STABILISED HDK SUSPENSIONS FOR REINFORCEMENT OF REACTIVE RESINS

摘要

Suspensions, containing at least 3 wt. % of particulate thickening agent, with an amount of at least 5 wt. % of a polymer, based on the pure particulate thickening agent without polymer, is bonded to said particulate thickening agent in the suspension, optionally at least one further polymer or several polymers are present free in the suspension, the relative viscosity ?/?_o, where ? and ?_o are measured at the same temperature and at 25 °C, is less than 100 and the relative viscosity ?/ ?_o changes by less than a factor of 10 after storage for at least one week at a temperature of 40 °C and contains liquid phases, which, based on the total liquid phase, comprises 0 - 80 wt. % of a solvent or low molecular weight cross-linkable components with a viscosity of less than 100 mPas at 25 °C and, based on the total liquid phase, comprise 10-100 wt. % of polymer components or a mixture of two or more physically or chemically cross-linkable polymers.
