Core Product Technical Data (Selected Representative Models)
Product Advantages
1. Ultimate Reliability: The main chain adopts a Si–O–Si structure, with a bond energy of 444 kJ/mol, exhibiting excellent weather resistance. It withstands high temperature and high humidity, as well as thermal cycling and UV aging, while maintaining strong adhesion. Upon tearing, it displays cohesive failure, ensuring long-term stability.
2. Overcoming Industry Pain Points: To address issues with inadequate UV curing, products with shadowed areas no longer require side‑curing or reinforcing adhesives, thereby reducing process steps. For cover plates containing UV‑blocking agents, UV activation can be performed first, followed by automated curing.
3. Outstanding Optical Performance: Transmittance as high as 99%, haze ≤ 0.3%, and a refractive index consistently around 1.41, ensuring superior display performance.
4. Flexible constructability: It supports multiple processes, including dispensing, slot-die coating, and injection molding, with a high degree of automation, and is compatible with screens of various sizes, particularly large‑size and irregular‑shaped displays.
5. Environmental Protection and Safety: Non-toxic and odorless, compliant with environmental standards, and suitable for a wide range of indoor and outdoor electronic and optical products.
Product Performance Comparison
Compared with acrylic‑based LOCA systems, the SLOCA series offers distinct advantages:
● Weather resistance: SLOCA exhibits excellent weather resistance, whereas acrylic esters have poor weather resistance.
● Shrinkage rate: SLOCA has a shrinkage rate of ≤0.1%, whereas acrylates exhibit a shrinkage rate of 1–3%.
● Reproducibility: SLOCA has moderate adhesion and is easy to rework, whereas acrylates, with their high adhesion, are difficult to rework.
● Environmental friendliness: SLOCA is non-toxic and odorless, whereas acrylates may have an irritating odor.
Compared with LOCA adhesion, SLOCA is Reliability, light transmittance, thickness adjustment, dimensional adaptability, reparability, gap-filling capability It has greater advantages in various aspects.
Product Applications
● Typical application areas: In-vehicle displays, high-end smartphones, tablets, commercial display devices, and more.
● Substrate Compatibility: Suitable for a variety of transparent optical components, including glass, PMMA, touch screens, and display modules.
Betely SLOCA product series, renowned for its exceptional quality, has earned the long-term trust of leading customers in the industry, with substantial annual shipments, making it an excellent choice for full‑lamination bonding in display panels.
