In the field of display screen assembly, the performance of adhesives directly affects display quality, durability, and production efficiency.
Betely's SLOCA series of silicone liquid optical adhesives for full lamination bonding stand out with exceptional reliability, broad applicability, and innovative technology, making them the ideal choice for display bonding.
Product Highlights
The SLOCA series is a high-performance silicone liquid optical adhesive specifically designed for full lamination bonding. It includes UV-thermal cure, thermal cure, and other product types, complemented by gap fillers and dam adhesives, offering a comprehensive bonding solution.
Product Technical Data
Product Advantages
Superior Reliability
Built on a Si–O–Si backbone with a bond energy of 444 KJ/mol, SLOCA provides outstanding weather resistance and durability under high temperature, high humidity, thermal cycling, and UV exposure. It delivers strong adhesion and demonstrates cohesive failure upon peeling, ensuring long-term stability
Industry Pain Point Breakthrough
Addresses issues of UV curing failure: products with shadowed areas no longer require side curing or reinforcement adhesives, reducing process complexity. For cover glass containing UV blockers, UV activation followed by auto-curing is supported.
Excellent Optical Performance
With light transmittance up to 99%, haze ≤0.3%, and a consistent refractive index of ~1.41, SLOCA ensures outstanding display clarity.
Flexible Processing
Compatible with multiple dispensing methods — dot dispensing, slit coating, and injection — supporting high automation. It adapts well to different screen sizes, especially large-format and irregular-shaped displays.
Performance Comparison
Compared with acrylate-based LOCA, SLOCA offers significant advantages:
Weather Resistance
SLOCA: excellent; Acrylates: poor.
Shrinkage Rate
SLOCA: ≤0.1%; Acrylates: 1–3%.
Reworkability
SLOCA: moderate adhesion, easy to rework; Acrylates: high adhesion, difficult to rework.
Environmental Safety
SLOCA: non-toxic, odorless; Acrylates: may produce irritating odor.
Overall, compared with conventional LOCA, SLOCA demonstrates superior reliability, transmittance, thickness control, size adaptability, repairability, and gap-filling ability.
Product Applications
Typical Use Cases
Automotive displays, premium smartphones, tablets, commercial display equipment, and more.
Substrate Compatibility
Suitable for a wide range of transparent optical components, including glass, PMMA, touch panels, and display modules.
With proven quality, Betely's SLOCA series has earned long-term trust from leading industry clients. With substantial annual shipments, it stands as a premium choice for full lamination display bonding.
