Wood expands and contracts in response to temperature and humidity changes, making wood coatings a challenge. What’s more, those coatings are essential to protect the wood from damaging moisture penetration. That’s why wood coatings need flexibility and water resistance. Hardness is also useful, as is block resistance to prevent coated surfaces from sticking to one another. Outdoor applications often benefit from protection against the UV light that causes degradation.
MCP has developed both styrene acrylic and carboxylated styrene-butadiene polymers for coating wood substrates. An area where MCP products have demonstrated outstanding performance is in the OSB edge-seal coatings within the Construction market.
