999 Neutral Silicone Structural Adhesive - High-Quality China Suppliers & Factory - 300ml Room Temperature Cure
Characteristics
- Easy to use: Can be squeezed out for use at any time.
- Neutral curing: Suitable for most building materials without producing adverse reactions or corrosive effects.
- Good adhesion: Generally does not require primer. After curing, it can produce good adhesion to most building materials.
- Excellent adhesion: No primer required — forms strong adhesion with most building materials.
Basic Use
Dedicated to large-scale curtain wall engineering
Sunroom
Restrictions on Use
⚠️ Please note the following usage restrictions:
- 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 that are 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
📦 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℃ to 50℃, making it easy to extrude and use. It maintains good elasticity at -50℃ to 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, and ceramic glass.
- Can 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.
- Stress distribution on the bonding surface is uniform, with no thermal impact and deformation on the parts.
- Structural adhesives are widely used in engineering for reinforcement, anchoring, bonding, and repair of components — including bonding steel, bonding carbon fiber, planting steel bars, crack reinforcement, sealing, hole repair, spike pasting, surface protection, and concrete bonding.
