Products features:
1. It’s special adhesives for sealing light pipe. It has low viscosity, good fluidity, de-bubbling and can be used for a long time. It’s easy to operate.
2. Curing in room temperature, curing speed is good, reaction is mild and heat release is uniform.
3. Contraction percentage is low after curing. Water-proof and yellowing-proof performance is good. Surface is flat and bright after curing, and hardness is adjustable.
4. Cured materials light splitting is uniform and electrical character is excellent, with good moisture-proof, heat resistance and atmospheric aging resistance.

Usage method:
Mix ratio: A:B=100:75(Weight ratio), mixing viscosity is 800-900cps at 25℃
Curing time: 1 hour at 50℃
Operational time: 45 minutes at 25℃
Curing condition: Well-mixed for 12 hours at 24℃, then demould. It will get to biggest hardness 48 hours later.
1. Products surface should be day and clean.
2. Group A will have a little precipitate. Stir group A for 5-10 minutes, then use it.
3. Exactly mix the group A and group B of 100:75, note that the ratio is weight ratio but not volume ratio. Stir the group A and group B evenly to ensure adhesive fully cure.
4. The adhesive can pot products after group A and group B are mixed.
Matters need attention:
1. The main adhesive and curing agent will react slowly after mixed, and viscosity will become higher slowly. Please use up the adhesives in operational time.
2. Keep and seal the rest adhesives well to avoid quality problem caused by moisture.
3. Don’t touch adhesives by skins and eyes. Clean with cleaner if skins touch adhesives; Clean with clear water if eyes touch adhesives, and ask for medical advice.
4. Test with small quantity and learn operating skills before use.
