Product Description

WL-3120U is a high-reactive activity and medium viscosity inter-phenyl-neoosaccharide type unsaturated polyester resin. It can use magnesium oxide to stabilize and thickened. It can be solidified by ultraviolet lights. It has good glass fiber infiltration and mechanical performance good. Comply with the standard requirements of the "Inner Line House" standard for "Urban Drainage Pipelines"。

Application

The WL-3120U resin is balanced with the glass fiber and has a high mechanical strength. It is suitable for the application of ultraviolet optical curing non-excavation pipe restoration engineering (CIPP).

Instructions and precautions

1. WL-3120U is strictly prohibited from mixing water, oil, dust, dust and other foreign bodies. The resin and the water are overwhelmed, and the resin is not available after mixing.

2. Be sure to wear protective supplies (masks, gloves, etc.) during operation.

3. This product is ultraviolet curing product, which is sensitive to ultraviolet light, so it is prohibited from exposed to light.

Recommendations

1. WL-3120U resin can use magnesium oxide paste thickening. The thickening rate is directly related to magnesium oxide paste numbers and dosage. It is recommended to test small batches before use.

2. WL-3120U resin can use mercury lamps and UV-LED lights. If other light sources are solidified, it is recommended to test small batches in advance.


Storage conditions

1. Before using, the resin should be stored in the original packaging (avoid the damage of the barrel and the barrel) in a dry room below 25 ° C.

2. The increase in temperature and light irradiation will significantly reduce the storage period. Direct sunlight and stay away from the heat source should be avoided during storage.

3. The unsaturated polyester resin liquid containing the styrene is flammable, and it should be stayed away from Minghuo when storing. Pay attention to the security data table.
