It is one of cyclic-amidine compounds, equivalent to HUELS AG B31.
RB31 is a low temperature and fast curing agent applying to high-activated epoxy-resin powder, and it can be rapidly solidified in 1015 minutes at 1400 or in 35 minutes at 2000.
For preparation of aid to low-temperature solidified saturated carboxyl-polyester, for example, in production of polyester resin, it is added 0.10.5% (of polyester weight) into the reactor at the stage of input, and stirred well distributed, a special low-temperature solidified polyester resin can be produced. Compared with the same kind, it can be lowered about 200 for solidification in normal atmospheric temperature.
Appearance: pale yellow crystal powder.
Melting range: 950. 1010.
It is an accelerating agent to pure epoxy-resin powder or compound epoxy / polyester resin powder for cyanoguanidine as hardener.
Package:20kgs/polyethylene kraft paper bag.
Storage: Store in cool and dry place to avoid contacting other chemical products. Keep away from heat and fire.
