Abstract
Laboratory vessels are coated on an operational surface thereof with a hydrophobic coating polymer or reactive monomer to form a coating having an exposed surface populated with 30% by area or more terminal trifluoromethyl groups. Laboratory vessels coated with such coating solutions are provided having extremely low surface energies and high resistance to solvent attack. Methods of forming hydrophobic coatings on laboratory vessels are also provided and include methods of forming exposed coating surfaces having populations of from about 30% by area to 100% by area trifluoromethyl groups. The hydrophobic coatings may be prepared from solutions, suspensions or powdered materials containing a fluoroalkyl ethylenically unsaturated monomer substantially free of any crosslinking, having from about 3 to about 20 carbon atoms, and containing at least one terminal trifluoromethyl group, or containing a polymerization product of such a monomer. The trifluoromethyl containing component may instead be preinjected or coinjected onto a surface of a molded vessel.
