20160159833 | HYDROXYMETHYL-CARBOXAMIDO-SUBSTITUTED SILANE AND ITS USE FOR CURABLE, SILANE-TERMINATED POLYMERS - Specific hydroxysilanes of formula (I), a method for the production thereof, the use thereof as a constituent of moisture-curing compositions, and silane-functional compounds produced therefrom, in particular silane-functional polymers and isocyanatosilanes. The hydrosilanes can be produced in a simple process with a high degree of purity and are storage-stable after production. Production from the reaction of lactides with aminosilanes is particularly advantageous. Hydroxysilane of formula (I), where n is 1 or 2. | 06-09-2016 |

20220135834 | TWO-PART HYDROPHOBIC POLYURETHANE FORMULATIONS FORMING CORROSION RESISTANT COATING - A two-part polymerizable formulation that upon mixing includes a saturated aliphatic polyester prepolymer present in an amount of between 10 to 65 weight percent of the total formulation having a viscosity of between 100 and 955 cP at 25° C. An organic solvent is present in an amount of between 25 to 55 weight percent of the total formulation. An additive of hexamethylene diisocyanate trimer, isophorone diisocyanate dimer or trimer, toluene diisocyanate or methylene diphenyl diisocyanate, or combinations thereof is present in an amount of 17 to 25 weight percent of the total formulation. A process of forming a polymerized coating on an article includes the application of the formulation to a substrate of the article. After allowing sufficient time and temperature for solvent to evaporate to accelerate a rate of cure of the polymerizable compound to form a polymerized coating on the article. | 05-05-2022 |
