Color
Saiqiang 999 neutral silicone structural adhesive is available in standard colors: Black, White, and Clear. Other colors can also be provided according to customer needs.
Storage and Expiry Date
🗄
Saiqiang 999 neutral silicone structural adhesive is stored in its original packaging under dry and ventilated temperature conditions of 27℃ or lower, with a storage period of 12 months.
Technical Data of Material Properties
Saiqiang 999 neutral silicone structural adhesive can maintain good viscosity under environmental conditions of -25~50℃, making it easy to extrude and use. It maintains good elasticity at -50~150℃ after curing.
It is not affected by sunlight UV, rainwater, ice and snow, air pollution, ozone, and high and low temperatures. Even when exposed to adverse weather conditions, it still maintains excellent weather resistance, waterproof and sealing performance after several years.
Saiqiang 999 neutral silicone structural adhesive is compatible with reflective glass, laminated glass, silicone insulated glass, acrylic acid, polyethylene, and other materials.
Applications
- ◆ The new molecular structure colloid is smooth, fine and non-porous.
- ◆ The texture is fine, without impurities and pores, and the glue is smooth.
- ◆ The full bonding solution is widely used.
- ◆ Suitable for sealing all kinds of doors and windows, glass curtain walls, stone curtain walls, aluminum-plastic panels, ceramic glass.
- ◆ Can also be used for bonding the same or different materials such as metals, ceramics, plastics, rubber, and wood. It can partially replace traditional connection forms such as welding, riveting, and bolting. The stress distribution on the bonding surface is uniform, and there is no thermal impact and deformation on the parts.
- ◆ Structural adhesives are widely used in engineering, mainly for the reinforcement, anchoring, bonding, and repair of components — such as bonding steel, bonding carbon fiber, planting steel bars, crack reinforcement, sealing, hole repair, spike pasting, surface protection, concrete bonding, etc.
Frequently Asked Questions (FAQ)
Q
Does Saiqiang 999 neutral silicone structural adhesive require a primer before application?
No primer is required. Saiqiang 999 neutral silicone structural adhesive can form strong adhesion with most building materials directly without the need for any primer, simplifying the application process.
Q
What temperature range is suitable for applying and using this adhesive?
The adhesive can be applied when the surface temperature of the material does not exceed 50℃. After curing, it maintains good elasticity across a wide range of -50℃ to 150℃, making it suitable for various climate conditions.
Q
What colors are available for Saiqiang 999 neutral silicone structural adhesive?
The standard available colors are Black, White, and Clear. Custom colors can also be produced based on specific customer requirements.
Q
How should Saiqiang 999 structural adhesive be stored, and what is its shelf life?
It should be stored in its original packaging in a dry, ventilated environment at temperatures of 27℃ or lower. Under these conditions, the shelf life is 12 months from the date of manufacture.
Q
Is this adhesive suitable for long-term outdoor or wet environments?
While the adhesive offers excellent weather resistance against UV, rain, snow, and ozone, it is not recommended for use in areas that are permanently damp or submerged in water for extended periods.
Q
What materials is Saiqiang 999 structural adhesive compatible with?
It is compatible with a wide range of materials including reflective glass, laminated glass, silicone insulated glass, acrylic, polyethylene, metals, ceramics, plastics, rubber, and wood. However, it is not suitable for materials that exude oil, plasticizers, or other liquid organic substances.
