Glass fiber structure designed to reinforce bonded abrasive articles

摘要

The invention relates to a structure based on glass fiber coated with a resin composition designed to reinforce bonded abrasive articles, the resin composition including the following constituents in the proportions indicated, expressed in percentage by weight of solid matter:
75 to 98% of a mixture of at least one novolac having a glass transition temperature lower than or equal to 60° C. and at least one novolac having a glass transition temperature above 60° C.,0.5 to 10% of at least one wax,0 to 3.5% of at least one plasticizing agent.

主权项

1. A resin composition, comprising the following, expressed in percentage by weight
25 to 55% of at least one first novolac having a glass transition temperature lower than or equal to 60° C., 10 to 30% of at least one second novolac having a glass transition temperature above 60° C., 0.5 to 6.5% of at least one wax, 0 to 2.5% of at least one plasticizing agent, 25 to 45% of at least one alcohol, 0 to 15% of water, wherein the resin composition does not comprise a crosslinking agent.
