How to say "adhesive" in Japanese

• 接着剤せっちゃくざい
  nounThe general term for an adhesive or glue as a substance — the word you see on packaging and in instructions for bonding materials together; for plain 'glue', start here.

  This fluid can be substituted for glue.
• 粘着剤ねんちゃくざい
  nounCovers pressure-sensitive adhesives — the tacky kind that grips under light pressure and can be peeled off, as on tape or labels — rather than glue that sets into a permanent bond.
• 接合剤せつごうざい
  nounA less common term for an adhesive that joins parts or surfaces together; for ordinary glue, 接着剤 is the word you will usually want, so this one is seldom necessary.
• セメダイン
  nounReally a brand name — that of a well-known Japanese adhesive maker — used loosely to mean glue; it is not a neutral generic word, so avoid it in careful writing.
• 糊剤こざい
  nounA technical term for pasty preparations: it can denote a paste-type adhesive, but it also covers salves and similar products, so it is seldom the word you want for plain glue.

Choose 接着剤 for glue or adhesive in general and 粘着剤 for pressure-sensitive, peelable adhesives; 接合剤 is a less common joining term, 「セメダイン」 a brand name, and 糊剤 a technical word for pasty preparations.
