VA 250 Black High Viscosity, High Heat Rubber Filled Super Glue 30gm Pen

• A specialised type of super glue that is black in colour as it is rubber filled.
• This rubber filling enables VA 250 to provide good residual elasticity after curing and makes it particularly suitable for use in high or rapidly changing humidity.
• Higher viscosity (less runny) grade of super glue with excellent heat resistance (140°C).

VA 250 Black is a professional-quality super glue that has been developed to meet the needs of industrial applications. This specialised glue works with a wide selection of materials and creates high strength bonds with high peel and impact strength.

Where VA 250 really shines is in its suitability for specialised applications. Like our VA 30 Black, VA 250 is a rubber-filled super glue which gives it its black colouring. The rubber is for much more than aesthetics, it also helps give this glue excellent residual elasticity and humidity resistance.

The sections below expand on the various features and capabilities of this professional quality super glue. 

Residual Elasticity & Resistant to Vibration and Humidity.

The black, rubber filling used for our VA 250 Glue increases its' residual elasticity. This allows it to absorb a little more joint movement than most super glues while still maintaining high bond strength. 

It also increases this glue's capacity to withstand changing climatic conditions and high humditity (which can be an issue for some super glues over time). 

High Viscosity Glue.

VA 250 Cyanoacrylate has a viscosity of 2.000 - 3.000 mPa·s (at 20°C according to Brookfield). We classify this as a high viscosity which means this glue is quite thick and able to be applied very accurately. This thicker nature also slows donw the cure time a bit and allows VA 250 to cover slightly larger bonding gaps than some super glues (up to 0.2mm).

Slower Cure.

VA 250 Super Glue has an extended cure time. Like most glues, cure time for VA 250 will vary depending on materials and the conditions you are bonding in. Maximum cure time will be around 120 seconds (bonding aluminium in a cool area with low humidity). Usually it will be closer to 40-90 seconds depending on the materials and environment. 

High Peel and Impact Strength.

Another benefit of the rubber filled nature of VA 250 manifests in its' increased shock and impact resistance. Bonds made with VA 250 Glue will absorb more impact than many other glues and maintain their bond strength. This glue also has high peel resistance.

Temperature & Environmental Resistance.

Once fully cured, Our Weicon VA 250 Glue will withstand continuous exposure to temperatures between -55°C and +140°C. 

Squatting temperature is +160°C.

VA 250 Material Compatibility.

VA 250 Black Super Glue is most commonly used for gluing rubber parts (including solid and sponge rubber). It is also used with many types of plastics and metals. As the table below suggests, this glue is compatible with most material types.

Applications for VA 250 Black Super Glue.

• Bonding of different rubber materials such as Neoprene, Natural, Nitrile.
• Making high strength rubber O Rings from rubber O Ring Cord.
• Securing rubber sponge and foam.
• Making metal to plastic and plastic to plastic joins.
• Bonding leather and other slightly porous materials.
• Creating high temperature resistant bonds.
• Bonding and gluing for applications that require good humidity resistance.
