ZQ5688 structural adhesive

ZQ5688 Structural Adhesive is a two-component polymer silicone adhesive, A and B components are unpacked and mixed for use. It has good weathering resistance, UV resistance, ozone resistance, water resistance, non-corrosion, high and low temperature resistance (-50℃—+200℃), and high bonding strength. It does not contain solvents, has no pungent odor, and meets environmental protection requirements. With the help of special tools or packaging to extrude silica gel, it has fast curing after mixing, especially deep curing fast, high initial strength, fast curing can improve production efficiency, and achieve the expected bonding effect.

Product performance

ZQ5688 Structural Adhesive is a two-component polymer silicone adhesive, A and B components are unpacked and mixed for use. It has good weathering resistance, UV resistance, ozone resistance, water resistance, non-corrosion, high and low temperature resistance (-50℃—+200℃), and high bonding strength. It does not contain solvents, has no pungent odor, and meets environmental protection requirements. With the help of special tools or packaging to extrude silica gel, it has fast curing after mixing, especially deep curing fast, high initial strength, fast curing can improve production efficiency, and achieve the expected bonding effect.

Performance and usage requirements

The A component is a white paste-like gel, and the B component is a black paste-like curing agent. It is suitable for manual or machine coating. It is cured at room temperature, and the operation is simple and convenient. After the glue is applied, the glue surface is smooth, delicate and bright, and the glue surface has no sagging deformation, which greatly reduces the waste of glue. Surface curing time (non-sticking time) is generally about 10-30 minutes (high temperature in summer, curing faster, winter slower), deep curing time (hardness up to 20HsA) is about 2 hours. The low-molecular substance released during the A/B mixing and curing process is ethanol, which has a slight alcohol smell and is non-toxic and harmless to the human body. The glue is a green and environmentally friendly product.

Note: All mechanical and electrical properties are measured after curing for 7 days under the conditions of 25℃ and 55% relative humidity. The performance of each type of silica gel is subject to the actual test report.

Construction summary

1. Clean the surface: clean the surface of the adhered or coated object to remove rust, dust, oil and other contaminants.

2. Glue: Open the cap of the hose, put on the mixing tube, squeeze out the A and B component glue with tools at the same time, squeeze it to the cleaned surface through the mixing tube, make it evenly distributed, and close the adhesive surface to fix it .

3. Solidification: Place the glued or sealed parts in the air to allow them to solidify naturally; since the surface and the inside of this silicone are basically solidified at the same time, the initial solidification can be completed in about 2-5 hours, and it has a certain strength. , You can enter the next production process.

Safety notice

1. During the curing process of the sealant, low-molecular substances are released. The construction site should be ventilated to avoid discomfort due to excessive volatile concentration (no damage to the body after curing).

2. Avoid contacting the uncured sealant with eyes. If it comes into contact with eyes, please rinse immediately with plenty of water and seek medical attention in time.

3. Keep out of the reach of children when it is not solidified. If you accidentally swallow it, seek medical attention immediately.

Shelf life

Both components A and B should be stored in airtight containers at a storage temperature of ≤30°C, and the validity period is 6 months at 23-25°C in a closed state.
