Product Features & Advantages
1. High Optical Transparency: Light transmittance ≥90% at 400-800nm, haze ≤1%, clear and transparent, no impurities, no light scattering, meeting optical grade requirements, solving the problem of traditional foaming materials’ opacity and poor light transmittance.
2. Optical Stability: No yellowing, no discoloration after long-term use, high temperature or UV exposure, maintaining high transparency and optical performance, ensuring stable operation of optical equipment.
3. Transparency & Elasticity Balance: While maintaining high transparency, it retains good elasticity and toughness, can be processed into various optical auxiliary shapes, no brittle fracture, ensuring optical performance and structural stability.
4. Optical Compatibility: Compatible with HONG YE SILICONE’s high transparency Mold Silicone and optical grade potting compound, forming a complete optical grade solution, enabling one-stop procurement for optical buyers.
5. Easy Optical Operation: 1:1 simple mixing ratio, good flowability, no impurities, easy to fill into optical equipment gaps and molds, no professional optical operation skills required, improving production efficiency.
How to Use
1. Take Part A and Part B according to 1:1 weight ratio, use optical grade mixing tools, stir separately to eliminate sediment, ensure no impurities (avoid affecting transparency and optical performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure transparency and pore uniformity).
3. Pour the mixture into optical equipment mold or gap (paired with high transparency mold silicone), foam and cure at room temperature or by heating.
4. After full curing, the product is clear and transparent, no yellowing, no impurities, ready for use in optical grade scenarios.
Application Scenarios
Focus on optical grade scenarios: Optical equipment sealing (paired with high transparency mold silicone), optical component auxiliary parts (paired with optical grade potting compound), transparent electronic product filling (paired with Electronic Potting Compound), optical instrument protection (paired with Industrial mold silicone rubber), and transparent robot components (paired with robot silicone). It helps optical buyers improve product optical performance and market competitiveness.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, high light transmittance and low haze, meeting the optical grade procurement requirements of B2B buyers in optical, electronic and other industries, facilitating export to global optical markets.
Customization Options
