DYMAX 3094-T/3069-T

UV wave  range  ,  including  UVA(320- 700nm) ,  UVB(280- 320nm) , UVC(200-280nm) .

UVA  320- -400nm Deep cure  bad tack free Deep cure  bad tack free

UVB 280- -320nm  Superficial cure and good tack free Superficial cure and good tack fre

UVC 200- -280nm Surface cure and best tack free Surface cure and best tack free

The  spectral   of  365nm  LED  lamp  are  as  below  ,  there   is  no UVB and  UVC and will get a bad tack free . The surface can not be cured .

When cured with Dymax 5000- EC as below graph upon a intensity of

The Tack free of 3094-T

When  cured  with   Dymax 5000-EC ,  as below   graph  ,  upon  a  intensity of  200mW/cm2 (D bulb), the adhesive can be cured for 2mm within 5 seconds .The adhesive can have a depth cure while  there is some kind of wet in the surface , it will not effect the adhesion of Dymax adhesive 3094-T.

Conclusion

1. Dymax 3094-T is a UVA/UVV curable adhesive , the photo initiator will react with UV light when exposed to the light wavelength from 320nm-420nm , the 365nm LED lamp cannot full y  cure D y max 3094-T ; pyy ;

2. When using 3094-T cured by Dymax 5000-EC (D bulb) , the adhesive can have a depth cure , though there is still some kind of wet on the surface , it’s OK ; d ring the c ring process the tack s rface ca sed b the o gen This during   the  c uring   process  ,  the  tacky  s urface  caused  by  the   oxygen .  This tacky surface doesn’t effect any cured adhesive properties ;

3. We suggest that we use Dymax 5000- EC or Dymax BW200 to cure our 3. We suggest  that   we use  Dymax 5000 EC or   Dymax BW200 to  cure our adhesive 3094-T , as when we design this adhesive , we use these two equipment to evaluate the cure character;

4 It ill b b tt if h t f D 5000 EC ith h t H 4 . It  will   be  be tt er if  you can  have a  t ry o f   D ymax  5000-EC with s hor t  wave H  bulb , which can get a better tack free .
