Is Gorilla Hot Glue the Best? Let's find out!
Is There a Difference in Hot Glue Sticks?
Overview of Testing Methodology
- The video explores the differences between various hot glue stick brands, focusing on price and durability claims.
- Three tests are conducted: measuring shear strength with two by fours, tensile strength with one by twos, and tensile strength using PVC end caps.
- A jig ensures accurate drilling for test samples; painters tape is used to prevent glue from sticking to the sides of the wood during testing.
- Each brand's glue is applied at a 100-watt setting after a 15-minute warm-up period, ensuring consistency across tests.
Shear Strength Test Setup
- For the shear strength test, two by fours are arranged in a T-shape; tape prevents glue from adhering to unintended surfaces.
- Deck screws secure the pieces while the glue cures; these screws will be removed before testing to measure true shear strength.
Brand Comparisons and Claims
- Tenet claims their pro-strength glue stick bonds well with wood, metal, glass, and plastics.
- Arrow brand offers an all-purpose multi-temp glue stick suitable for crafts and repairs. Elmer's promotes reduced stringing due to advanced technology.
- Gorilla hot glue sticks claim five times more durability for various materials. Stanley’s dual-temperature sticks are marketed as all-purpose.
Tensile Strength Testing Process
- The next phase involves attaching pipes to PVC ends for tensile strength evaluation.
Results of Shear Strength Test
- Sure Bonder leads with 1523 pounds of shear force strength; Stanley follows closely at 1503 pounds—more than two 16-penny nails combined.
Results of Tensile Strength Test
- Float emerges as the top performer in tensile strength with 800 pounds; Stanley ranks second but shows strong performance overall.
Summary of Findings
- Stanley consistently performs well across tests, averaging first or second place in categories evaluated.
- Surprisingly, lower-priced products like Stanley outperform higher-priced competitors in multiple categories.
