It was developed as a low environmental impact binder for intermediate grade caulk formulations. Properties: As a broad application binder for caulks, VINNAPAS® EF539 provides a variety of benefits for the formulator including: - It is manufactured without the use of alkylphenol ethoxylates (APEOs).
- No formaldehyde or formaldehyde donors are intentionally added.
- It has a low glass transition temperature (Tg).
Application: VINNAPAS® EF539 meets the performance requirements of ASTM C-834 standard specifications for latex sealants, including artificial weathering, extension-recovery, low temperature flex, slump, tack free time and stain index.Information provided by Wacker Chemie AG. |
