◆Characteristics: This product is a single component UV-cured acrylate adhesive, light yellow transparent liquid. The product is specially designed for the bonding of the wiring, high viscosity, high touch degeneration, moderate curing speed, fall resistance, good weather resistance and other characteristics  

◆Environmental requirements: comply with RoHS Directive and relevant environmental requirements      

◆Reference standard: HG / T 3947-2007 single component room temperature silicone adhesive sealant

■Appliance

It is mainly designed for the bonding and fixation of various electronic components and glass and plastic substrate.

■Product performance before curing

surface ：Light, yellow, transparent and viscous liquid 

Viscosity (@25℃, rotary viscometer)：     18000mPa·s 

■Condition of cure

SD3056 Curing will occur under sufficient ultraviolet irradiation conditions, and its curing speed and depth will depend on the light intensity, the spectral distribution of the light source, the irradiation time and the light transmittance of the adhesive material. The following data were measured under the ultraviolet light radiation conditions of 110mw / cm2 produced by the high-pressure mercury lamp:

positioning time (S)              4

Deep curing time(1mm, S)          15 

Deep curing time             1000 mj/cm2

■Product performance after curing 

The following data are measured after the curing of 1000 mj / cm2 HHP source:

Hardness (Shao D)                  60

Hardness (Shao D)（/℃）         8.2×10^-5 

Hardness (Shao D)          Hardness (Shao D)

PC/PVC                           ≥7.5

Stainless steel / GLASS           ≥7.5

■Weather resistance test 

The following data are measured after the cumulative energy of 1000 mj / cm2 of the mercury lamp source：

■Use method and matters needing attention

※One of the two bonded objects is transparent and clean, dry and free of grease

※Apply UV shadow glue on one of the surfaces, close the two planes, with the appropriate wavelength (usually 365nm-400nm) and energy ultraviolet lamp or lighting with high pressure mercury lamp, from the center to the periphery, and confirm that the light can indeed penetrate to the adhesive part;

※It is suggested that when the light is about 6s and the preliminary positioning, remove the remaining glue on the workpiece and then re-light to complete curing;

※It is suggested that when the light is about 6s and the preliminary positioning, remove the remaining glue on the workpiece and then re-light to complete curing;

※The temperature also has a little influence on the activity of the glue, and the curing time should be appropriately extended when the temperature is low;

※No force extrusion and repeated friction of adhesive materials in the operation, and it is recommended to use fixed tools;

※When plastic bonding, the content of ultraviolet absorber in plastic should be considered, and the high content will seriously affect the transmittance of ultraviolet light, which also has an obvious effect on the curing efficiency of glue, and even lead to the failure of glue curing;

※Low-viscosity products are recommended for large-area bonding. If the conditions are available, it is best to purchase vacuum equipment and fit in the vacuum environment, in order to remove bubbles and improve the yield;
