Second, use:
1. Use ratio: E-400A glue: E-400B glue: phosphor = 1: 1: (0.06 ~ 0.16)
2. Baking conditions: 150 ° C for 90 minutes
3. Dispensing: recommended dispensing to the convex cup is appropriate
Third, save the conditions and duration
1. Storage conditions: low temperature dry, dark, sealed
2. Shelf life: 3 months
3. Product packaging is divided into: 500 grams / bottle, 1000 grams / bottle, special packaging to be negotiated.
Fourth, note:
1. This glue is designed for the use of phosphor modulation, in use can not participate in other substances, otherwise it will lead to damage to its performance, can not achieve the desired effect.
2. White glue and phosphor stirring evenly vacuum, please vacuum machine temperature control in the 60 - 70 degrees is appropriate.
3. The deployment of a good phosphor in a short time spent (recommended within 2 hours), not long exposure to the air. |
