|
Uses : |
|
As a "Catalyst" or "Accelerator" which acts as an end-to-end linking agent.
|
|
|
|
For better penetration and stability BDMA is recommended in place of the DMP-30. |
|
The quantity of BDMA which is required is 1-1.2 ml.Slight variations of the accelerator (DMP-30 or BDMA) will drastically affect the color and brittleness of the block. |
|
It is desirable that only the minimum amount of accelerator (BDMA) be used, and should be added just prior to actual use of the resin mixture. A plastic mixture to which accelerator has been added cannot be kept unrefrigerated for more than several hours before it begins to polymerize. |

Health Hazard Information : |
|
Eye Severe eye irritant. Vapours are highly irritating to eyes. Liquid may cause permanent eye damage.
|
|
Skin Severe skin irritant. Vapours are highly irritating to skin. Skin exposure to laboratory rabbits produced tremors and excitement.
|
|
IInhaled Vapours are highly irritating to lungs and upper respiratory tract. |
|
Chronic Conjunctivitis in the eyes can result from overexposure. Dermatitis of the skin can result from overexposure. |
