7. FAQ
What is a two-component polyurethane structural adhesive?
Two-component polyurethane structural adhesive is a kind of adhesive composed of two components (usually resin and curing agent) mixed in a certain proportion and cured by chemical reaction to form a tough structure. It has high strength, weather resistance and excellent elasticity, and is widely used in structural bonding in construction, automobile and other industries.
What are the advantages of two-component polyurethane structural adhesive?
High strength: The adhesive layer formed after curing has extremely high bonding strength.
Weather resistance: can withstand extreme weather conditions, not easy to age.
Good elasticity: It can still maintain good bonding performance under temperature difference.
Excellent chemical resistance: shows good tolerance to a variety of chemicals.
How to correctly use two-component polyurethane structural adhesive for window and door corner bonding?
Surface treatment: Ensure that the adhesive surface is clean and free of oil and dust.
Ratio mixing: According to the product instructions, the resin and curing agent are accurately proportioning, and are fully mixed evenly.
Sizing: Apply the mixed glue to the bonding part to quickly complete the positioning.
Curing time: Keep at rest and wait for the glue to cure completely before it can be put into use.
What are the effects of an inaccurate mix?
Inaccurate mixing ratio can lead to incomplete curing or over-curing, affecting bond strength and durability. You are advised to strictly follow the product instructions.
In what environments can two-component polyurethane structural adhesives be used?
Suitable for indoor and outdoor environments, including wet, high and low temperature conditions. However, it is necessary to avoid direct exposure to strong acids and alkalis.
Can two-component polyurethane structural adhesives be used to bond other materials?
In addition to the corner bonding of doors and Windows, it can also be used for structural bonding of metal, plastic, wood and other materials, but it is necessary to choose the appropriate product model according to the specific material.
How to remove excess two-component polyurethane structural adhesive?
Excess glue can be removed with a scraper or a solvent (such as acetone) before the glue is cured. Once cured, it needs to be removed by mechanical methods.
Why choose a two-component polyurethane structural adhesive instead of a single-component silicone or other type of adhesive?
Compared to single-component silicone or other adhesives, two-component polyurethane structural adhesives perform better in terms of bond strength, weather resistance and elasticity, especially for structural bonding applications that withstand greater external forces and harsh environments.
Can I use a two-component polyurethane structural adhesive on a vertical surface?
Yes, but make sure the glue doesn't run down before curing. Tape or other support materials can be used to secure the position.
