Abstract
A paint comprising a solution of an internal phase comprising pigment and latex resin and an external phase comprising an amine soluble resin dissolved in water is disclosed. The amine soluble resin has a molecular weight sufficiently high that it imparts desirable film properties while maintaining surface applicability of the paint. Upon evaporation of the water, the external phase forms a substantially continuous film encapsulating the internal phase. The invention also comprehends a novel method of paint formulation.
Claims29
A paint solution substantially free of crosslinking consisting of:
- an internal phase comprising pigment and latex resin;
- and
- an external phase comprising an amine-soluble resin dissolved in water, said amine-soluble resin having a molecular weight sufficiently high that said amine soluble resin imparts an improvement in desirable film properties including hardness, flexibility, adhesion, water resistance and a high volume of solids to said paint while maintaining surface applicability of said paint, said external phase being effective in forming a substantially continuous film encapsulating said internal phase upon evaporation of said water at ambient temperature.
A method of formulating a paint capable of being set without the use of a crosslinking agent or the addition of heat comprising the steps of:
- dispersing an amine-soluble resin and pigment at high speed to form a mixture, said amine soluble resin having a molecular weight sufficiently high that said amine soluble resin imparts in improvement in desirable film properties including hardness, flexibility, adhesion, water resistance and a high volume of solids to said paint while maintaining surface applicability of said paint;
- and
- mixing a latex resin with said mixture.
