Note: 1. The preparation method is in accordance with GB / T8237-2005, curing system: Accelerator RCA 1.0%, curing agent Butanox M-50 1.0%.
|
|
2. Casting body post-treatment: room temperature×24 hours + 60 ℃×3 hours + 80 ℃×1 hours.

Reference formula:
|
|
HR-191 resin 100 copies；Curing agent （MEKPO） 1 ~ 2 copies (dosage depends on temperature)；Accelerator RCA 1~4 copies(dosage depends on temperature)

Matters needing attention:
|
|
1. In the selection of accelerators, high-efficiency colorless accelerators should be avoided, otherwise, poor curing of products will easily lead to surface sticking, and RCA and other special accelerators for FRP should be selected.
|
|
2. When the construction environment humidity is high or the temperature is high, it is easy to cause surface stickiness. At this time, rs-102 wax can be properly added, and the recommended addition amount is 0.4 ~ 0.8%
|
|
3. 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.
