·加工
在使用之前,A组分树脂需在大桶内均匀混合。
两种原料被设计作为标准剂量和计量装置的双组分聚氨酯使用。最优发泡温度在20 - 25°C。热
处理(加热)加速硬化过程。
表面的粘附力可以通过介质增强 (底涂剂或者物理预处理)或者避免脱模剂。
存储
两个组份原料必须储存在密封容器中。绝对远离水和大气湿度(必要时使用硅胶密封容器)。
存储温度不应超过+ 30°C或低于+ 10°C。
容器在使用后必须立即密封. 打开新桶需要尽快用完,如果注意这些细节,原料可以储藏6个
月。

Processing
Homogenise the resin (A-component) well in the drum before use.
Both materials are designed to use on a standard dosing and metering unit for two component
polyurethane gaskets. The optimum ambient temperature during processing is 20 - 25°C.
Thermal treatment (tempering) accelerates the hardening process. The adhesion to the
substrate can be enhanced by bonding agents (primers or physical pre-treatments) or
prevented by release agents.
Storage
Both components must be stored in tightly sealed containers. Absolutely keep away from
water and atmospheric humidity (use silica gel cartridge if necessary). The storage
temperature should not exceed +30°C or drop below +10°C. The containers must
immediately be resealed after use. Opened drums are to be used up promptly. If these
instructions are observed, the materials are storable at least 6 months.
Industrial safety
The hardener component contains isocyanate. It may cause irritation to the skin, eyes and
respiratory tract, sensibilisation of the skin and respiratory tract as a result of chronic
exposure and also trigger allergic reactions. Additional information is found in the safety
data sheet. Please ensure cleanliness and good ventilation in the workplace. Protect eyes and
skin. Dab off accidental splashes to the skin and remove with soapy water. In case of
splashes into the eyes, immediately rinse under running water for 10-15 minutes and see a
doctor.
Please also take note of:
- the risk phrases and safety phrases on the drums.
