The first component of the two-part forming mixture may include an amino silicone component, a filler composition, and a silane component. The second component may include an aldehyde component.
According to yet another aspect, a method of forming a silicone-based sealant may include providing a two-part forming mixture that may include a first component and a second component, and combining the first component and the second component where the second component chemically reacts with the first component to form the silicone-based sealant. The first component of the two-part forming mixture may include an amino silicone component, a filler composition, and a silane component. The second component may include an aldehyde component.

A representative two-part forming mixture Sample S1 is utilized to form a sealant Sample S2. The composition of Sample S1 is noted in Table 1 below.
Sample S1 is prepared as follows. An initial mixture of aminopropyl-terminated polydimethylsiloxanes and octyltrimethoxysilane is made using SpeedMixer® (from FlackTek) at 3000 RPM for 1 min. Fumed silica and calcium carbonate are then added, and the mixture is mixed for another minute at the same speed to form the first component of Sample S1. If a double-barrel cartridge (10:1 ratio) is used, the first component is transferred to the large barrel and the second component, formalin solution (8 wt. %), is added to the small barrel. The cartridge is loaded on the extruding gun and the mixture of Sample S1 is extruded on a PET release liner that is submerged underwater.
If a single barrel is used, after the first component is added, air is removed from the barrel, and then the barrel is capped. Formalin solution is then added through the extrusion hole. A static mixing tip is then attached, and the mixture is extruded on a PET release liner that is submerged underwater.
Sample S1 is submerged, and the skin time is approximately 15 sec.
Sealant Sample S2 is released from the liner for property tests included in Table 2 below. Hardness is determined using the portable shore A and shore 00 durometer according to ASTM D2240. Elongation-at-break is tested using Instron® tensile tester according to ASTM D638. Tear strength is tested using Instron® tensile tester according to ASTM D624. Lap shear strength is tested using Instron® tensile tester according to ASTM D906 and ASTM D1002.
Another sealant sample S2 is formed to seal a leakage of a water container. The first component of Sample S1 is prepared as described above. A double-barrel cartridge is used. The extruding gun is extended under water and the mixture is extruded to cover a hole of the container. The mixture gelled in 15 seconds and leakage of water is stopped.
Gel time is tested on 2-part forming mixture samples including different contents of the first component. The first component is prepared in the same manner and has the same composition as described with respect to Sample S1. The first component is mixed with formalin solution at different weight ratios so that the final mixtures include approximately 65 wt. %, 74 wt. %, 85 wt. %, 87 wt. %, 90 wt. %, 91 wt. %, and 92 wt. % of the first component relative to the total weight of the respective mixtures. Gel formation is examined as described in embodiments herein with respect to skin time. As illustrated in
Two-part forming mixture samples are prepared, and skin time is tested on the mixtures. The mixtures are prepared in the same manner as described with respect to Sample S1. The compositions of the samples are noted in Tables 3-7 below.
The contents of the amino silicone component of the samples are noted in Table 8. Skin times for the samples are determined as described in embodiments herein. The viscosities are tested on the first components of the samples by using a rheometer (TA Instrument HR-30) with a 25-mm parallel plate. The frequency sweep is performed by ranging the frequency from 0.01 s−1 to 100 s−1. Skin time of the mixtures and viscosities for the first components are included in Table 8.
It can be observed that skin time decreases with increases of the contents of the amino silicone component. Gelation is not detected in the mixture having 30 wt. % of the amino silicone component for the total weight of the first component. Skin time is approximately 60 seconds for the mixture having 50 wt. % of the amino silicone component for the total weight of the first component. Samples S6 to S8 demonstrated similar gel time, approximately 15 seconds, which is significantly faster compared to Sample S5.
As illustrated in
Skin time is tested on mixtures including different amino silicones as noted in Table 9 below. Formulas of telechelic and pendant amino silicones are illustrated in
Additional sealant Samples S20-S22 are made using 2-part forming mixtures S10-S12, respectively. Compositions of the mixtures are included in Tables 5-7 below and prepared in the same manner as described with respect to Sample S1. The mixtures are expected to cure in approximately 2 min when submerged. Properties of the sealant Samples S20-S22 are to be tested and expected to be satisfactory. Properties to be tested include those noted in Table 2.
A sealant is formed under water using the 2-part formulation in Table 13.
The first component and the mixture of the first and second components is prepared in the similar manner as described with respect to Sample S1. The mixture is extruded on a PET release liner that is submerged. The mixture demonstrates the gel time of about 20 seconds and cures in about 2 min.
