Technical Specifications (HY-9055)
Both Component A and B are liquid with a dynamic viscosity of 3000±500 mPa.s, mixed at a 1:1 weight ratio. The operation time is 30-120 minutes, basic curing time 3-5 hours, full curing time 12-24 hours. After curing, it reaches Shore A hardness of 55±5, thermal conductivity ≥0.4 W(m.k), dielectric constant 3.0~3.3 (1.2MHz), volume resistivity ≥1.0×1016 Ω.cm and UL94-V1 flame retardant grade. All parameters are for HY-9055 model, with other models available for different application needs.
How to Use
1. Preparation: Fully stir Component A to mix settled fillers evenly; shake Component B thoroughly to ensure uniform material composition without stratification.
2. Mixing: Blend Component A and B strictly according to the 1:1 weight ratio, stir evenly to guarantee consistent curing and performance effects.
3. Deaeration (Optional): Place the mixed adhesive into a vacuum container, deaerate for 3 minutes under 0.08MPa to remove air bubbles, then ready for potting.
4. Potting & Curing: Pour the treated adhesive into electronic and electrical modules, place at room temperature for curing. Proceed to the next process after basic curing; note that temperature and humidity affect the curing speed.

FAQ
Q1: What packaging specifications are available for this potting compound?
A1: It is available in 5kg, 20kg, 25kg and 200kg packaging specifications, suitable for both small-batch testing and large-batch mass production.
Q2: What is the shelf life of the product and how to store it?
A2: The shelf life is 12 months when stored in a cool and dry place with sealed packaging; the colloid may stratify after storage, and stirring evenly before use will not affect performance.
Q3: Can the mixed adhesive be stored for a long time?
A3: No, the mixed A and B components should be used up at one time to avoid material waste caused by gradual curing at room temperature.
Q4: Is this product a dangerous good for transportation?
A4: It is a non-dangerous chemical and can be transported according to general chemical transportation standards, with no special transportation restrictions.
Q5: What should I do if the adhesive accidentally gets into the mouth or eyes?
A5: The product is non-toxic but avoid contact with mouth and eyes; rinse with clean water immediately if accidental contact occurs, and seek medical treatment if necessary.
