Features
- Fast drying and hardness development. Figure 1 below details Persoz pendulum hardness performance.
- Coatings based on ENCOR® 2181 latex display excellent resistance to water and hydrophilic stains. Figure 2 below details chemical resistance performance.
- Produces films with high glass transition temperatures with excellent clarity and sanding properties.
- Sealers formulated with ENCOR® 2181 latex display excellent sandability and recoatability performance.
- Coatings display good film formation with fast-evaporating solvents with no permanent plasticizers.
- Contributes warm aspect in coatings applied to wood.
