STYPOL® 040-8003 must be mixed prior to use. Ingredients in the STYPOL® 040-8003 will settle during storage. Failure to thoroughly reincorporate these ingredients will compromise the flame-retardant properties of the end product. Use mixing equipment with sufficient horsepower (relative to container size) to achieve thorough circulation from top to bottom and out to the sides of the container. The agitator must be properly sized for the container and must allow for uniform mixing regardless of the liquid level in the container. Scrape the bottom of the container to ensure that all ingredients are being pulled into the mix. After settled materials have been reincorporated, mixing once a day for 10 minutes is typically sufficient.
Air bubbling should not be used for mixing. It is not effective and only serves as a potential source of water or oil contamination. Do not overmix STYPOL® 040-8003. Overmixing can break down the resin viscosity increasing the tendency to sag.
The cure rate of polyester resins depends on a number of factors including the product’s age, temperature, catalyst type, catalyst level and ambient humidity. When used in a laminating application the laminate cure rate also depends on reinforcement content and laminate thickness as well as other factors. For these reasons, we recommend that customers check the cure rate in their plant.
STYPOL® 040-8003 is quality control tested using United Initiators Norox® AZOX (acetyl acetone peroxide or AAP). Arkema Luperox 224 is expected to give equivalent results.The catalyst level should not exceed 2.4% or fall below 0.9% for proper cure. A catalyst level of 1.25% at 77°F is considered ideal.This product should not be used when temperature conditions are below 60°F, as curing may be adversely affected.
