product Performance

Performance before curing
appearance		Yellowish transparent liquid
viscosity (@25℃、rotary viscosimeter)		4500~6000 mPa·s
Condition of cure
The curing rate and depth of sd2600 are determined by the intensity of the light, the spectral distribution of the light source, the irradiation time and the transmittance of the adhesive material. The following data were measured under 110mw/cm² UV radiation from high-pressure mercury lamps:
positioning time (S)		2
Deep curing time (1mm, S)		5
tack free time (S)		5
Fully curing energy		300 mj/cm²
Performance after curing
The following data are measured after curing by 300 mj/cm² accumulated energy by a high pressure mercury lamp source
Hardness (D)		50
Bonding substrate (1 cm²)		bonding strength (kg/cm²)
Glass / metal		＞3
Weathering test
The following data are measured after curing by accumulated energy 300 mj/cm² of a high pressure mercury lamp source
Bonding substrate	test condition		Bonding strength retention rate (%)
Glass / metal	65℃90%RH(72h)		50

Storage:Store in a cool and shady place. Close well the bottle cap. Do not return the remain glue to the original bottle .The optimal storage temperature of 8-28 ℃, too high or too low temperature will affect the properties of the gel, the shelf life is 12 months.

Notes:this data is measured by the technicians of Sandao in the laboratory, which has certain reference value for the use of customers, but because of the different usage methods and conditions of each user, Users are advised to find out the best process and method according to their own situation.
