PERFORMANCE

 Low viscosity, easy flow, convenient molding operating. Good adhesion

 No color, no poison, no solvent.

The above is the main materials parts, there are necessary accessory materials: (1) Color paste should be added about 1% weight of epoxy (Try best Color by self)

(2) Dodging agent suit for big or small signs.

USAGE

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

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

   to avoid epoxy leak out.

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. Pouring the second layer by A + B + Dodging agent + Color paste ( 5A + 2B + (2-3)% Dodging agent +

(0.5-1)% Color paste). The ratios of Dodging agent and Color paste are according to the weight of A component. This layer should be full in LED models.

Cured in room temperature, or cured by heating.

 Repair to perfect

 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.

NOTICE

 A component should be preheat to 50-60°C for easy operation and the best effecting.

 Implements of stirring, mixing and measuring should be clean.

 When stirring, need toward one direction and slowly to avoid bubbles. Rest 5-10min after mixed before pouring. Pouring by one side to avoid bubbles too.

STORAGE

 A and B components should be put in ventilate, dry, shady place.

 B component is easy to moisture absorption, need to seal in time.

 Shelf life one year.
