Please see the 4th point in this em

Please see the 4th point in this email. It is regarding the varying of density. In the last Email I couldn't mention a point. Thanks you. Equipments seems nice. I have an email from uretek I will forward it to you. It is about the varying of density with ratio. Hope it will be useful. And about mixing, as from uretek we can't just inject the chemicals expecting them to mix inside. They said that we have to use the gx 7 spray gun or we will have to shake the mold very well or they won't mix it properly. According to them if we do so it will reduce its original strength by 80%. I my self did a small research about the gun. Even if we find a method to mix them I couldn't come up with a solution to exert the pressure like the gun. I wanted to talk about that matter with Dr. Seah. But he couldn't come to ait last time. Any how this is my idea and news from uretek. I will forward the email from them to you shortly. And please let me know if my attendance or help is required I am so glad to come down there
Thank you!
