Q
how much wax to add to polyester resin
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
When adding wax to polyester resin, the standard ratio is about 2% wax by weight to the resin before adding any catalyst. This wax, often referred to as surfacing agent or sanding aid, rises to the top of the resin as it cures, forming an air-inhibition layer. This crucial layer prevents the resin's surface from remaining tacky, allowing it to fully cure and be sanded or further worked upon. It's essential to accurately measure the wax-to-resin ratio to ensure optimal curing and finish of the polyester resin project. Depending on the specific project requirements or environmental conditions, slight adjustments to the wax ratio may be needed.
