Abstract

A composition comprising a base oil in an amount from 5 to 95 wt %, an ethylene vinyl acetate copolymer resin, and an ester-soluble tackifying resin; wherein the ethylene vinyl acetate copolymer resin is present in an amount from 5 to 95 wt % based on the total weight of the ethylene vinyl acetate copolymer resin and the ester-soluble tackifying resin is provided. Methods for assembling or lubricating turbine engines are also provided.

First claim

That which is claimed is:

1. A method for assembling or lubricating a turbine engine comprising:
applying a composition between two or more turbine engine components, wherein the composition comprises:
a base oil in an amount from 5 to 95 wt % based on the total weight of the composition;
an ethylene vinyl acetate copolymer resin; and
an ester-soluble tackifying resin;

wherein the ethylene vinyl acetate copolymer resin is present in an amount from 5 to 95 wt % based on the total weight of the ethylene vinyl acetate copolymer resin and the ester-soluble tackifying resin.

2. The method according to claim 1 , wherein the base oil comprises an alkylated naphthalene-based oil.

3. The method according to claim 1 , wherein the base oil comprises a polyol ester oil.

4. The method according to claim 1 , wherein the base oil comprises an olefin ester copolymer based oil.

5. The method according to claim 1 , wherein the base oil comprises a polyalphaolefinic oil.

6. The method according to claim 1 , wherein the ester-soluble tackifying resin is a terpene phenolic resin.

7. The method according to claim 1 , wherein the composition is soluble in a SAE AS5780 qualified oil such that when 2 wt % of the composition is mixed into the SAE AS5780 qualified oil with stirring at 180° C. to form a mixture, followed by cooling at room temperature, the mixture will remain as one phase greater than 8 hours and with no precipitate for greater than 24 hours.
