Industrial and STP
Silyl-terminated polymer sealant for metal, plastic and glass — primerless and paintable.
Choosing one
Choose STP for exterior panel joints and mixed substrates, not for structural load. KAM921 is UV-stable, paintable and primerless on most metals at 1.8 MPa and Shore A 40, which is roughly half the tensile of a glazing PU. If the joint carries load, this is the wrong family.
Send the substrate, joint width and UV exposure and we will confirm whether STP or PU is the right family. ryan@pu-karmind.net
Other families
- Automotive glass bonding — Windscreen, side and rear glass adhesives — 310 ml cartridges, sausages and 200 L barrels.
- Body and sheet metal — Seam sealers for body panels, doors and container joints — sandable, paintable, four colours.
- Construction joints — Concrete, tunnel and drainage sealants — 550–615% elongation, elastic recovery up to 80%.
- Wood and glulam — One-component PUR for engineered timber, glulam beams and sandwich panels.
- Activators and primers — Surface preparation that decides whether the bead holds: K-901 activator, K-801 primer.
