LED bulb lamp potting with glue requirements is introduced

by:Sehon     2020-11-03

surveying of land under the led lighting manufacturer to tell you about the led ball bubble lamp potting with glue of requirements:

1, led lamp holder structure adhesive:

metal or PC and PC/PMMA and PC/PMMA adhesive sealing, use room temperature curing one-component glycol type silicone sealant, for aluminum, copper, stainless steel and other metal has good adhesion; Performance tuning, the more heat resistant performance is good, generally use temperature range - 60℃~200℃。 Released in the process of solidification is alcohols, polycarbonate ( PC) , optical acrylic ( PMMA) , copper and other materials, no corrosion, completely in line with the eu ROHS directive requirements.

2, LED lens bonding fixed:

high performance adhesive sealing silicone rubber is a single component, paste, translucent, take off the alcohol at room temperature vulcanized silicone rubber. Neutral curing, bonding material no corrosive, formed after curing rubber elastomer, adhesive range, excellent mechanical can, good impact resistance. Heat resistance and wave resistance and cold resistance, under the condition of high temperature and high humidity remains good mechanical performance, not white, low yellowing. Excellent insulation, moisture, shock, corona resistance, electric leakage resistance and resistance to chemical media performance.

3, LED bulb light Thermal conductive adhesive glue requirements:

coefficient of thermal conductivity: 0. 8 to 1. 2

viscosity: cream

high coefficient of thermal conductivity, good insulation, easy to operate

low earthquake, avoid mechanical damage, on the base material without corrosion;

low maintenance, easy disassembly.

'can be used for severe temperature cycle application occasions;

good then performance, dispense with the traditional mechanical fixation;

4, LED bulb light Sealing with adhesive requirements:

1. High thermal conductivity, 0. 5 to 0. 8) ;

2。 Good row of bubble ( Viscosity 3500 CPS)

3。 Rapid solidification ( Mass production, 80 & deg; 30min)

4。 Flame retardant
