Hardeners
Hardeners imported from Japan can be divided into two series of products: single-liquid latent hardeners and two-liquid hardeners. Single-liquid latent hardeners have the characteristics of curing at low temperature and conserving over 3 months, while two-liquid hardeners have the characteristics of environment protection, acid/alkaline durability and fast curing in 5 minutes.
