Styrene-acrylic polymers offer excellent hydrophobic characteristics, which means they have superior water resistance and moisture vapor transmission rate (MVTR) when compared to all-acrylic polymers. Also, styrene itself is a hydrophobic monomer, making it possible to produce styrene-acrylic polymers with low particle sizes. This results in polymers that are ideal for certain applications, such as primers for the construction industry or binders for paper coatings.
Properties of Acrylic Co-Polymers:
- Good weatherability and good stain resistance.
- Broad tensile/elongation balance.
- Ability to crosslink.
- High pigment-binding capacity.
- Ideal gloss, film strength, and resistance to removal by detergents.
- Good adhesion to common substrates, including galvanized steel, aluminum, and wood.
