Safety precautions:

(1) Keep away from fire, open flame and heat source.

(2) Avoid contact with reducing agents (e.g. amines), acids, bases and heavy metal compounds (e.g. accelerators, metal soaps, etc.)

(3) Please refer to the MSDS of this product.

Uses:

(1) Styrene polymerization:

TBEC can be used in the polymerization reaction of styrene and styrene copolymer, the polymerization reaction temperature range is 100-130℃. In the ontology polymerization, the

TBEC is beneficial to increase the reaction rate.

In aqueous suspension polymerization process, the use of TBEC can reduce the residual amount of styrene monomer in the final stage of the reaction.

(2) Polymerization of acrylates and methacrylates:

TBEC can be used in the polymerization reaction of acrylates or methacrylates with a polymerization reaction temperature of 100-170°C.

(3) Curing of thermosetting resins:

TBEC can be used for the curing of aliphatic unsaturated polyesters at high temperatures.

TBEC is the curing agent for UP resin hot molding process (SMC, BMC, ZMC, etc.), the temperature range of 120-170 ℃, the products are resistant to

Good resistance, safe and environmentally friendly.

Storage conditions:

Keep the package closed and in good ventilation, the maximum storage temperature is 20 ℃, avoid and reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soap).

Avoid the use of reducing agents such as amines, acids, alkalis, heavy metal compounds (accelerators and metal soaps), and strictly forbid to divide and take in the warehouse.

Storage stability:

Stored according to the conditions prompted by the manufacturer, the product in three months to ensure that the factory technical standards.

Fire extinguishing:

Small fires need to be extinguished with dry powder or carbon dioxide extinguishers, while spraying with large amounts of water to prevent re-ignition. Large fires need to be sprayed with a large amount of water at a safe distance away

Shot, and notify the fire department.
