Line 3 on the above PO is requesting a blend of 4,000cps at 140°c. That temperature, 140°c, is too hot for our blends.
A suggestion would be for you to purchase the HT30000 high temperature silicone which has a nominal viscosity of 4,500cps and temp of 149°c.
Please advise if you would like to purchase the HT30000 and send me the revised PO to reflect same or advise me of your other intentions.
