example

[0036] Sodium metaphosphate, potassium triphosphate, sodium hexametaphosphate, sodium polyphosphate, and calcium glycerophosphate were obtained from VWR International (West Chester, PA). Sodium tripolyphosphate, D-glucose-1-phosphate disodium salt hydrate, and D-glucose-1-phosphate dipotassium salt hydrate were obtained from Sigma Aldrich (Milwaukee, WI). Magnesium glycerophosphate and manganese glycerophosphate were obtained from Spectrum Chemicals (Gardena, CA). Scotchcast 4 is an epoxy resin system available from 3M Company (Saint Paul, MN).

[0037] The flame retardant fillers of Examples 1-10 were first mixed into Part B of Scotchcast 4 resin using a SPEEDMIXER DAC 150FVZ from Flack Tek Inc. (Landrum, S.C.) at 3000 rpm for 1 minute, and then also using a SPEEDMIXER DAC 150FVZ to Component A of Scotchcast 4 resin was mixed in at 3000 rpm for 1 minute. The total weight % of the flame retardant in the mixed resin was 15%. The weight ratio of component A / component B was 1....

Abstract

This disclosure relates to flame retardants that are useful for epoxy resin systems. Coating compositions and methods are provided that include an epoxy resin and a phosphate-containing flame retardant wherein the phosphate-containing flame retardant is selected from Group 1 metallic salts of a phosphate of a saccharide, Group 2 salts of a glycerophosphate, and Group 1 metallic salts of a polyphosphate. The provided flame retardants have low toxicity and are friendly to the environment.

Description

technical field [0001] The present invention relates to flame retardants useful in epoxy resin systems. Background technique [0002] Resins are used in many industries and for many different purposes. Resins are widely used, for example, in the electrical and electronics industries as seals for joints and other equipment, among other applications. Resins used in such electrical and electronic applications are generally required to have a set of acceptable electrical properties, some degree of flame resistance or flame retardancy, and acceptable levels of processability. In order to meet increasingly sensitive environmental and safety concerns, there is an ongoing need to provide substantially halogenated compounds and materials, and resin compositions free of halogenated compounds and materials. Currently available resins do not provide a range of desirable electrical, performance, processing and flame resistance characteristics without halogenated or halogen-containing c...
