Preference between oxime and alkoxy and the more typical acetic cure silicone: Mild to modertley folks can probably choose oxime and be fine ( ASI 388).
Alkoxy ( GE Advanced) smells more rubbery to me and oxime odor is difficult to describe, though it’s very subtle. The choice between alkoxy and oxime would be very individual.Preferences between the two top choices of silicone: Polyether can retain more of a rubber smell even after a few weeks compared to silicone. You can easily have a different preference when it’s wet, compared to a few days and compared to a few weeks. It is possible to prefer polyether caulks (in the sections below) over silicone.Preferences between polyether caulk (like AFM Caulking, Eco-Bond, and Chemlink Clear) and silicone: Though possibly preferable after 18 days of curing. Silco RTV 4500 – acetoxy cure silicone, more typical type for kitchens and bath.Very close second place to lowest odor when wet. GE 2 Advanced – is neutral cure (alkoxy type) for kitchens and bath, and it’s easy to get from the hardware store or Amazon.It says not for use on tub and tile applications, this is because it has no mildewcide.
DuraSil – is nuetral cure (oxime type) without mildewcide, from Green Design Center.
ASI 388 – is neutral cure (oxime type) without a mildewcide from Amazon.Oxime or alkoxy type neutral cure without added mildewcides are the least toxic types of silicone caulking. There is also a small chance you could find an acetic acid cure better after waiting out the cure time, which I would say is 18 days. Which of the two is better (chemically) depends on your specific sensitivities. Oxime silicones have good adhesive strength and suitability on different materials. Neutral cure silicone is the least toxic type of silicone – specifically oxime or alkoxy neutral cure silicones – they offgasses alcohols or methyl ethyl ketoxime, not acetic acid. Silicone is generally for kitchens and bathrooms where you don’t need a paintable surface. But if you are going to be around during the application (or even within two weeks of application for the super-sensitive) be sure to pick the least toxic option.įor most new builds and renos you want one paintable caulk (polyether, below) and one silicone caulk from this list. Silicone caulking is non-toxic and highly tolerable once cured. You can buy this online from Green Design Center. (It retains its rubber-like odor for many months). Paintable: yesĪlternative: ChemLink NovaLink 35 is a similar paintable elastomeric silane-modified polyether but comes in different colors (if that is needed) PSI of 145 Chemlink Durasil in white 3M Marine Adhesive Sealant 4000 also seems very similar (polyether 15-40%, white pigments 35-70%, plasticizer 10-20%, silane 1%), PSI 220-240, and is paintable. It is non-shrinking, zero-VOC once cured. It is polyether resin (90-95%) with amino silane (1-3%) that does not contain solvents (it’s not acrylic, latex, silicone, or polyurethane). It does not hold up as long in the bathroom as silicone with a mildewcide. Around windows, cracks, tub and shower enclosures, backsplash, siding, walls and wood (like sealing molding), and general maintenance. My testing: Not the best when wet, not the best at 24 hours, but the best at one week. It’s used indoors anywhere where it interfaces with a paintable surface and is the non-toxic replacement for acrylic latex caulk.

It can be used around doors and windows and around baseboard and trim. I used this in my bathroom, you can use this around the shower and sink. Upon purchase, I earn a small commission at no extra cost to you.ĪFM Caulk is one of the top choices and is one of two main caulks to have on hand in every build and renovation. This post contains affiliate links to products I recommend. This post covers low VOC, low odor, non-toxic options that are suitable for chemically sensitive or health-conscious folks. For some adhesive types, the one with the lowest VOC level will be the best. In this type of product, a high initial odor/VOC level could offgas faster than one that is lower VOC, and that can be better for the user. I’m interested in the official VOC level and how fast it is to offgas. I’m not interested in certifications like GreenGuard Gold here. I would suggest finding out which are non-toxic and which ones work for you before that urgent repair is needed. You’re going to need them for repairs and renovations too. Testing wood glues, construction adhesives and silicone caulks was the hardest part of building my house since I did this when I was highly sensitive.īut, you’re going to need glues, caulks, and adhesives if you are building so it’s a good idea to start testing them out!
