A) Chemical
B) Specific

Question 19

Cyanoacrylate is inexpensive and is good for large gluing jobs.

Question 20

Surfaces to be bonded should be glued as soon as possible after machining is complete.

Question 21

____ adhesives come in a solid form, usually a stick, and are applied with a special applicator, often called a glue gun.

A) Hot-melt
B) Spray
C) Spread
D) Contact
