Shedding sandpaper?…I’ll call it

Is there a brand of sandpaper that’s known for not clogging up? Ideally available in sheets. I’m about to be sanding a resin project up to 600 grit and I can see going through some sandpaper if it clogs up easily on this resin. I’ll be chilling the piece before sanding to try to combat any heat buildup. Thanks.

I like 3m paper or Norton. I've used Festool paper, actually they gave me a bunch once ( and a hat ) as a promotion and I found it to be just sandpaper all and all. A paint store near me is pushing it so I sometimes buy it 'cause I'm there. The short answer to your question is - No! They all clog up. I find that any good quality paper will cut longer than the cheap stuff. I bought some Harbor Freight paper once. That is what I mean by the " cheap stuff". Scrapers are good,they don't clog up!
There's resin and there's resin - some are prone to melt amd clog sandpaper much more than are others. Which are you having to sand?
When a melt-clog is probable, it can help to hand-sand as this generates less heat and thus less melt&clog. But if you have a lot to sand .....
One of the rubberised sticks used to unclog machine sanding belts, discs and the like can sometimes pull off resin-clog; but it depends on the nature of the resin. Some are tenacious, very sticky and unwilling to leave the sandpaper. Others come away easily on the rubber stick.
You can also try sanding the clogged sandpaper with another, rougher-grit, piece of sandpaper. Sometime a splash of denatured alcohol or similar will help loosen the resin-clog.
But Mr 868 is right. If whatever you're sanding is amenable, use a scraper.
