Abstract
Disclosed herein are methods for pasteurizing or sterilizing architectural coating compositions using high pressure processing (HPP) with or without heat, radiation or other energy sources without additionally polymerizing the compositions, and storing same.
Claims20
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- (ii) applying a pressure ranging from 50 MPa to 1,000 MPa, to said architectural coating composition for a duration of up to 10 minutes;
- and
- (iii) then storing the architectural coating composition in paint containers that are sold to consumers.
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- and
- (ii) applying a pressure ranging from 300 MPa to 700 MPa, to said architectural coating composition for a duration of up to 10 minutes.
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- and
- (ii) applying a pressure ranging from 50 MPa to 1,000 MPa, to said architectural coating composition for a duration ranging from 1 minute to 5 minutes.
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- and
- (ii) applying a pressure ranging from 50 MPa to 1,000 MPa, to said architectural coating composition for a duration of up to 10 minutes;
- wherein the architectural coating composition is stored in a flexible container before step (ii) and the flexible container transfers the pressure to the architectural coating composition contained therein.
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- (ii) applying a pressure ranging from 50 MPa to 1,000 MPa, to said architectural coating composition for a duration of up to 10 minutes;
- and
- (iii) applying a heating step, either simultaneously or sequentially with step (ii).
A method for reducing biological agents in an architectural coating composition, including at least one of paint and stain compositions, comprising the steps of
- (i) preparing the architectural coating composition;
- (ii) applying a pressure ranging from 50 MPa to 1,000 MPa, to said architectural coating composition for a duration of up to 10 minutes;
- and
- (iii) applying a second pressure treating step at the same pressure and duration as those from step (ii).
