The addition of reactive diluents, including 10% TMPTA and 20% HDDA
, into EMA-P resin lowered our formulation viscosity to 7PaS '.

Concentration of peroxide and HDDA
relative to PP powder (mmol/kg) and the type of peroxide used lor modifying PP.
The TSB or TST was added into the mixture of TMPTA and HDDA
, and treated with ultrasonication for 30 min, then added into EA oligomeric resin and ultrasonicated for another 30 min, followed by addition of Irgacure 651.
Available dispersed in DPGDA, HDDA
, TPGDA, plus custom bases.
According to supplier literature, these monomers exhibit enhanced hardness, scratch resistance, impact strength, and abrasion resistance as compared with industry standard monomers, such as HDDA
Two bifunctional monomers, HDDA
and TPGDA, manufactured by Aldrich Co.
It could eventually be used as a substitute for conventional HDDA
