Product Description

Trigonox® K-80 Cumyl hydroperoxide, 80% in aromatic solvent mixture

Product Description

 

K-80 Storage

Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time.

To minimize the loss of quality, Nouryon recommends a

maximum storage temperature (Ts max.) for each

organic peroxide product.

For TrigonoxK-80

Ts  max. =40°C and

Ts  min. =-30°C to prevent crystallization

 

K-80 NOTE:

When stored under these recommended storage conditions,TrigonoxK-80 will remain within

the Nouryon specifications for a period of at least 6 months after delivery.

 

 

 

K-80 Thermal stability

Organic peroxides are thermally unstable substances, which may undergo self-accelerating decomposition. The lowest temperature at which self-accelerating 
decomposition of a substance in the original packaging may  occur is the Self-Accelerating Decomposition 
Temperature (SADT). The SADT is determined on the 
basis of the Heat Accumulation Storage Test.

For Trigonox K-80                    SADT :75°C

The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic 
peroxides (see Recommendations on the Transport of 
Dangerous Goods,    Manual of Tests and Criteria - United Nations, New York and Geneva).

 

K-80 Safety and handling
Keep containers tightly closed. Store and handle Trigonox K-80 in a dry well- ventilated 
place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room.
Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, driers and metal soaps).
Please refer to the Material Safety Data Sheet (MSDS) for further information on the safe storage, use and
handling of Trigonox K-80. This information should be 
thoroughly reviewed prior to acceptance of this product.

Major decomposition products

Acetophenone, 2-Phenylisopropanol, Methane

 

Dosage	Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:
	Trigonox K-80		1 - 3 phr
	Accelerator VN-2		0.5 - 3 phr
	Accelerator NL-51P		0.1 - 0.5 phr
	* phr = parts per hundred resin
Cure Characteristics in pure UP resin	In a high reactive standard orthophthalic resin the following characteristics were determined:
	Activation temperature	1 phr Trigonox K-80	90°C
	Gel times at 20°C	1.5 phr Trigonox K-80 + 0.5 phr Acc. NL-51P	1380 min
		The following table indicates the performance of Trigonox K-80, in comparison with usual ButanoxÒ  systems, in a vinylester resin:
		Vinylester resin	100	100
		Trigonox K-80	2	-
		Trigonox K-80	-	2
		Accelerator NL-49P	-	2
		Accelerator NL-49P	-	2
		Accelerator VN-2	1	-
		Gel time at 20°C (min.)	12	17
	Cure at 20°C in 2 mm laminate	Time to achieve a Barcol hardness (934- 1) of 25-30 in hours	0.5	1
		Residual styrene (%)
		after 24 hours	4.8	7.1
		after   1 month	0.6	4.2
Cure Characteristics at elevated temperatures	The fact that processing times of several hours can be achieved with low cobalt dosages makes Trigonox K-80 very suitable for use in e.g.filament winding techniques. Simulating the manufacture of a pipe at 50°C consisting of a laminate of 10 mm with a glass content of 30% and an epoxy vinylester resin gave the following results:
	Trigonox K-80		2 phr
	Accelerator NL-49P		0.25 phr
	Gel time at 20°C		330 minutes
	Curing data at 50°C	Gel time	62 minutes
		Time to Peak	118 minutes
		Peak exotherm	117 °C
		Barcol hardness (934- 1) 10 minutes after reaching the peak: 50

Application

☆Trigonox K-80 can be used for various polymerization reactions; for the copolymerization of styrene and butadiene for 
the polymerization of acrylonitrile,acrylic esters,vinyl chloride,styrene,vinyl toluene,isoprene,diallyl phthalate and unsaturated polyesters.
☆In this bulletin we restrict ourselves to the application of Trigonox K-80 as curing agent for unsaturated polyester
resins.
☆Without the addition of an accelerator the polymerization starts only above the activation temperature of 90°C. For the cure at lower temperature Trigonox K-80 must be accelerated by cobalt or vanadium. ☆Together with cobalt accelerators the gel time at room temperature is very long and is therefore particularly suitable 
for those applications where a long production time is required, for instance in the production of large parts and in 
filament winding. Sufficiently fast gel and cure times are only obtained above 35°C.
☆Together with vanadium accelerators Trigonox K-80 gives a short gel time and a fast cure at room temperature. This can be improved further by adding a special promotor, like pyruvic acid. With such a system it is possible to get a fast 
cure of UP resins, even at low temperature. Also  for resins like vinylester resin, these combinations are very suitable.
