Abstract
Abstract The invention relates to a binder composition comprising a low molecular weight resole resin in combination with boron compounds wherein said boron compounds are present in from about 1 to 30 parts per 100 parts by resole resin solids, said composition having a pH of about 2-6 and said resole having a viscosity of from about 5 to 5000 cps. Said binder provides laminates having superior electrical and flame retardant properties.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
A laminate comprising, a substrate sheet structure of fibers selected from the group consisting of cellulosic, asbestos, glass, synthetic and cellulosic modified with a synthetic, said substrate being impregnated and bonded with about 15 to 65 weight percent of a cured resole resin solids containing about 1 to 30 parts by weight of a boron compound accelerator based on 100 parts of said resole resin solids, the remainder, up to 100% by weight of said laminate being substrate, said boron compound being selected from the group consisting of boric acid, diammonium tetraborate, diammonium octaborate, diammonium pentaborate and mixtures thereof.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
49 words
A laminate of claim 1 wherein said resole resin comprises the reaction product of formaldehyde and a phenol, said phenol selected from the group of phenol, substituted phenols, substituted phenol mixture and mixtures thereof in a mol ratio 1.0 to 3.0, reacted in the presence of a basic catalyst.
Claim 4
Dependent Claim
