The present invention includes aqueous coating compositions adapted to coat a plurality of sized glass fibers, glass fibers coated with the same and composites reinforced with the coated glass fibers. The coating composition includes (a) a polysiloxane having: (1) an alkyl substituent attached through a carbon atom directly to a silicon atom of the polysiloxane; (2) an alkoxy substituent attached through a carbon atom directly to a silicon atom of the polysiloxane, the alkoxy substituent having an alkyl group, an alkyl ether group and a terminal group selected from the group consisting of hydrogen and an alkoxy group having about 1 to about 8 carbon atoms; and (3) endblocking groups independently selected from the group consisting of a phenyl group, an alkyl group having about 1 to about 20 carbon atoms and combinations thereof, wherein the polysiloxane is essentially free of silicon-bonded hydroxy groups and alkoxy groups attached through an oxygen atom directly to a silicon atom of the polysiloxane, and (b) zero to less than about 50 weight percent on a total solids basis of a film-forming material capable of forming a uniform continuous coating on the glass fibers.

Secondary coating compositions for glass fibers, glass fibers coated

A novel amine-free antistatic agent comprising the reaction product of diethanolamine and a fatty acid or fatty acid ester, neutralized with a strong acid is disclosed, along with plastic composition treated with said antistatic composition, as well as a method for making the antistatic composition and methods for using it to produce plastic articles with antistatic properties.

Amine-free internal antistatic agent

The tendency of microporous material to discolor over a period of time when exposed to the atmosphere during normal usage can be reduced if the microporous material comprises whiteness retaining organic surface active agent.

Microporous material exhibiting increased whiteness retention

Antistatic additive composition comprises first quaternary ammonium salt represented by the formula ##STR1## where R.sup.1 is an aliphatic hydrocarbon group containing from about 11 to about 21 carbon atoms and X.sup.- is anion, and polyether represented by the formula
