DCPD blend and VE/ISO/Ortho blend resins.

[sevanseriesta]

I recently ran out of resin, and being land locked I have done numerous searches and looking for providers of resin for a reasonable price. I have failed for the most part, however, I think I may have found someone to help me. However I do believe this resin is different then the resin I have used in the past on this boat. My main questions is

Can I mix using a DCPD blend resin with an VE/ISO/ORTHO blend resin? and I dont mean using a Qt of ISO with a QT of DCPD, I'm saying if I have a cured project that used and ISO blend, can I use a DCPD blend as the second layup of glass? Again assuming that all factors are all the same, area cleaned, acetoned, and grinding if needed.

I am trying to confirm the type of resin that was used to start, but I am almost positive that it was not a DCPD blend.

I don't see why not... But I'm not 100% sure. Read This Your other resin could have been too.
DCPD Resin Grade


You might send a PM to ondarvr He KNOWS Resin. Been in the industry for over 30 yrs.


Is this the resin from PaintsPlus??

Whats the application ?? stringers or ??

No this is not the one from paints plus, I was having to pay for resin and hardner and the price was geting to 175. Thats just to much for me to swallow.

Re: DCPD blend and VE/ISO/Ortho blend resins.

$35 a gallon is a bit high. USC with shipping is about $40. Send a PM to Ondarvr but give him all the scoop on the resin you're asking about. He's a MFG rep and pretty much knows every resin that's mfg in the US and it's properties.

Re: DCPD blend and VE/ISO/Ortho blend resins.

I need to do a little more PB to go under the stringers. They are all in place they just need to to be finished all the way then filleted. Then all of the stringers need to be glassed so pretty much everything but the transom still needs to be done.

Re: DCPD blend and VE/ISO/Ortho blend resins.

This one comes out to $30 a gallon shipped. $100 dollars savings is kinda a big deal for me. Sounds petty I know, but like everyone else that builds there first boat I way under estimated the cost of doing it myself. I thought to myself "PFFT, $2500 to $3500 to redo a boat, yeah right I can do it for Half that" Well that's not the case. And I have 1qt of wasted resin and that's it. I think I have $1750 in it already and I have not even completed the stringers yet. Now I am pretty sure I don't need anymore Glass but well see.

Ill send a message to Ondarvr

Re: DCPD blend and VE/ISO/Ortho blend resins.

Most resins used in production now are a DCPD ORTHO or ISO blend, with possibly a better resin used in the skin on the hull. So the lower cost DCPD blend would most likely be a DCPD/ORTHO resin, which would be normal for putting in stringers. The issue with DCPD is it tends to surface cure much better and faster than ORTHO, ISO or VE, so the time you have before applying the next layup can be shorter, plus it is stiffer, almost brittle. This is why they blend it with other resins, straight DCPD isn't something you would want to use.

Re: DCPD blend and VE/ISO/Ortho blend resins.

Thanks for responding ondarvr, can you tell me when or why they would use a straight DCPD. Also would it be better if I do buy this and it is a straight DCPD, can I use the 2.5 gallons I have left of my other Resin and mix them together or is this a bad idea.

Re: DCPD blend and VE/ISO/Ortho blend resins.

By the way current resin is an ISO blend.

Re: DCPD blend and VE/ISO/Ortho blend resins.

If I remember correctly we used some DCPD/ORTHO blends as a skin coat to block print through. It cures with a higher Barcol and as such it is very brittle and hard compared to an ISO. Some places I worked used it for everything but the better large boat companies used vinylester for the skin coat to help prevent blistering. It should be fine for your purpose.

Re: DCPD blend and VE/ISO/Ortho blend resins.

well after talking to the guy this ends up being an ISO/DCPD blend anyways. Which I believe is the exact same thing that I currently have. So I am pretty happy with the price.

Thanks for responding ondarvr, can you tell me when or why they would use a straight DCPD.

Until the last year or two DCPD resin was much lower in cost than the others, so it was used when cost was an issue and physical properties weren't that important. DCPD was a byproduct of other refining and manufacturing processes, as were some (many) of the other ingredients in most resins, this kept the cost down, some of the raw materials to make resin could be had at very very low cost do to their abundance as a byproduct.

As many refining and manufacturing processes cleaned up their act, and then with the down turn in the economy, the abundance of these byproducts was reduced and the cost went up, which made the cost of all resins increase also. DCPD isn’t that much less than an ISO or an ORTHO now, it went up more than the others.
One benefit of DCPD is that it takes less styrene to thin it down to a usable viscosity, plus it shrinks less than other types of resin, so the surface profile of a part can be better. When the EPA said resin needed to be more friendly to the environment they used the DCPD blends that required less styrene to set the standard (35% styrene). The problem is normal ISO and ORTHO are difficult to work with at 35%, they are sort of thick and snotty, it makes it harder to wet out the glass and roll the air out. This resulted in old school high emission straight ORTHO and ISO resins to be illegal in many applications, and the newer lower styrene versions almost unusable. The dependence on DCPD to meet the 35% styrene limit could cause problems if the cost of it continues to climb as the supply is reduced because there really isn’t a good and legal alternative.

Wow.. my cost is 30 something a VE QT .. and I have to pick it up

Re: DCPD blend and VE/ISO/Ortho blend resins.

It was my understanding that VE is a higher quality, is that not true?
