packing:

The standard packaging for LQ-TBEC is a PE plastic bucket with a net weight of 25 kilograms. It can also be packaged according to the specifications requested by the user.

LQ-TBEC is a Class D liquid organic peroxide, cargo classification: 5.2, United Nations number: 3105, packaging for Class II dangerous goods

Safety precautions:

(1) Keep away from sparks, open flames, and heat sources.

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

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

Purpose:

(1) Polymerization of styrene:

TBEC can be used for the polymerization reaction of styrene and styrene copolymers, with a polymerization temperature range of 100-130 ℃. In bulk polymerization, TBEC is beneficial for increasing the reaction rate. In the 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 acrylate and methacrylate:

TBEC can be used for the polymerization reaction of acrylic or methacrylate at a temperature of 100-170 ℃.

(3)Curing of thermosetting resins:

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

TBEC is the preferred curing agent for UP resin hot molding process (SMC, BMC, ZMC, etc.), with a temperature range of 120-170 ℃, good product resistance, safety and environmental protection.

Storage conditions:

Keep the packaging sealed and in a well ventilated state, with a maximum storage temperature of 25 ℃. Avoid mixing with reducing agents such as amines, acids, alkalis, and heavy metal compounds (accelerators and metal soaps). It is strictly prohibited to pack or use in the warehouse.

Storage stability:

Store according to the manufacturer's instructions, and the product can meet the factory technical standards within three months.

Fire extinguishing:

Small fires need to be extinguished with dry powder or carbon dioxide fire extinguishers, and a large amount of water should be sprayed to prevent reignition. A large fire requires spraying a large amount of water from a safe distance.
