has anyone used ver from composites one? what brand and product number do they sell? I want to look up the specs but it’s not on their cd=rom.
I only used ArmorStar IVEXC400 from CompositeOne made by CCP.

The smallest qty you can order it in is a 5 gallon pail.
Very cool… low exotherm infusion vinyl ester.
I may have to give that a try some day.
I have composites one vinylester but i don’t know which one… my supplier repackages it… but I think it may be that high performance blend vinyl ester resin… non infusion type. The stuff is viscous.
I am learning differnet types and brands of mekp can slow down or speed up the cure. I just didn’t know different VER could do the same. It’s crazy fun and good how many choices we have in resin and catalysts from all these companies.
316composites, if you don’t mind me asking how much do they sell a 5 gal pail for?
4.024 per pound and 5 gallon pail (40 pounds) so about 161.00 before shipping.
I know that changing the MEKP amount will change cure times, along with varying amounts of Cobalt, 2,4-P, and DMA. To be honest, I have only used Derakane’s VER (510, 8084 and 530-411), and only with MEKP, although many here use Triginox instead. The website has a cure chart of 3-4 different room temps, and cure times. I can modify the recipe from 10min to 2hr if needed, just by changing the amounts of stuff. Epoxy around here though…you just mix and wait :-/ No fast/slow hardeners.
I need to correct that. Many popular epoxy systems have ranges of hardeners with different curing speeds.
With polyester and VE resins, it is both the resin, the accelerators and the curing agent that determines speed. Accelerators and curing agent usually are known and common, but if I add exactly the same amount of accelerator and curing agent to 2 different polyester resins, the curing speed can differ dramatically.
accellerator? is this a third part that can be added?
why not just add more mekp instead of accellerator? What does the accellerator prevent or do?
they are talking about unpromoted resin systems.
It is good practise to keep “catalyst” (peroxide) levels between an acceptable level. (some 1,5 - 2,5 percent).
Any lower, and you run the risk of undercure. Surprisingly, any more, and you run the risk of undercure as well. The peroxide creates a radical, (a molecule that almost immediately wants to bond woth other molecules). If, due to too much peroxide, a large number of radicals is formed, they react with each other, effectivly stopping their activity. All you are left with is the pflegmatiser which diluted the peroxide.
