A primer is a coating between the substrate and the top coat. The right primer provides excellent adhesion to these two points of contact. Along with adhesion, a primer needs flexibility and moisture resistance.
For a high quality moisture vapor barrier transmission primer MCP recommends carboxylated styrene-butadiene latexes. The combination of styrene and butadiene provides strength and flexibility while carboxylation promotes adhesion and water resistance.
MCP can provide recommended formulations based on our product offerings for your primer application.
Ecronova 6630 is an ambient cure all acrylic emulsion that provides good chemical and blocking resistance, high hardness and scratch resistance as well as good wetting of wooden substrates especially for furniture and industrial coatings.
Rovene 4009 is a styrene-butadiene emulsion polymer recommended for applications in specialty paper coatings where water, grease and oil resistance is needed.
Rovene 4076 is a medium-firm, carboxylated styrene-butadiene emulsion recommended for use in architectural coatings and interior primers for dry wall application where low perm ratings are required.
Rovene 4002 is a medium-firm, carboxylated styrene-butadiene emulsion designed to have good freeze-thaw stability and low odor characteristics, when used in trade sales coatings.
Rovene 4019 is a styrene-butadiene emulsion polymer recommended for use in paper and paperboard coatings where a high degree of grease, oil and water resistance is needed.
