USAGE                                                                                                                         

Usage of epoxy resin for LED signs (Operational approach for pouring type LED shine letters)

1,Put LED models in right way, the connector between line and mould should be sealing by silicone sealant

   to avoid epoxy leak out.

2,Pouring the first layer by the mixed epoxy resin ( just 5A and 2B).Stop until 5mm to full for next step. 

This layer thickness is about 2cm.
3,Pouring the second layer by A + B + Light diffusion agent + Color paste ( 5A + 2B + (2-3)% Light   

diffusion agent + (0.5~1)% Color paste). The ratios of Light diffusion agent and Color paste are according 

to the weight of A component. This layer should be full in LED models.

4,Cured in room temperature, or cured by heating.

5,Repair to perfect

6,Suggestion: a) Reflectorized paint can be coated in inside of LED model for saving lights.  

b) Control the lays thickness, above first and second layers for 2.5-3cm LED signs.
