From $3,70000Unit price /Unavailable
Sorbents & Additives for Coatings, Adhesives & Sealants
Explore functional sorbents, molecular sieves, and mineral additives for coatings, adhesives, sealants, and related formulations. These materials support moisture control, rheology, absorption, surface quality, and formulation stability across polyurethane, industrial coating, adhesive, and specialty chemical systems.
How They’re Used
- Moisture scavenging: Activated molecular sieve powders adsorb trace moisture within polyurethane and other moisture-sensitive formulations.
- Bubble & defect control: Moisture control can help limit unwanted reactions that contribute to gassing, bubbles, and surface defects in polyurethane systems.
- Flow & rheology: Functional silicas and clays can support viscosity, suspension, flow, and application characteristics.
- Absorption & formulation support: Porous mineral materials provide high surface area for adsorption, carrier functionality, and process-specific formulation needs.
Common Applications
- Polyurethane coatings: Molecular sieve powders for trace-moisture adsorption in moisture-sensitive coating systems.
- Adhesives & sealants: Moisture-control additives for polyurethane and other reactive formulations.
- Industrial paints & finishes: Mineral additives for rheology, adsorption, surface characteristics, and formulation stability.
- Specialty formulations: Silica, clay, and molecular sieve grades for applications requiring controlled particle size, surface area, or selective adsorption.
Molecular Sieves in Polyurethane Formulations
Trace moisture can react with isocyanates in polyurethane systems and generate carbon dioxide, contributing to gassing, bubbles, and surface defects. Activated molecular sieve powders can be incorporated directly into the formulation to adsorb moisture before it interferes with the polyurethane reaction. Different pore sizes and grades provide formulators with options based on moisture adsorption, selectivity, viscosity, and pot-life requirements.
