Product Description

Butanox® LPT-IN 
Methyl ethyl ketone peroxide in diisononyl phthalate

Product Description

 

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 Butanox LPT-IN

Ts  max. =25°C

 

NOTE:

When stored under these recommended storage conditions,Butanox LPT-IN will remain within the

Nouryon specifications for a period of at least 6 

months after delivery.

 

 

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 Butanox LPT-IN                    SADT :60°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).

 

Safety and handling
Keep containers tightly closed. Store and handle Butanox® LPT-IN 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 Safety Data Sheet (SDS) for further information on the safe storage, use and handling of Butanox® LPT-IN. This information
should be thoroughly reviewed prior to acceptance of this product.

Major decomposition products

Carbon dioxide, water, acetic acid, formic acid,
propionic acid, methyl ethyl ketone. 

 

 

Dosage	Depending on working conditions, the following peroxide and accelerator dosage levels are recommended:
	Butanox LPT-IN		1 - 4 phr
	Accelerator NL-49P		0.5 - 3 phr
	Inhibitor NLC-10		0 - 0.2 phr
	* phr = parts per hundred resin
Cure Characteristics at ambient temperatures	In a high reactive standard orthophthalic resin in combination with Accelerator NL-49P (= 1% cobalt) the following application characteristics were determined:
	Gel times at 20°C	2 phr Butanox LPT-IN + 1.0 phr Acc. NL-49P	20 minutes
		2 phr Butanox M-50 + 1.0 phr Acc. NL-49P	7 minutes
	Cure of 4 mm laminates at 20°C	4 mm laminates have been made with a 450 g/m2 glass chopped strand mat. The glass content in the laminates is 30% (w/w).
		The following parameters were determined:
		☆Time-temperature curve
		☆Speed of cure expressed as the time to achieve a Barcol hardness (934-1) of 0-5 and 25-30 respectively
		☆Residual styrene content after 24 h at 20°C and a subsequent postcure of 8 h at 80°C
			Gel time min.	Time to peak min.	Peak exotherm°C
		2 phr Butanox LPT-IN + 1.0 phr Acc. NL-49P	24	54	41
		2 phr Butanox M-50 + 1.0 phr Acc. NL-49P	8	26	64
			Barcol 0-5h	Barcol 25-30h	Res.styrene24h 20°C%	Res.styrene+8h 80°C%
		2 phr Butanox LPT-IN + 1.0 phr Acc. NL-49P	3	13	6	<0.1
		2 phr Butanox M-50 + 1.0 phr Acc. NL-49P		1	5	<0.1
Cure Characteristics at elevated temperatures	The fact that processing times of several hours can be achieved with low cobalt dosages and small amounts of an inhibitor makes Butanox LPT-IN very suitable for use in e.g. filament winding techniques. Simulating the manufacture of a pipe at 70°C consisting of a laminate of 4 mm with a glass content of 30% gave the following results:
	Butanox LPT-IN		1.5 phr
	Accelerator NL-49P		0.3 phr
	Inhibitor NLC-10		0.2 phr
	Gel time at 20°C:		200 minutes
	Curing data at 70°C:
	Curing data at 70°C:		7 minutes
	Time to Peak		17 minutes
	Peak exotherm		119°C
	Barcol hardness 10 minutes after reaching the peak:		44
	Pot life at 20°C	Pot lives were determined of a mixture of Butanox LPT-IN and a non preaccelerated UP resin at 20°C.
		2 phr Butanox LPT-IN	11 h
		4 phr Butanox LPT-IN	6 h

Application

☆Butanox® LPT-IN is a methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. Butanox® LPT-IN gives in comparison with most other ketone peroxides a significantly longer gel time and is therefore particularly suitable for those applications where a long gel time or production time is required, for instance in the production of large parts and in filament winding.Also in areas with high ambient temperatures Butanox® LPT-IN is of particular interest. Butanox® LPT-IN is especially recommended for the cure of vinyl ester resins. This MEKP formulation gives less "foaming" than standard MEKP's. Practical experience throughout many years has proven that by the guaranteed low water content and the absence of polar compounds,Butanox® LPT-IN is very suitable in GRP products for e.g. marine applications. The low hydrogen peroxide content of Butanox® LPT-IN makes this peroxide very suitable for the cure of those gelcoats, which tend to microporosity caused by the decomposition of the hydrogen peroxide.
