Vinyl Resin Construction Advice
Curing System Selection
Standard MEKP with Cobalt octoate suggested for optimal gel time at 15-30℃.
Post-Curing Treatment
Post-curing at 80-100℃ for 2-4 hours is recommended for ultimate heat resistance.
Storage Conditions
Highly stable but store below 25℃ in a ventilated area to maintain shelf life.
