In recent years, domestic environmental protection supervision has been continuously strengthened. The VOC emission reduction, clean production, and safety production standards in the paper and paper product processing industry have been comprehensively upgraded. The traditional solvent-based silicone oil coating process has many drawbacks such as large exhaust gas emissions, pungent odor, flammability and explosiveness, and high operation and maintenance costs. It gradually fails to meet the production requirements of modern green factories. Against this backdrop, water-based emulsion silicone oil, with its advantages of low VOC, environmental protection, no odor, safety and stability, and convenient construction, has become the core preferred raw material for the green transformation of specialty paper enterprises. It is widely used in release paper, waterproof packaging paper, craft card paper, and cultural paper products for upgrading and renovation.
Water-based silicone oil uses pure water as the only dispersing medium and does not contain organic solvents. There is almost no volatile exhaust gas emission during the coating, curing, and storage process. No complex exhaust gas treatment equipment is required, which significantly reduces the enterprise's environmental protection investment and operation and maintenance costs, and is in line with the national low-carbon production and green manufacturing policy orientation. Compared with solvent-based silicone oil, the water-based emulsion system has stronger storage stability. It is not prone to stratification, demulsification, or deterioration at room temperature, and is safe during transportation and construction, completely eliminating the risks of flammability and explosiveness, significantly improving the safety level of the production line.
In terms of application performance, water-based silicone oil has strong versatility and can be adapted to mainstream high-speed coating machines, immersion equipment, and sizing equipment on the market. Enterprises can directly start production without modifying the production line, and can meet various modification requirements such as release protection, paper waterproofing, soft base material, and surface anti-slip. After curing, it forms a uniform and fine silicone-based functional film, completely retaining the core advantages of silicone oil such as water repellency, anti-adhesion, softness, and wear resistance. At the same time, it avoids the common appearance defects of solvent-based silicone oil such as fogging, shrinkage, rainbow patterns, and poor adhesion. It significantly improves the appearance texture and quality consistency of paper products.
The product application scenarios are wide. Label release paper, food waterproof packaging paper, art card paper, furniture moisture-proof paper, and cultural specialty paper can all be used stably. After modification, the paper retains good air permeability, printing performance, and degradability, and does not affect subsequent processes such as hot stamping, lamination, die-cutting, and printing. It also takes into account environmental protection and practicality.
Industry statistics show that in the past two years, the purchase growth rate of water-based environmental-friendly additives in the paper industry has exceeded 26% annually. Water-based silicone oil has completely replaced traditional solvent-based products and become the mainstream. Domestic IOTA water-based silicone oil can customize formulas according to paper machine speed, coating amount, and paper material, adapting to differentiated production needs, and helping paper enterprises achieve triple breakthroughs in green production, quality improvement, and cost optimization.
