Methyl tetrahydrophthalic anhydride curative agent(MeTHPA) |
Our company adopts the up-to-date
process technique to produce Methyl tetrahydrophthalic anhydride solidifying
agent. Its features are:
- low freezing solid, operate at normal temperature, good operation
condition and long use time, especially applicable for being used in
the cold regions.
- light color and lustre, can be directly prepared into all kinds of
colorful hardened products.
- low toxicity, only one twentieth to one fortieth of amine-type solidifying
agent .
Uses:
FHY908 solidifying agent is used in casting, laminating, dipping, mold
pressing, adhesive and winding process, also used in electromechanical
and electronic products, in insulative bushing, oil pipeline and fishing
machine, etc. FHY910 solidifying agent is widely used in the casting of
line output transformer, can make the surface of cast matters not yellowing.
FHY912 solidifying agent is of lighter color and lustre, low air bubble.
FHY905 solidifying agent is the special B ingredient used for drip-dipping
insulating paint
1146((or 202).
Referenced proportioning and solidifying process:
1. Formulation: E-51 epoxy resin: FHY series solidifying agent: accelerant=100:
75-80: 0.1-0.5.
2. Process: 60-80
°C debubbling+100
°C /2hrs+130
°C /6hrs,
the subsequent temperature and time is decided according to the volume
of solidified matter.
