CASE Ingredients Features
Product Benefits
  • WANNATE® HTBL-275MS can be used in the formulation of weather-stable, lightfast, chemically resistant and highly heat-stable one-component polyurethane stoving coatings for use in automotive finishing.
  • Compared with polyisocyanates blocked with butanone oxime, WANNATE® HTBL-275MS allows a reduction in the stoving temperature of approx. 10 °C, with no decrease in solvent and chemical resistance.

Storage & Handling

Storage and Shelf Life Conditions
  • Store in tightly closed containers to prevent moisture contamination.
  • Recommended storage temperature: 0 ~ 30 °C.
  • Protect from moisture, heat and foreign material.
  • General information: Storage at higher temperatures will result in increase of color and viscosity. Storage at significant lower temperatures will result in solidification. This solidification is reversible by briefly heating the product without adversely affecting the quality of the product.
  • It can remain stable at least for 6 months at room temperature if stored properly.
