TM-109
|
Features and main uses:
|
|
TM-109 unsaturated polyester resin is a kind of high activity o-benzene type BMC resin. It has the characteristics of high mechanical strength, good toughness, good heat resistance, high thermal strength, low shrinkage and fast curing. The surface of BMC pressed parts made of tm-109 resin is bright, smooth, high mechanical strength and excellent electrical performance.

Matters needing attention:
|
|
1. Due to the high temperature in summer, please add proper amount of polymerization inhibitor to ensure the storage stability of BMC.
|
|
2. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months.
