What Structural Adhesive is Recommended for Installing 304 Stainless Steel Sandwich Insulation Panel?
When installing 304 stainless steel sandwich insulation panel, choosing the right panel is only half the battle; choosing the right structural adhesive is equally important. The structural adhesive bears not only the simple task of 'sticking', but also must withstand sun and rain, thermal expansion and contraction, rainstorm impact, and must not have problems over ten or twenty years. So, what structural adhesive should be used for installing 304 stainless steel sandwich insulation panel? The industry-recognized answer is silicone structural adhesive.
I. Why Choose Silicone Structural Adhesive?
1. Excellent weather resistance: Silicone structural adhesive can maintain stable performance in extreme climates from -40°C to 150°C, not aging or cracking.
2. Strong adhesion: It has excellent bonding strength to stainless steel, aluminum, glass and other materials, with tensile strength up to 2.0MPa.
3. Good elasticity: Can absorb thermal expansion and contraction stress caused by temperature changes, preventing panel deformation.
4. Waterproof and moisture-proof: After curing, it forms a flexible waterproof seal, effectively preventing moisture infiltration.
II. Recommended Product Specifications
It is recommended to choose neutral silicone structural adhesive that meets the following standards:
- Executive standard: GB 16776-2005
- Modulus: Medium modulus (suitable for metal panel installation)
- Curing method: Deoxime curing (no corrosion to metal)
- Service life: More than 25 years
III. Construction Precautions
1. Base surface treatment: Ensure the bonding surface is clean, dry, and free of oil and dust.
2.
3. Curing time: Initial curing takes 24 hours, complete curing takes 7 days. Avoid loading during the curing period.
4. Construction environment: The construction temperature should be 5-40°C, and the relative humidity should not exceed 80%.
IV. Brand Recommendations
It is recommended to choose well-known brands such as Baiyun, Zhijiang, and An Tai, which have stable product quality and complete after-sales service. Avoid using unbranded low-price products to prevent quality hazards.
