LED Strip Light Silicone analysis of the advantages

 
Currently on the market there are epoxy potting , Polyurethane and silicone sealant products of these three systems . These three products have different characteristics . Epoxy potting generally AB component packaging products with good light transmission rate is usually 85-92 % in terms of transmittance between ; piled high with good effect after curing lights bright appearance sleek curvature ; can -5 ℃ to 55 ℃ for use ; itself, but because of the characteristics of the epoxy resin Tg point is lower toughness at high temperatures and is prone to deterioration often exceed 60 ℃ when the soft light appeared to soften plastic prone to breakage resulting colloid ; while temperatures below -5 degrees Celsius colloidal hard brittle light bar will appear slightly shaking stripping and brittle fracture colloidal phenomena ; lamp beads 400-700 hours after long-term light lamp beads above the epoxy gel becomes khaki light levels fall and cause changes in color temperature .
 
Polyurethane PU glue is generally known as AB packaging products in 85-92 % transmittance between the solidified strip has good flexibility after curing gel at -25 ℃ to 95 ℃ between long-term use ; but unable to do so is very low hardness polyurethane gel products only applies to Epoxy -type or semi- sleeve type soft light strip light strip as the temperature decreases the flexibility of a larger change ; potting surfaces and when FPC If you require a higher humidity excessive humidity mist and product surface prone to insufficient adhesion phenomena ; long-term outdoor use colloidal usually occurs 2-3 years yellowing phenomenon .
 
Silicone sealant is generally one-component or AB -component packaging products is generally 84-92 % transmittance between the hardness of the cured gel can be made into jelly type adjustable both gel can also be made shoreA30 degrees so hard rubber silicone encapsulants can be used either epoxy -type light bar can also be used for semi- tube -type light bar can also be used for full -tube strip cured gel in the -45 ℃ to 200 ℃ between the use of products as the temperature changes and mechanical and physical properties and optical properties will not be significantly changed. Very suitable for Russia , Scandinavia, North America and other areas using cold ; silicone sealant strip ozone , ultraviolet light, acid and alkali better performance can be maintained long-term outdoor use non-yellowing ; But there are also silicone sealant with FPC piled high adhesion of the epoxy is slightly lower than other defects .
 
From the development of the market in terms of silicone sealant to replace other LED Tube light  products the trend is more and more obvious if it is necessary to use in harsh environments lights must be used silicone sealant .
