Beatnik cryptek Posted July 20, 2019 Share Posted July 20, 2019 OK, >serious≤ question here brothers: I'm getting ready to get cracking on my first resin kit. It's Chinese resin, Grey, lightweight and really feels like plastic. Now I've heard horror stories about the dangerous of working with resin, like resin dust dust messing up your lungs, mucous membranes and eyes. Tell me the truth from your own experiences, my brothers. Do I need to wear a filter mask and eye goggles to work with a resin kit? Should I have a fan blowing across me to blow resin particles away with I clean up some spots by shaving them with an xacto knife? That's mostly what this kit needs, some trimming and shaving with a nice fresh xacto knife blade. Maybe a little hot water applied to a spot or two to bend it back into shape. So, breath mask and goggles? Or do I need to go full money and on my darth Vader mask?

Gederas Posted July 20, 2019 Share Posted July 20, 2019 Honestly, because it's Chinacast: YES! Because you don't know what stuff was used in it. I've never needed to use a mask when doing standard work on my resin kits (GW and Forge World), only time I break out the mask and goggles is when I need to use a dremel to carve out large portions.

armarnis Posted July 20, 2019 Share Posted July 20, 2019 Depends on your seller, china banned toxic resins so even Z should have environment friendly non toxic material, people like MI, PW and CCON are fine. If you file or sand your stuff you should wear a mask no matter what though as the fine particles can be breathed in but that goes for everything and is not a resin specific thing imho Link to comment https://bolterandchainsword.com/topic/357256-is-resin-dangerous-to-work-with/#findComment-5349971 Share on other sites More sharing options...
Brother-Chaplain Kage Posted July 20, 2019 Share Posted July 20, 2019 When working with resin, I use the 3M 6001 respirator mask I bought at a paint store some years ago. Those cheap little paper mask with a rubber band you buy in bulk? They don't do much at all for fine particulates from resin. If you're ever going to use a file or sandpaper on resin, always do it wet so less particles get into the air. When you're done, empty the water container and rinse it several times - don't let it sit on your desk until the water evaporates.

Captain Antargo Posted July 20, 2019 Share Posted July 20, 2019 I have never used it and don't plan to as it can be quite fragile and isn't that strong. And that is why I am waiting for a plastic version of Dante. Although it is quite damage resistant!

Arkhanist Posted July 20, 2019 Share Posted July 20, 2019 First up - most warnings about resins are for industrial scale applications for substantial exposure, rather than simple hobbyist scenarios where you're working with one kit for a few hours then done. So bear that in mind when it comes to some of the more lurid toxic warnings. The main issue really is fine dust is a lung and eye irritant, regardless of source, and that will depend upon how sensitive you are as an individual, and how much dust you generate. Carving with a knife will generate very few airborne dust particles, using a dremel sander will kick up quite a lot! Some people get skin irritation even from forgeworld resin - if you're one of those people, wear disposable nitrile gloves or the like. Anyway, if it's just shaving with a knife you probably don't need anything at all, though a basic N95 dust mask will give you peace of mind. Once you get into significant sanding with a file, or more so with anything powered, I'd definitely want at least a n95 mask, and probably a N99. The full or half-face filter cartridge masks are there to block airborne organic solvents from oil paints etc, which are far smaller than even micro dust particules, but they do have a better face-mask seal which helps prevent dust ingress. If you do end up using a powered tool, I'd definitely consider eye protection as a good idea - flying bits as well as dust! Wet-sanding is a good idea for the lifetime of the sander surface, and helps keep down airborne particles, so I'd definitely wet the surface (I have a little perfume mister filled with water which does this job perfectly) for any sanding at all - and wipe down your worksuface of any leftover dust with a wet rag/paper towel afterwards. I do this even with plastic, cos it keeps my tools working better for longer.

SickSix Posted July 23, 2019 Share Posted July 23, 2019 If sanding or doing anything that creates fine particulate definitely wear a respirator not a cheap dust mask as has been mentioned.

Arkhanist Posted July 23, 2019 Share Posted July 23, 2019 If sanding or doing anything that creates fine particulate definitely wear a respirator not a cheap dust mask as has been mentioned. Depends upon the respirator filters - one with cartridges designed for only organic vapour (such as acetone) can often be worse than a basic disposable N95-rated or equivalent dust mask - they're not rated for particulates. A respirator with organic and particulate filters and/or combined into a single larger cartridge will cover you for both types of hazard, but of course will be bigger and bulkier. Resin dust doesn't contain oil particles so we can ignore R and P ratings for this purpose. N-rating goes from N95 to N100 - they will block 95%, 99% or 99.97% respectively of PM2.5 which will catch airborne epoxy resin particles - one with an exhaust valve or two will be more comfortable for longer. The advantage of a respirator is they tend to have a better face seal that the dirt cheap masks (along with better straps and valves) but the trade off is cost, weight and if it's too darth-vadery you won't use it as much as you should. I have a lightweight N99-rated mask (the sort of mask urban cyclists wear) that I use for sanding inc. resin, and a half-mask respirator with combo cartridges that's primarily for oil and organic vapour with some particulate protection - for larger particle sizes e.g. dust, the N99 mask is actually better protection, but is pretty much useless when I'm spraying oil/organic solvents through the airbrush, which is why I have the respirator as well.

Lucifer216 Posted July 31, 2019 Share Posted July 31, 2019 I can vouch for the wisdom of using suitable protection. I put together a FW knight without a mask a year or two ago and my lungs didn't feel right for weeks afterward. It wasn't horrible, but they did feel irritated. The same thing happened when I bought a couple of big kits on eBay and found that they were recast, despite me being a lot more careful and wearing a mask for all the but shortest of hobby sessions. I should add that I didn't do any sanding and just used a modelling knife and clippers. One related issue I encountered was that because I was so paranoid about the resin dust, I hoovered during the project – which was a mistake as I ended up having to rescue a shoulder piston from a rubbish bag.
