The test methods evaluated include penetration resistance, initial surface adsorption, surface temperature, reflectance, relative humidity, and dielectric constant. A factorial experiment was set up for field testing, and the test methods were

red resin composite material was removed with a plastic spatula (3). The top surfaces of the specimens were iden-tified with an indelible mark. Specimens were stored in light proof containers before the tests were conducted, in complete darkness at 37 C for 24 hours to prevent ambient light from causing additional post light-curing

Z100 composite (Micro-hybrid) restorative material is visible-light activated, radiopaque, restorative composite restorations. . The composite resin was cured with a light curing unit for 40 seconds on both sides of the mold through the glass plates to standardize curing distance (1.35mm). .

The curing of samples was carried at room temperature for 24 hrs. Slowly poured in glass tubes so as to get cylindrical specimens (diameter 12 mm, length 120 mm). The hard- ened composite samples are extracted from the glass tube. A releasing agent (Silicon spray) is used to facilitate easy removal of composites from the glass tube after curing.

resin can also be used as a curing agent for epoxy and has a synergistic effect with epoxy. Rimdusit et al. mixed BA-a benzoxazine monomer, epoxy resins, and amine curing agent to produce a new SMP system [46-48]. They had higher bending strength and bending modulus, as shown in Figure 4(f). Subsequently, they used aniline-based ben-

Group two: after using 37% phosphoric acid and rinsing with copious water as described in group one, Excite bonding agent (Ivoclar, Vivadent, Schaan, Leichtenstein) was applied by a micro brush on the surface of the composites resin that were treated. After light curing of the Excite

prestressed concrete, use expensive ac-celerated curing techniques to achieve high early concrete compressive strengths. In many precasting opera-tions the early target strength of freshly cast products can be as high as 4500 psi (31.0 MPa) after only 14 hours. To attain such strengths, the concrete mix designs usually have a high cement content.
