Safety
Good workplace ventilation is to be ensured during processing. At the same time, the employer’s liability insurance association’s industrial hygiene safety regulations regarding the handling of reaction resins and their hardeners are to be observed. Please take heed of the appropriate safety data sheets.
The material should be stored flat and in a dry place. Temperature variations should be avoided during storage and transportation.
The product should be machined at ambient room temperature (68-77°F (20-25°C)).
