Inhibitor DD-10
* Incl. VAT excl. Shipping
Inhibitor DD-10 is a 10% retarder concentrate.
Adding this retarder to your polyester resin can extend the working time significantly without affecting the curing time. Adding 0.2% roughly doubles the working time. When 0.5% is added, the working time is approximately quadrupled. These figures may vary depending on the reactivity of the resin types used and should always be determined in advance through your own tests!
