Test methods (peel test, pull-off test)

Test methods like the peel test and pull-off test are used to evaluate how well materials stick together. The peel test involves slowly peeling two bonded materials apart, measuring the force needed to separate them, which indicates adhesion strength. The pull-off test involves attaching a special device to a coated or bonded surface and pulling straight away from it, measuring the force required to detach it, which assesses adhesion or coating durability. Both tests help determine if the bonding is strong enough for practical use, ensuring safety and reliability in products and structures.
