Which Adhesive Should I Use?

Disclaimer: Always read the manufacturer's Technical Data Sheet before specifying an adhesive. This tool is for guidance only and may contain errors.

Substrates

Substrate A Substrate B

Pick the two materials being joined. Products are ranked by the minimum lap shear on either substrate.

Service temperature

Coldest (°C) Hottest (°C)

Products must have service_temp_min ≤ coldest AND service_temp_max ≥ hottest.

Primary stress mode

Shear (default) Peel — reweight by peel strength Impact — reweight by impact energy

Viscosity

Leave all unchecked to match any viscosity.

Wicking (< 500 cP) — capillary / pre-assembled Low (500 – 5,000 cP) — liquids, CAs Medium (5,000 – 50,000 cP) — most structurals High (50,000 – 200,000 cP) — pastes, FIPG Very high (> 200,000 cP) — thick pastes

Thixotropic / non-sag only (vertical surfaces)

Service environment

Flags products with <50% retention at 1000 hr as warnings. Check ⚠ Exclude to hide them.

Humid / outdoor exposure Fuel / oil exposure Water / coolant immersion ⚠ Exclude flagged products

Process constraints

Min pot life (min) Max fixture time (min) Cure mechanism Min gap fill (mm)

Thermal & Optical

Min thermal conductivity (W/m·K)

Only products with TDS data; 27 of 135 have values.

Require optical clarity (leave all unchecked for any):

Optically clear Transparent Translucent
