Inquiry (采购产品): materials Good day. I have two possible polyurethane applications to solve a manufacturing problem: I currently mold a bladder made out of silicone. This bladder must be impermeable to water and is not.Its made with very elastic 40 duro liquid silicone. Solutions: Can I coat the silicone bladder with polyurethane to make it waterproof? or, do you have a polyurethane injection moldable grade of about 40 durometer Shore A and high elesticity? PLease send me a reply ASAP. Thank you Fernando Suarez Eng. Magr. Sorrento Inc. (949)374-3784 **** Hidden Message ***** Fernando Suarez 13417 Benson Ave Chino, CA 91710 USA Company: Sorrento Inc.
