Pultrusion Profile
|
Features and main uses：
|
|
HN-239 is an isophthalic unsaturated polyester resin. It has the characteristics of low viscosity, good wettability and fast curing. The products made of 239 are heat-resistant and have excellent mechanical properties, which are suitable for pultrusion process.
