looks like lbr-1370 is 70 degree (fast) and lbr-1380 is 80 degree (slow).
the tech sheet for the base should say the temp range.

Well I grabbed some PPG epoxy primer a couple of weeks back, I just looked and noticed they'd sold me the fast hardner and fast reducer .... I read the spec sheets.... Suitable for temperutures upto 18 ..... er .... where's there google converter ..... 64degrees... How will this handle higher temperature, the average temperature here will soon be... (**** where's that google window again) 75-85degrees during the day. Should I return the reducer and hardener and swap it for some medium, or possibly slow ??
As I'm doing only one panel at a time should the fast primer and reducer still be ok at warmer temperatures seeya, Shane L. The nutty Citroen guy...

You said "Suitable for temperutures up to 64?
They always told us not to spray under 65 degrees. Is it different for epoxy??? |

Hmm,
here we go: Product: PPG Epoxy Urethane Primer. 410-48248 Temperature. Up to 18C (64f) D803 MS Fast hardener hardener, D870 fast reducer. 18-25 (64 - 77f) Hardener medium (D841), reducer medium(D871) 25-35 (77 - 95f) Slow hardener (D861), reducer slow (D872) Over 35 ( 95f) slow herdener (D861), very slow reducer (D873). Pot life: D803: 25mins at 25 (77f) D841: 40mins at 25 (77f) D861: 2hours at 25 (77f) Oh gee's, I really am going to have to return the reducer and hardener, medium would probably be a good comprimise if I don't want the stuff setting in the pot I have the Delton Fast reducer and Deltron fast hardener. seeya, Shane L. The nutty Citroen guy...

yea mike, I'm using limco supreme. I looked over the same tech sheet you posted and all it mentions was the p# for the reducer and whether it was slow or fast. I have a good deal of slow reducer left and would like the use that up if at all possible so if temps are in the 75-80 degree range I should be ok? Any thoughts on the coolest temp to spray a slow reducer...low 70's? |

I have the same question but only concerning clearcoats.
what is the difference between fast , med , slow hardener . I plan on using Tamcos 30 min hi impact clear to cover artwork . The kit from coastairbrush ( where I get all my stuff from) offers it with only one hardener the medium. I'd just like to know what the difference is. Thank you to all that reply. |
Man, been a while since I have been logged in here!
Looks like that clear is a speed clear, designed to kick and harden quickly. Typically the hardener will correspond with the temperature that you will be painting in. A slow hardener (and reducer) is suitable for higher temperatures (80'-90's) or where you have time for it to flow out. A medium is mid-range around 75 or so, and fast is for colder temperatures to help speed it up. These temp ranges vary from product to product For this clear it looks like the medium would be used in most cases for it to kick off properly and be buffable in under an hour (other things like time to 'dust free' are likely more important in this use case). https://tamcopaint.com/products/hc9500- ... -clearcoat Looks like slow is not an option, as it would defeat the purpose of the speed properties of this clear. NOTE: WE removed the option for slow hardener. HH7607 Slow is far to slow for a 30 min clearcoat. Call the tech department with any tech questions. We do not recommend it, so it is not an option. same information applies for slow and ex slow reducer. |

I use the slow reducer in most everything all year long.
I also prefer to paint when it's raining, I get cleaner paint that way. ( not to do when spraying lacquer, which I don't use anymore) JC.

What Paint system are you using? Its possible your dealer may not stock all that's available for a particular line and may have to order it. I have a few dealers like this, It always makes the one clerk angry when I request stuff he doesn't stock but he can get. He says "Your always Ordering weird s it!" I do my home work I don't trust some Kid behind the sales counter to get my advise or suggest products from! AND OP Great job doing your own research and digging up an Old thread that you needed info on to clear up your questions!!!!! I personally would like to see more old threads get pulled up and commented on too continue the conversations than too start a new thread or threads Muddying the waters. Dennis B.
