Substrates Markets Substrates Markets
• Wood• Metal• Cements• Ceramics
• Furniture• Flooring• Architecture• Decorative
• Wood• Wood laminates• Metal• Mixed Substrates
• Furniture• Flooring• Nonwovens / Hygiene• Foams• Electronics• Packaging: Rigid & Flexible
Performance Benefits
• Excellent oil, grease, and solvent resistance• Controlled functionality and branching
- Hydroxy, acid, unsaturated, acrylate• High hardness polyurethanes
• In adhesives, tailored open times in hot melts to modify work-life
• Excellent adhesion• Renewably-sourced building block
Building upon decades spent advancing materials chemistry innovation, NatureWorks offers solutions based on lactides and lactide intermediates that help innovators within the coatings, adhesives, sealants, and elastomers (C.A.S.E.), toner and surfactant industries realize:
Significant, measurable product performance benefits
Move through the R&D process more efficiently and with minimal risk
Decrease systems costs via an optimized supply chain
We achieve this by coupling tunable Vercet™ lactide-based chemistries with the knowledge of scientists and engineers who understand how to dial in the full capabilities of this versatile product line.
