Product characteristics
POLUSYN BK3165 is a closed type IPDI curing agent that does not contain NCO active ingredients at room temperature. It can react and crosslink with hydroxyl resin to form a film after high temperature unsealing. Its unsealing temperature is about 120 ℃. This product has excellent flexibility and substrate adhesion, and can be used to enhance the toughness of amino resin, improve the adhesion of paint film, and resist boiling.
Compatibility
POLUSYN BK3165 has good compatibility with most resins and solvents. Before the product is applied in production, the compatibility between materials should be tested in advance.
Storage
The product must be stored in a cool and dry environment, with a shelf life of 1 year (calculated from the date of production) under sealed packaging conditions.
