- Spatter Cure SC-07, an anti - spatter compound cum flux
will be very useful to improve the welding performance.
M/s. Welding Research Institute, (Trichi) , INDIA.
- We have tested the sample of your product SC-07
with manual metal arc welding and CO2 welding. The results
are found satisfactory.
M/s. Bharat Heavy Electrical Ltd.,NOIDA, INDIA.
- An innovative product developed by M/s. Spatter Cure Enterprises,
New Delhi, reduces the requirement of chipping and grinding
between inner layer welding. The product was tried at our
IP-WHRP site where it has given encouraging result.
M/s. Engineers (India) Ltd.,INDIA.
- We opine that this product would be of use at any of our
vender/contractors works/site.
Lloyd's Register Industrial Services (India) Pvt. Ltd.,INDIA.
- We don't have
any objection to the use of the product provided the users
have qualified their welding procedures using this product
and the guidelines for its use are adequately addressed.

It is imperative for them
to maintain the work place clean and for that they are to
sacrifice a number process/products which are not environment
friendly. In this circumstances the use of SPATTER CURE SC-07
helps them avoid a precarious situation because its anti spatter
compound characteristic.
It is advantageous since the absence of chipping and grinding
operation improves the environment of the working place reducing
the noice as well as dust pollution as shown under:-

As is evident,
it reduced the SPM (Solid Particulate Matter) concentration
in the working place from as high as 1200mg/Cu m to below
150mg/Cu m; though the recomended level is 250mg/Cu m. To
maintain the health standerd in a workshop and to improve
the environment in the working place, WHO has stipulated a
certain level (as shown above) beyond which it creates health
hazards.
