 2-keto 1,4-diazacyclohexane connected to the triazine ring through an alkylene bridge. This bridge permits efficient methylation of the N4 atom in every substituent under conditions which yield crystals having at least 90% purity. These crystals may be further purified to at least 95% purity at which purity level they contain less than 500 ppm ash. The stabilization effect of 95% pure compound in a polyacetal is such that, even with an ash content of 50 ppm, it has better stabilization properties than its 99.2% pure precursor (the non-methylated tri-substituted triazine) with an ash content of 10 ppm, as evidenced by lower formaldehyde evolved and better color retention, that is, developing less color in a water white sample after testing at 259°C.
