China 999 Neutral Silicone Structural Adhesive - Reliable Suppliers from Factory, 300ml for Building Materials
Characteristics
Can be squeezed out for use at any time.
Suitable for most building materials without producing adverse reactions or corrosive effects.
Generally does not require primer. After curing, it produces good adhesion to most building materials.
No primer required — forms strong adhesion with most building materials.
Basic Use
Dedicated to large-scale curtain wall engineering
Sunroom
Restrictions on Use
- ⚠️All materials that exude oil, plasticizers, and other liquid organic substances are not suitable.
- ⚠️When applying glue, the surface temperature of the material should not exceed 50℃ for construction.
- ⚠️After application, the adhesive has not yet solidified and cannot be completely sealed and isolated from the air.
- ⚠️It is not suitable to use in places that are damp all year round and submerged in water for a long time.
- ⚠️Ground pedestrian walkways should not be used in areas subjected to excessive friction and physical damage.
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
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
It 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.
No primer is required. Saiqiang 999 is formulated with excellent adhesion properties that allow it to form strong bonds directly with most building materials without any additional priming step.
The standard colors available are Black, White, and Clear. Custom colors can also be produced based on specific customer requirements.
The product 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.
No. This product is not recommended for use in permanently damp locations or areas where it would be submerged in water for long periods, as this may compromise its performance and durability.
After curing, Saiqiang 999 maintains good elasticity across a temperature range of -50℃ to 150℃, making it well-suited for both cold climate and high-temperature application environments.
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, among others — making it highly versatile for construction and engineering applications.
