Mowilith® LDM 1871

Mowilith LDM 1871 is an aqueous copolymer dispersion primarily composed of vinyl acetate and ethylene, with added polyvinyl alcohol and surfactants. It is specifically designed as a raw material for the paints and coatings industry, particularly for interior applications requiring low odor and low emission formulations.

Key Characteristics and Uses:

1. Composition: Contains vinyl acetate and ethylene copolymers, which contribute to its film-forming properties and flexibility.
2. Applications:
   • Interior Coatings: Used in formulations for low emission interior matt and satin paints, masonry paints, resin-bound plasters, textured coatings, and primers.
   • Compatibility: Shows good compatibility with a variety of thickeners, defoamers, fillers, and pigments, though acrylic thickeners may affect stability.
   • Performance: Provides outstanding scrub resistance and anti-blocking properties, ensuring excellent workability during application.
3. Technical Specifications:
   • Solids Content: Typically between 52% to 54%.
   • Viscosity: Brookfield viscosity at 25°C ranges from 1000 to 4000 mPas.
   • pH Value: Falls within the range of 4.0 to 5.0.
   • Particle Size: Has a particle size ranging approximately from 0.10 to 0.45 µm.
   • Film Formation: Forms a slightly opaque, crack-free, and flexible polymer film.
4. Storage and Handling: Requires storage between 5°C and 35°C to maintain stability, avoiding direct sunlight and frost. Initial biocides help prevent microbial growth, and additional preservatives are recommended after initial opening.
5. Safety and Regulatory: Users are advised to follow standard safety precautions for handling aqueous polymer emulsions. Detailed safety data sheets are available for regulatory compliance.

In summary, Mowilith LDM 1871 from Celanese is a versatile aqueous dispersion tailored for formulating low odor and low emission interior coatings. Its composition and properties make it suitable for a wide range of applications within the paints and coatings industry, offering excellent performance and ease of formulation.
