Product Description
Jinqiang JQ-2118 is a value-priced, solvent-based adhesive tested by Twisted Hobbys for building and repairing EPP models. Its strong, flexible bond performs similarly to other popular flexible hobby adhesives, making it a practical choice for airframe assembly, field repairs, and general RC workshop use.

Flexible EPP Model Adhesive
Primary Material
EPP Foam
Best Use
Assembly and Repairs
A Flexible Bond for EPP Aircraft
JQ-2118 is designed for joints that need to remain flexible with the foam instead of becoming rigid and brittle. The 1.4 oz tube provides a useful amount of adhesive for new builds, routine repairs, and general workshop use.
Recommended Application Method
1
Prepare the joint. Make sure the parts are clean, dry, and test-fitted before applying adhesive.
2
Apply a controlled amount. Spread a thin, even layer across the bonding area and avoid excess adhesive.
3
Align and secure. Position the parts carefully, press the joint together, and hold or tape it in place.
4
Allow the joint to cure. Follow the directions on the product tube and avoid stressing the joint until fully cured.
RC Building and Repair Applications
Airframe Assembly: EPP-to-EPP joints and major structural sections
Repairs: Cracks, splits, tears, and separated EPP components
Hardware: Securing compatible motor mounts, control horns, and reinforcement pieces
Electronics: Mounting servos and securing lightweight equipment where appropriate
Field Repairs: A practical addition to an RC repair kit for flexible foam models
Material Compatibility: JQ-2118 is intended primarily for EPP model construction and repair. Test on scrap material before using it on other foam types, painted surfaces, plastics, or unfamiliar materials.
Application Tip: Flexible adhesives work best when used in a controlled layer. Excess glue adds weight and can extend curing time without improving the finished joint.
Important Safety and Storage: This is a solvent-based adhesive. Use it in a well-ventilated area, wear protective gloves, and keep it away from children, heat, sparks, and open flames. Replace the cap after use and store the tube tightly closed in a cool, dry location.
