Flexer® Epoxy Flexibilizer
特征
使环氧树脂为半刚性 - 制成不易碎的物件，并提高抗冲击性。
选择预期结果 - 固化后环氧体系的物理和应用性能可能会随着添加量的增加而降低。一旦添加了Flexer®，产品将保持柔软性。
较低的粘度 - 有助于对可浇注树脂进行脱气，并有助于层压环氧树脂润湿复合增强材料（玻璃纤维布，Kevlar等）。
说明
Read and follow directions given on the technical bulletin for the EpoxAcast® or EpoxAmite® product before adding Flexer®.
Store and use all materials at 73°F / 23°C. Avoid breathing fumes - use in a well ventilated area at minimum. NIOSH approved respirator is recommended. Wear safety glasses, long sleeves and rubber gloves to minimize skin contact.
MEASURING AND MIXING
Flexer® Epoxy Flexibilizer is added by weight as a percentage of Part A. An accurate gram scale is required. Add Flexibilizer to Part A of the epoxy system and mix thoroughly. Add the appropriate amount of Part B and mix all components thoroughly.
Example:
Goal – Soften EpoxAcast 650 from a Shore 90D to a Shore 60D. Normal mix ratio: 100A:12B
| EpoxAcast® 650 Part A |
+ | Flexer® Flexibilizer |
Mix Thoroughly |
+ | EpoxAcast® 650 Part B |

| 1,000 grams | 150 grams | 120 grams |
Important: Working time and cure time will be increased in proportion to the amount of Flexibilizer added. Physical and performance properties (including Shore hardness) of cured epoxy system may be lower in proportion to the amount of Flexer® added. Do not exceed recommended loading maximum of 20% of epoxy Part A, as the epoxy system may not cure.

Because no two applications are quite the same, a small test application to determine suitability is recommended if performance of this material is in question.
