Applications of LF-AF11 Amino-Modified Fluorosilicone Fluid
1. Reactive Modifier for Polyurethane Coatings and Inks
LF-AF11 may be evaluated as a reactive fluorosilicone modifier for polyurethane coatings and inks. Reaction of amino functionality with isocyanates can chemically introduce fluorosilicone segments into the binder. Depending on formulation and surface enrichment, it may contribute to oil and solvent resistance, slip, stain resistance and easy-clean performance. Compatibility, catalyst effects, cure response, adhesion and final film properties must be verified.
2. Polyurethane Elastomers, Plastics and Resin Modification
The product may be evaluated in polyurethane elastomers, plastics and other compatible resin systems where reactive amino functionality and a fluorosilicone segment are required. The amino-isocyanate reaction is typically rapid; addition sequence, moisture control, temperature and NCO index should be established by qualified formulators.
3. Textile and Surface-Treatment Formulation Development
Consistent with reactive amino-modified silicone chemistry, LF-AF11 may also be screened as a component of textile-finishing or surface-treatment formulations where lubricity, water repellency and affinity to substrates are sought together with oil- and solvent-resistant fluorosilicone character. This TDS does not establish wash durability, repellency ratings or use level; these must be determined for each substrate and process.
