Features/Applications
The resulting wood lacquer is particularly fast-drying and easy to sand. A full-bodied clear or pigmented coat can be obtained in just a few coats.
compatibility
Desmodur HL BA is compatible with many Desmophen polyesters and has only limited compatibility with hydroxyacrylates. In general, Desmodur HL BA has good compatibility with standard Desmodur products.
Solubility/Dilution
Desmodur® HL BA generally has good compatibility with the following solvents. However, the resulting solutions must be tested for storage stability. Desmodur HL BA can be diluted with ethyl acetate, butyl acetate and 1-methoxypropyl acetate-2. Aromatic solvents are not true solvents and have limited compatibility as diluents. Solutions with a low content of binders will experience turbidity and precipitation after prolonged storage. Polyurethane grade solvents should be used (low water content
at 0.05%). These solvents should not contain reactive groups.
store
- Store in original Covestro airtight containers.
- Recommended storage temperature: 0-30℃.
- Avoid moisture, heat and foreign substances.
General Information: This product is moisture sensitive. High temperature storage will result in an increase in viscosity and a decrease in NCO content.
storage time
Covestro declares that the product complies with the above "specification or characteristic values" for a period of 6 months from the date of shipment stated on the shipping document, provided that the product is stored in full compliance with the requirements in the "Storage" clause above and handled properly Specifications or characteristic values stated in the Terms (as applicable). The fact that a product exceeds the 6-month period above does not mean that it no longer meets the specifications or the values set in the characteristic values. However, Covestro recommends that products older than 6 months from the date of shipment be tested before use to confirm that they still meet the specifications or set values in the characteristic values. Covestro makes no commitments for products older than 6 months from the date of shipment, and accepts no responsibility or liability for non-conformance to specifications or set values in characteristic values.
