AI Technical Summary

Problems solved by technology

Therefore, if the final product is damaged or malfunctions, it cannot be repaired
[0006] Methacrylic slurries containing MMA require complex molding know-how; in fact, special molds and delicate molding processes must be used
[0007] Furthermore, due to the presence of cross-linking agents, the mixture of quartz mineral filler and MMA-containing methacrylic acid slurry creates a network of highly chemically bonded and highly cross-linked quartz mineral filler, thus rendering the final product impossible to thermoform or process

[0114] Example 2 (polyester+0.3%TiO 2 +ATH) (this invention)

[0115] Mix the following components in a 1000cc high density polyethylene container using a screw agitator (900-1800rpm):

[0116] - 420.00 grams of polyester POLYLITE 32166-16REICHHOLD;

[0117] - 6 g of silane DYNASYLAN MEMO 3-trimethoxysilyl)propyl methacrylate;

[0118] Then add the following components:

[0119] -3 grams of TiO produced by DEGUSSA 2 P-25;

[0120] The minimum mixing time is 2.5 hours before adding the following components:

[0121] - 559.2 grams of ATH (aluminum oxide trihydrate) mineral filler, less than 50 microns in size

[0122] - 4.00, 3.00, 12.00 grams of cross-linking agent, respectively EGDM-TEGDM-TMPTM;

[0123] - 1.5 g of zinc stearate.

[0124] A mixture of approximately 0.06 and 0.07 grams of variable amounts of methacrylic acid and isopropylamine was used as the silylation catalyst.

[0125] Then, the mineral filler and zinc stearate are added and the dispersion is sti...

Embodiment 3

[0127] Example 3 (polyester and MMA solution + 0.3% TiO 2 +ATH) (this invention)
