What adhesive, buck converter heatsink?

[acropolis22]

Instructions a bit light in the pack......... How do I stick down the heatshield on this baby? Lenny HB maybe?

Very thin, white, under the heatsink? I thought that was just the colour of the sink...... Cheers.

BTW, why is it called a buck converter?

Buck, it’s when it cuts, it takes a higher voltage, cuts it and convert it into a lower voltage. Ex 18v 1a in 13v 1,38a out. The power stays the same but voltage differs.
A Buck Boost converter can do both cut or boost the oncoming voltage. A B2B charger has buck converter. A Orion converter has buck boost. A mppt solar has buck, a wind turbine mppt has buck boost.

Yeah, thanks. I know what it does. Just wondered why Buck? Is that a brand name or am I missing something obvious?

I just explained in my first sentence, it’s a function. Not a brand or name.

Log bucking is when you cut trees into smaller logs

I stuck a heatsink on a 8 pin DIP chip about a year ago with superglue gel, it's upside down and still on it

Well, you learn something new every day. Never heard that before. Makes sense now someone has spelled it out.
