Product Description
JS-335 is a two-component polyurethane structural adhesive with an angle structure. It is suitable for structural bonding and sealing of materials such as wood, plastic preforms, metal fasteners, adjustment parts, glass steel, aluminum plates, steel plates, etc. It has a fast curing speed, high bonding strength, good weather resistance, and does not contain volatile solvents. It is environmentally friendly.
Product Applications
Structural bonding and sealing at the corners of insulated aluminum alloy doors and windows;
Structural bonding and sealing at the corners of steel-plastic extruded profiles and wood-aluminum composite doors and windows; Structural bonding and sealing for metal curtain wall doors and windows;
Structural bonding and sealing for ordinary aluminum alloy doors and windows and wood-aluminum doors;
Bonding of aluminum materials inside and outside the camper;
Bonding of polyester components and metal frames;
Structural bonding for other materials.
Product features
Excellent thixotropic property, anti-splashing;
Excellent adhesion to the substrate;
Good heat resistance and weather resistance;
Fast curing speed;
The curing process does not rely on moisture and no irritating gases are produced.
Usage instructions
Clean the surface of the substrate before use to ensure there are no dust, oil stains or other debris.
Usage method 1 (Bucket type):
1. Mix the A and B components in a 1:1 ratio and pour or squeeze them into a suitable container.
2. Use a suitable equipment (electric mixer or ordinary stick-like object) to stir evenly.
3. Apply it to the area to be bonded using scraping or other methods.
Usage method 2 (AB tube):
1. Put the tube into a manual or pneumatic two-component glue gun;
2. Remove the block at the front end of the tube, screw on the spiral extrusion-type glue nozzle, and cut the size of the glue nozzle outlet as needed;
3. Start the glue gun, squeeze out about 20g to discard, then apply it to the area where the substrate needs to be bonded or sealed.
Residual glue cleaning method
General industrial cleaning solvents are applicable for residual glue removal.

FAQ
FAQ 1 What is JS‑335 Two-component Polyurethane Angle Adhesive
JS‑335 Two-component Polyurethane Angle Adhesive is a two-part polyurethane adhesive composed of Component A curing agent and Component B polyol. It is professionally formulated for angle joint bonding of aluminum alloy doors, windows and curtain wall profiles. Users need to mix the two components evenly before construction, and the mixture will form high-strength structural bonding after curing.
FAQ 2 What are the suitable construction and service temperature for JS‑335 Two-component Polyurethane Angle Adhesive
The proper construction temperature ranges from 5℃ to 40℃. After complete curing, JS‑335 Two-component Polyurethane Angle Adhesive can maintain stable performance under -20℃ to +80℃, adapting to diverse outdoor climate conditions of door and window projects worldwide.
FAQ 3 What mechanical performance can I get from cured JS‑335 Two-component Polyurethane Angle Adhesive
The cured JS‑335 Two-component Polyurethane Angle Adhesive achieves shear strength higher than 8.0 MPa and shore hardness above 70. It has a sagging value of zero and will not drip or run on vertical profile joints to keep neat glue lines during mass production. Outstanding mechanical strength provides solid structural reinforcement for spliced corners.
FAQ 4 What operation and storage tips should I follow for JS‑335 Two-component Polyurethane Angle Adhesive
The usable pot life after mixing A and B components is 20–30 minutes, please finish application within this period. Keep unopened packages in cool, dry and ventilated environments with storage temperature below 30℃, stay away from direct sunlight and high heat. Using the product before expiry can secure stable bonding performance.
