Performance index of castable body:
| Product name | Tensile Strength(Mpa) | Breaking Elongation(%) | Bending Strength(Mpa) | Bending modulus(Gpa) |
Distortion Temperature(℃) | Barcol hardness |
| YBS-991 | 50 | 2.5 | 90 | 3.2 | 55 | 45 |
Product Application：
YBS-991 unsaturated polyester resin, suitable for making all kinds of artificial marble products, such as sanitary ware, flat plates and ornaments.
Storage & Use：
1、Before use, the resin should be in the original packaging (avoid breakage of the barrel and barrel),25℃ below the dry indoor storage period of three months. Keep the barrel sealed to prevent moisture from invading and tighten the lid.
2、The increase of temperature and light exposure will significantly shorten the storage period, storage should be away from heat sources and avoid direct sunlight.
3、Unsaturated polyester resin containing styrene is flammable and stored away from open fire.
4、If the resin is not used properly, it will cause injury. Avoid contact with skin and eyes. Wear necessary protective equipment and clothing. For product safety instructions, see Yibeisen's "resin safety instructions (MSDS)"
