With one: to treat the drug of choice for leprosy, can also be associated with other inhibition of leprosy drug applications
Use way 2: epoxy resin curing agent.Gas chromatographic stationary liquid (highest use temperature 180 ℃, the solvent of acetone).Separate analysis of phenolic compounds.
This product is used as the curing agent of epoxy resin, low reactivity, long service life (about 1 year).Suitable for casting products, laminated products, adhesives and so on.General dosage 30 ~ 35.Curing conditions: 110 ~ 200 ℃ / 2 ~ 4 h.Cured with excellent thermal stability and outstanding chemical stability, high heat deformation temperature (170 ~ 180 ℃).Because of this product with the mixture of resin viscosity is very high, so when used for casting products are generally in more than 100 ℃.
