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
Steel drums 50 kg
Pallet 400 kg (8 drums)
Storage
Minimum shelf life is five years from the date of shipping when stored in a cool, dry place. Due to the nature of this products, the Gardner color may change overtime. Hostavin 3058 LIQ also tends to form a crystalline precipitate when stored in cold conditions, heating the product to 50°C for a few hours will re-liquify Hostastat 3058 LIQ to its original state. Neither the Gardner color change nor the reheating affects the products performance.
