Stor­age

RBcure-2100 is sen­si­tive to vis­i­ble light and any expo­sure to sun­light should be avoid­ed. Opened drums should be sealed after use to pro­tect the prod­uct from light. RBcure-2100 will freeze when stored below –20 °C ( – 4 °F). Stored for extend­ed peri­ods of time below
6 °C (43 °F), some crys­tal­liza­tion may occur. In both cas­es, the prod­uct is restored to its orig­i­nal form by stir­ring at room tem­per­a­ture for a short time.

Known Appli­ca­tion

RBcure-2100 may be used in UV-cur­able for­mu­la­tions for clear and for pig­ment­ed coat­ings on wood, met­al, plas­tic, paper and opti­cal fibers as well as for print­ing inks, com­pos­ites and adhe­sives. For patent rea­sons, how­ev­er, the use of this prod­uct is not allowed in den­tal appli­ca­tions. RBcure-2100 is suit­able for white pig­ment­ed for­mu­la­tions, wood fillers and UV-sta­bi­l­ized, UV cur­able var­nish­es.
It is espe­cial­ly suit­able for white pig­ment­ed for­mu­la­tions with min­i­mal yel­low­ing after cur­ing and for coat­ings with low pig­ment vol­ume con­cen­tra­tion.
Suit­able UV-cur­able for­mu­la­tions may be based on acry­late resins, acry­late monomer sys­tems and unsat­u­rat­ed poly­esters. As a liq­uid pho­­to-ini­­ti­a­­tor, RBcure-2100is espe­cial­ly easy to incor­po­rate into for­mu­la­tions.
RBcure-2100 can be used as a sole pho­­to-ini­­ti­a­­tor but in most cas­es com­bi­na­tions with oth­er pho­­to-ini­­ti­a­­tors, e.g., α-hydroxy ketones or phenyl gly­oxy­lates, will give improved bal­ance between through- and sur­­face-cur­ing performance.
