Hostavin 3058 LIQ is widely used in clearcoat automotive OEM systems based on acid-catalyzed resin system. It is highly recommended for high solid solventborne paint systems in the general industrial coatings market.
In addition it is suitable for alkyd based wood stains and varnishes requiring long lasting performance and as an acylated HALS, Hostavin 3058 LIQ is not instantly active and therefore does not interact with the photoinitiators during the UV curing process.
Recommended dosage level of Hostavin 3058 LIQ: 1.0 - 3.0% (active additive on solid resin)
Packaging and Handling
Steel drums 50 kg
Pallet 400 kg (8 drums)
Minimum shelf life is five years from the date of shipping when properly stored. Hostavin 3058 LIQ has the tendency to form a crystalline precipitate.
Heating the product to 50°C for a few hours will liquefy the product again. Other properties are not affected by this process. Store in a cool and dry place.
