Low-temperature curing silicone coatings: construction efficiency and cost optimization

Hits: 141 img

Low-temperature curing silicone coatings significantly improve construction efficiency and reduce overall costs through technological innovation. Its core advantages and optimization paths are as follows:

1. Construction efficiency improvement technology
‌Low-temperature rapid curing system‌
Using platinum catalysts or peroxide catalytic systems, the curing temperature can be reduced to below ‌130°C‌ (traditionally requires above 180°C), and the time is shortened to ‌5-15 minutes‌‌.

Addition-type silicone coatings achieve low-temperature curing without small molecule byproducts through silane addition reactions, avoiding blistering defects‌.

‌Environmental adaptive process‌
Dynamically control formula: Add 3%-8% water and 0.5%-3% catalyst to accelerate curing in low-temperature environments (<15°C); reduce diluent to 1%-2% at high temperatures (>30°C) to prevent stratification‌.

When humidity is >80%, use oil-based primers instead of water-based formulas to reduce the risk of water absorption at the base layer‌. ‌Layered construction innovation‌
Alternate scraping method: each layer thickness ≤ 2mm, horizontal and vertical alternating construction to enhance the interlayer bite force, the interval time is shortened to 6-12 hours (traditional needs more than 8 hours).

2. Key measures for cost optimization
‌Material cost control‌
Adding 30% local quartz sand (40-80 mesh) to replace elastic material reduces the cost per ton by 800 yuan‌‌6.

Powder coating adopts recycling technology, and the utilization rate reaches more than 95%‌ (solvent-based coating is only 60%-70%)‌
‌Energy consumption and environmental protection cost reduction‌
Low-temperature curing (130℃) saves 30%-40% energy compared with traditional processes, such as the coating cost of a single device of the Ningde Times energy storage project is reduced by 25%.

VOCs are close to zero, eliminating waste gas treatment equipment (single production line saves more than 5 million yuan per year)‌

‌Durability Gain‌
Adding 0.1%-0.3% UV absorber (such as benzotriazole) can increase the weathering life to more than 10 years.
Adding elastic layer mixed with quartz sand in high-frequency areas, the compressive strength reaches more than 2.5MPa, reducing the maintenance frequency.

3. Industry Application Cases
‌Photovoltaic Modules‌: Baijia Era's patented technology realizes low-temperature self-curing after coating, improving the production efficiency of perovskite batteries.
‌Automotive Coating‌: Tesla Model Y wheel hub uses low-temperature curing powder coating, reducing the maintenance cost of the whole life cycle by 40%.
‌Building Coil‌: Silicone-modified coil coating is baked and cured at 180-220℃, with a weathering life of more than 10 years.
