Abstract
Sets of prepaints wherein at least one set member is in solid form, methods of formulating paint lines using the sets of prepaints, and a method of formulating a range of paints from the sets of prepaints, where the paint lines and ranges of paints are useful as road marking coatings, architectural coatings, industrial coatings, graphic art coatings, non-cementitious aggregate finish coatings, elastomeric coatings, adhesives, caulks, sealants, and other building related products, are disclosed.
Claims8
A set of prepaints comprising:
- i. at least one opacifying prepaint x, comprising at least one opacifying pigment;
- ii. at least one extender prepaint y, comprising at least one extender pigment;
- and
- iii. at least one binder prepaint z, comprising at least one polymer binder;
- wherein at least one of said prepaints (i), (ii), and (iii) is a solid;
- wherein said prepaints (i), (ii), and (iii) are different, mutually compatible, and water dispersible;
- and
- wherein said set of prepaints is sufficient to form at least one paint line.
A method of forming at least one paint line, comprising:
- a. providing a set of mutually compatible, water dispersible prepaints, comprising:
- i. at least one prepaint x, comprising at least one opacifying pigment;
- ii. at least one prepaint y, comprising at least one extender pigment;
- and
- iii. at least one prepaint z, comprising at least one polymer binder;
- wherein at least one of said prepaints (i), (ii), and (iii) is a solid;
- and
- b. dispensing predetermined amounts of said solid prepaints into containers or application devices to form at least one paint line.
A method of forming a coating on a substrate, comprising the steps of:
- a. providing a set of mutually compatible, water dispersible prepaints, comprising:
- i. at least one prepaint x, comprising at least one opacifying pigment;
- ii. at least one prepaint y, comprising at least one extender pigment;
- and
- iii. at least one prepaint z, comprising at least one polymer binder;
- wherein said prepaints (i), (ii), and (iii) are solid;
- b. dispensing predetermined amounts of said solid prepaints into containers or application devices to form at least one paint line;
- c. dispersing said solid prepaints in an aqueous medium;
- d. applying said dispersion to a substrate;
- and
- e. drying said dispersion to form a coating.
A method of forming a range of paints comprising at least two paint lines, said method comprising the steps of:
- a. providing a set of mutually compatible, water dispersible, prepaints sufficient to formulate at least two paint lines, comprising:
- i. at least one prepaint x, comprising at least one opacifying pigment;
- ii. at least one prepaint y, comprising at least one extender pigment;
- iii. at least one prepaint z, comprising at least one polymer binder;
- and
- iv. at least one additional, opacifying, extender, or polymer binder prepaint which is different from prepaints x, y, and z;
- wherein at least one of said prepaints (i), (ii), (iii) and (iv) is a solid;
- and
- b. dispensing a predetermined amount of each of the prepaints into containers or application devices to form a range of paints.
