Improved coating formulations containing silica based matting agents in the form of a blend of low pore volume silica particles and high pore volume silica particles are disclosed. The matting formulations are useful in waterborne coating compositions to provide exceptional properties to a coated substrate. Films resulting from the coating formulations containing silica-based matting agents on a substrate unexpectedly provide improved chemical resistance to the surface of the substrate, in particular wood or plastics. Methods of making and using the silica-based matting formulations are also disclosed.

The present disclosure provides for a coating formulation that includes a pigment, an organic aqueous emulsion and an organophosphonic acid of the formula:

##STR00001##

where R is a saturated or unsaturated alkyl having 2 to 10 carbon atoms or a substituted or unsubstituted aryl having 5 to 10 carbon atoms. The coating formulation can be used in forming a topcoat in an exterior insulation and finish system (EIFS). The present disclosure also provides for a method of forming a topcoat on a surface of the EIFS that helps to protect the underlayment of the EIFS against both weathering and moisture while helping to maintain color retention.

A multi-part water-borne coating composition is provided. The multi-part composition includes water, a first part, and a second part. The first part comprises (a1) a core-shell latex copolymer having pendant hydroxyl and pendant carbonyl groups. The second part comprises (b1) at least one polyisocyanate compound having pendant NCO groups. The multi-part composition also includes at least one polyhydrazide compound having at least two hydrazide groups of the formula C(O)NHN(R.sup.h)(R.sup.i), wherein R.sup.h and R.sup.i are independently H or C.sub.1-C.sub.12 alkyl. The molar ratio of hydroxyl groups to NCO groups in the composition is from 5:1 to 1:5. The molar ratio of hydrazide groups to carbonyl groups in the composition is from 5:1 to 1:5.
