Abstract
Abstract A non-aqueous sealant composition particularly adapted for use in the installation or sealing of fixed glass in vehicles. The composition has a thermoplastic rubber base, suitably modified by plasticizers, tackifyers and a cationic surfactant to provide a sealant system which displaces water from a wetted substrate to which it is applied, permitting it to be utilized under either wet or dry conditions.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
181 words
A non-aqueous, water-displacing sealant composition for application to vehicle glass joints and the like, comprising a homogeneous mixture of: (A) from 5% to 20% by weight of a thermoplastic rubber base, and (B) from 0.5% to 12% by weight of a liquid plasticizer selected from the group consisting of oxidation-resistant balsamic resins and aromatic hydrocarbons, and (C) from 1% to 20% by weight of a tackifying resin, and (D) from 0.1% to 3% by weight of an anti-oxidant for rubber, and (E) from 0.25% to 0.70% by weight of a cationic surfactant selected from the group consisting of imidazoline derivatives, and (F) from zero to 48% by weight of inert inorganic solids as fillers, and (G) from zero to 5% by weight of a bodying agent, and (H) from 20% to 70% by weight of a liquid solvent selected from the group consisting of aliphatic and aromatic hydrocarbons, and said composition being essentially free of water and being characterized by its ability to displace water, without absorption thereof into the composition, from a water-wetted substrate to which said sealant is applied.
